The Full Prelude

Outskirts of Chicago, September 20 1986, 1 AM

It’s a sausagefest down at ‘The Bunker’ tonight - seven guys and - being that Jerry left with his girlfriend at a more reasonable hour of the night - no women to speak of. Then again, it’s not exactly a surprise.

Let’s take a step back. “The Bunker” is just a monstrously uncool name assigned to a large-ish house just outside Chicago, and it serves as the headquarters of a local metal band who call themselves Ruinous Revolt. The drummer of this band - David - got the place as inheritance from his late father, and offered it up for the band because out here, there’s nobody to place a noise complaint - and if anybody did, there’d be nobody to answer it. This made the inconspicuous domicile the perfect place to turn alcohol and other substances into idealistic philosophical ramblings they could hopefully turn into music.

Even without any company from the fairer sex, it’s a happy Saturday night for the four members of Revolt and their free-rider friends: they’d been on a roll lately with local gigs, netting them a whole bunch of bank on top of the four’s day jobs. The cause of their get-together was that in just 16 hours, Ruinous Revolt would open for a much more prominent band at a legit show, with many thousands in attendance - fertile ground to grab the attention of record execs and the like. Being men barely into their twenties, the only thing on their mind was: what to spend all the dough on.

David, the aforementioned drummer, was at peace about it, planning to save or invest his share. John, the guitarist… You already know what he was planning to get, let’s be honest. And that dimwitted bassist, Luke, was probably thinking of going on a spiritual journey or something of the sort. Crazy what certain plants do to people’s psyches.

But Robert, the thunderous vocalist whose crowd-pleasing antics arguably (at least in his head) paved the way for Ruinous Revolt’s success? He wanted both an outlet for his need to show off and a cause for the adrenaline rushes that always gave him lyrical inspiration. Robert wanted a new, capable sports car, something capable of giving him a physical rush.

Of course, Luke immediately started rambling about the futility of worldly possessions. David pointed out that if Rob got a car that handled well, he could have fun on country roads without even breaking the speed limit… To which John, a Kentucky transplant whose uncle was an actual moonshine runner, immediately snapped that nothing could be further from the truth, and that jaw-dropping acceleration - as well as the threat of getting arrested - were essential to getting good thrills out of a fun car.

The above, of course, meant that Rob had gotten no help at all, rather his options remained wide open: he didn’t know whether he wanted a car that handled or a car that just up and went, and whether or not he could get both without breaking the bank. And speaking of the bank, Rob - boisterous as he was - had not been wasteful with his money prior to his band’s big break, and could be sure that he could spend up to around fourteen grand on a new ride… though the upper end of that was pushing it somewhat.

Some would say - an in fact, David did say - that Robert could just wait until things worked out for sure, then buy himself a Pantera or something. Yeah, right, sounds glam. But after four years of rattling along in a Chevette gotten nigh-on for free, it was high time for a change.

TL;DR: member of up-and-coming band needs a new car to show off and to get in the zone. As the band isn’t far along on the up-and-coming curve, the budget is limited.


Model and Trim

  • Years: Model Year - unrestricted; Trim Year - 1987.
  • Body: Sedan, Coupe or Hatchback all allowed. 2 doors or more.
  • No Legacy Car Bodies - if you mouse over a body and it says “Legacy Car Bodies” in the Mod Name tab, it’s banned.
  • Suspension: For balance reasons, I am prohibiting the use of Rear Multilink.
  • Wheels: Radials required.
  • Interior: 2 seats or more.
  • Safety: 80s or newer, any grade.
  • Price (as per Detailed Stats): No more than AM$14,000
  • Exterior Features/Fixtures: As seen below, design and realism are both high priorities. Breaks from convention or minor hickups like missing a third brake light won’t earn a bin by themselves, of course, but they may decrease your entry’s competitiveness. If you’re literally missing taillights? Yeah, that’s a bin.
    Properly lighting categories (e.g. taillights, brake lights, reverse lights that light up separately) are not required and won’t be considered in judging.
    Headlights of all types are allowed: Sealed-beam, composite, hidden headlights in either an open or closed position are fair game.


  • Years: Family Year - unrestricted; Variant Year - 1987.
  • Architecture: No V16s.
  • Aspiration: Boost limit may not exceed 10.88psi/0.75 bar, inclusive. Twin-scroll turbos not allowed.
  • Fuel System: No Race intake. Unleaded fuel required.
  • Exhaust: Catalytic converter (any three-way) required. At least one muffler required. No Racing Tubular or Turbo Racing headers.
  • Loudness: 50 or less.


All entries start with 2 techpool in each area, except for turbo - where you start with zero. This makes for 30 points in total. You may add 45 points on top of that, for a total of 75 techpool. Each techpool area is limited to a maximum total of 7 points. I advise every entrant to double-check their techpool before submitting - as this time, there will be no re-submissions.

