Assetto Corsa Challenge - New round - GTR GT3 on Road America!

Thanks, much appreciated. Time to get studying!

Edit: just looked at the videos side by side. I now realis e that my lines are actually fine, it’s the delay in shifting that’s adding time into my mouse run and to a lesser extent, the wheel run. The wheel run is still slower due to my bad braking, of course.

HOOOOOOOWWWWWWWW

i pretty sure i have done 30+ laps in this track with this car. yet i’m still stuck on the exact 2 minute mark.

ramthecowy · 10 February 2017 00:29

I’ve not cracked a cumulative 15 laps yet. Here’s me doing a lap in the Lotus (with no commentary, sorry). I know I could easily find a second with cleaner driving. @everyone any feedback or suggestions?

Ignore the stupid credits thing, that’s Movie Maker acting up.

So through Slotemakerbocht I know I could make up time, I’m not confident/aggressive enough through the long fast right hander after that and before Scheivlak. I did mess up pretty hard on Audi S and didn’t take a good line through Luyendijkbocht.

As for the actual car setup, it was even tyre pressures everywhere, then front toe was around 10 or 11 (rear untouched), camber in the front was -2.0 and rear was -2.4 (I think?), after that I increased bump and anti-rollbar stiffness in the front and reduced the other one below bump that I can’t remember because it’s 2 am and I’m too tired Handled like a dream, turned in really nicely and doesn’t even have a semblance of understeer. If it does kick the rear end out, all it requires is some throttle modulation and you can just keep pushing. The only thing that I still haven’t gotten used to is the brakes.

And apologies for the terrible shifting. I can’t seem to get a trigger assigned to clutch and I don’t think this car has autoclutch or revmatching or anything.

The autoclutch works, you just have to remember to let off the throttle like you would in real life.

I also don’t have a clutch assigned to anything:
AC will not assign the clutch to anything but the joysticks or my L2/R2 triggers as the game requires it to be mapped to a variable input (not just an on/off button).

I’m now fairly confident in my lines, so here’s what I think:

Your setup seems a little twitchy and understeery (the front camber should be a lot more negative than the rear) to be honest. The track’s slightly bumpy and relies a lot on midcorner grip. I would actually loosen the anti-roll bar on the front and increase the rear bump to make the car turn tighter, you’ll notice a significant increase in confidence in slower corners. The downside of that is that you would be even more prone to oversteer, and I notice you’re getting a bit of that on some crucial corner exits. Maybe this kind of setup suits my own driving style: I’m very aggressive and have to remind myself that smooth driving makes for better times.
In general, you’re probably short shifting slightly. You shouldn’t need to be in 6th on the start finish straight, nor should you need to be in 5th before Audi S.
Tarzanbocht is a near perfect half circle so the apex is pretty much right in the middle of it. It’s also got great camber so the moment you hit the apex you should be able to ramp up the throttle to full. You’ll know you’re making the most of the corner if you nearly run wide of the kerb (use the whole road). So I would say while your timing was not bad you can put more throttle sooner. Apex corner speed was nearly right on so your braking is probably mostly fine.
Gerlacht is difficult. It’s blind, it’s over a crest, there’s a hint of bad camber. Your aim is to try and get the nose of the car almost touching the inside kerb. If you look at my video the apex speed is more like 115, which is a huge difference, but of course since Hugenholtz follows it won’t gain you more than a few tenths.
Hugenholtz is interesting. Again a good camber but particular because the following section is long and high speed you want to maximise exit speed, so a slow in fast out approach is best. I found the line that starts a bit more on the outside and lets your nose track towards but not quite hit the kerb nearer the end of the corner lets you make the apex a bit earlier so you can get on the throttle sooner. But you could still probably brake a little later and go a tad deeper into it.
You can keep it pinned through Rob Slotmaker. By the time you get to Sheivlak you should be doing at least 188. Der Bayer is doing 192 but that’s because I have a gap between shifting for clutch and he doesn’t, for that reason I don’t bother shifting to 5th. The difference is that subtle.
Your line through Sheivlak is nearly perfect. If your car was set up for a bit more grip mid corner you could be pushing 135 around the inside kerb, and keep the throttle pinned. Of course I should remind myself that speed at the apex isn’t that valuable as ultimately once you reach the outside kerb you should be going the same speed anyway.
I find Malboro one of the hardest corners to judge. You can risk cutting over the kerb a little but it’s very bumpy and you’ll either oversteer or lose grip. The trick is to hit the kerb without going over that island thing beside it, because those islands are really steep or something. I would aim for an apex speed of about 124, for that, you have to set yourself up perfectly on the maximum outside for corner entry, made all the more difficult by that left kink right before it. But the moment you pass the kerb, as soon as all four wheels feel planted on the road, you can just floor it in 3rd until you’re about to bounce off the rev limiter and that’s when you should brake hard for Corners 9, 10 (Renault, Vodafone)
Renault and Vodafone I consider the most annoying bit because the apices on both corners come quite late and they’re tight so it’s blind and you can’t really judge them except by memory. Again, slow in fast out helps, you’ll know you’ve picked the right apex for Vodafone when you’re almost touching the inside kerb and then on full throttle the car nearly pushes onto the outside kerb.
As you know you dove into Audi S too early, I find you can get away with a touch of late braking here as so long as you ease up on the brake pressure while turning in, you can continue to slow down in second over the entry. Fujiwara-esque pro-tip: The exit depends on your entry but once you do get the entry right you’ll find that you can achieve