If your installation of automation has exported the wrong techpool values in the past, you may send a screenshot of your techpool screen alongside your entry, in the same DM. In all cases where such a screenshot is sent, I will double-check your submission’s values with those on the screenshot, and correct if necessary.

If you do not use this feature and the techpool ends up wrong - or if the techpool sum on your screenshot is invalid as well - you will be binned.

The default techpool allocation

Advanced Trim Settings

  • Visibility: Unrestricted
  • Wheels: Wheel Width, Diameter, Camber banned due to the fact you can change those in the car’s actual engineering. The rest of the settings, such as Wheel Offset are allowed in reason and moderation; if the car looks straight out of Wacky Races, God rest your soul.
    Tyre diameter, tread width banned; sidewall and tread curve allowed in moderation - whether to make them more period-correct or to make one of Aruna’s dang whitewall/writing tires look good.
  • Body: Front & Rear Ride Height must sum up to a value between -4 and 4. This means you can have, say, 2 on each side to raise the body up a bit, or -1 and 5 the front and rear respectively - either to correct unwanted rake or to make some of your own… But do go easy on that prospect. Visual bins may well be a thing otherwise.
    Chassis tunnel size unrestricted.
    Body Z offset banned.
    Track width allowed.
    Wheelbase offsets allowed to correct wheel arch fitment.
  • Engine: Allowed to fix clearance, not allowed to make the drivetrain look like something it isn’t.

Interiors are not required and will not be judged in this CSR - as usual.




Hey, it’s still the 80s. Whether you still think everything is “radical, man” or if you’re with the program and embrace a more brutal worldview, style is important. Especially in a sports car driven by a young rockstar.


Rob wants his car to be capable, rather than all show and no go. It can be fast in a straight line, or it can be masterful to handle. Could be both, too - but Rob would be happy with one party trick.


You don’t have to be very concerned about specific layouts and all that - the 1980s were a time when many a route to performance was tried, after all. However, you should look at performance cars of the time, what sort of power they made, stuff of the sort - and I guarantee you that you won’t get far with a cleverly cut-rate Lotus Esprit V8 Twin-Turbo just because, say, it nails the performance requirement.



Now, while Rob is willing to spend all of his 14 grand if need be, cheaper is obviously better while the band’s trajectory is uncertain and most of its routine earnings are spent on alcohol. Would it look good if everything fell apart and he had to show up on his dad’s doorstep flat broke save for a shiny sports car?


It would be embarrassing to have the best ride in town but never being able to take it out because it’s sitting in the shop. It would also be damn boring: not only is a flimsy sports car embarrassing, but it’s also something you can’t properly enjoy. No, this thing needs to be built to last.



While Rob does like the idea of a serious out-and-out sports car, it’d be better if the car wasn’t useless. In his busy social life, carrying around people, stuff, or just somebody’s forgotten guitar are realistic concerns.

I will not judge the in-game stat; instead, I will look at door and seat counts, the car’s size, and the shape and size of its supposed cargo areas.

Service Costs

A complex car is one that causes hassle: The mechanics take longer to fix it, and mending it on the side of the road would be a dubious proposition. Rob knows that at least some form of warranty will be offered regardless of what he purchases - but if a car has a reputation for being expensive to fix, it’s because it’s hard to fix, and that wouldn’t sit well with a guy who lacks patience.

Environmental Resistance

Rob would have been fine buying an old Trans Am or something of the sort, but the local weather has ruined most of them - and left the rest expensive. The frontman would prefer his ride to last, even in Illinois.


Thrill-seekers Ruinous Revolt may be, suicidal they are not. A car that’s too hard to drive, park, hoon and so on and so forth is useless to Robert.



Does it need to be said again? Rob is a show-off. And while it’s more important to dazzle people with the car’s looks, he would not want his style cramped by some magazine-reading know-it-all calling his vehicle cheap.

Fuel Economy

The fuel crises are gone for now, but there’s no telling when things might change - and besides, if Rob were to buy a single-digit mileage car Luke would be on his ass asking to “please let his Mother Earth live”.


You know how young people are, they think themselves to be indestructible. However, having driven a half-dead Chevette with a jerky converter lockup, Rob knows that there’s a level of discomfort he simply will not tolerate. Plus, headbanging with a damaged spine isn’t fun.

Note: If a stat or aspect of the car is not listed here, that’s no reason to dump it to salvage the other stats. Eventually - and doubly so for the finals - the cars will be judged holistically, and any shortcomings your cars may have will bubble to the surface. You all have been warned.

Given the MR2, and perhaps to a lesser extent the Fiero, how much ass-n-trash room is Rob really expecting? I’ven’t seen the latter up close, but an MR2 hardly fits my grocery run, let alone band equipment.

I don’t really remember 1987; were custom vans still cool? What about wagons or shooting brakes?

The brief (its less-brief version) is awesome, by the way.

i think that was just another fad that was born and died in the disaster of the 70s, but it would still be an awful idea because:

First of all, thanks!

If need be, Rob could just go the all-out route anyway - at worst, he’d get more of a ribbing from his bandmates. Thing is, if you can go as fast or turn as good in a car that’s not massively impractical, that car will win.

I’m pretty sure that era was when the cool factor of wagons was at its lowest. Hardly better than the minivans that were pressing them in the market.

The bit about the car inspiring his performer persona, which I only got after reading the full story, strikes a chord (pun intended). My own such experiences don’t much apply, though, especially if wagons won’t fly. Yeah… in 1987 they were symbols of the Suburbanite Old Guard. It’d be a few years before the likes of LT1-powered GM and various souped-up Euro wagons. Oh well.

I don’t mean minivans, I mean repurposed cargo vans. At least a sizable contingent of kids in rural Canada in the early 90’s thought the likes of the A-team were pretty radical [sic]. None of them handle, sure, but some of them had an MR2’s passenger volume worth of liters under the hood, which by the late 80’s even the Big 3 Merkins had figured out how to turn into something resembling forward progress. Combined with looks, ability to schlep band equipment… and what for a metal band is a pretty potent trump card: the ability to host groupies for afterparties… makes for good reasons they got popular.

Allowing vans to be viable contenders would make for a less-routine competition; as it is, my proposed entry would be little more than a cheapened version of CW5 (will the wall be updated again?) or a newer version of CSR154.

Yeah, but the competition is not for a band vehicle, but for a personal vehicle that the frontman wants. And it will stay that way.

I know this was in the last challenge and it made sense for the '50s because rear engined cars of that segment weren’t very common, but can we lift this restriction for rear engined cars this time? Front and mid would still be locked out of it for balancing, but currently rear engine is fucked if it uses anything other than wishbone in the rear. To make macs function you have to use minimum a 40 mm difference in tyre staggering, which puts anything less specialized than a 911 out of the question and puts the slightly older 911 designs out completely. Lifting the restriction only on rear engine would make the use of it more viable and more realistic. It would also keep front engined options from gaining an advantage from it, pushing them towards more realistic engineering choices as well.

I think both my CSR155 and TMCC28 entries were 30 mm stagger and ran Macs on all four corners. But in general, Dbl Wishbone rear would make mid/rear engine cars them more accessible.

Yes, but at least in 155, you had much more money to play with to make the weight distribution slider even remotely possible. This round is much, much more budget conscious. And tmcc was literally very small, not very large engined cars where the engine shouldn’t weight very much at all. The fact that you had to stagger the tyres even then proves my point.

I never touched the weight sliders either. For either car.

If anyone wants to see how I made those cars mechanics wise, I can share them. Either in a PM or in a thread.


For CSR155 I had 20 mm of tire stagger, only achieved because cross-plies are shit and massive rear camber, along with weight slider all the way forward and a tiny rackety engine. Most of the engineering went to shifting weight forward to use macpherson struts front and back without making it a deathtrap, and it ended up worse for it - although it being half of a shitpost didn’t help either.

In any case, I support allowing rear double wishbones for rear-engined cars.


I am not 100% sure about a rear DW ban here at all. With some techpool you should be able to even get multilink in 1987 (which also was used by, for example, the Mercedes 190). That generally gives even better stats.


Tbh I’m split on it right now. The biggest advantage of complicated suspensions in general is comfort, and I’ve dialed that down to a 1-star priority - so people may not even want to use those complex suspensions that badly. I will consider my options and get back to you in the morning.

Also, unleaded fuel could as well mean 100 RON Ultimate, that’s a bit unrealistic for the 80s, isn’t it? An octane rating could be welcome.

My suggestion would be a mandate for the use of 91 RON regular unleaded or 95 RON premium unleaded, with the latter potentially subject to a slight penalty.

Also, with TRX tires becoming less common by 1987, tire sizes for this CSR should not be divisible by 10, i.e. the last digit of a tire’s width must not be 0.

Does this mean we can’t use any other body styles? Are trucks and vans out of question entirely?


Sedans and coupes (including hatchback coupes) ought to be preferred.

Also, I just made a pair of test mules for this one - an FR V8 pony car with a live rear axle, and an MR I4 sports car with struts front and rear.

Since this is for the US market, and the previous two CSRs have done it, do we have to use sealed beam headlights + sidemarkers?

The sealed beam mandate was repealed in 1983. FMVSS 108 applies.


In addition to this, pop-up headlights were still common in 1987 - you may use them if they fit the car’s shape.
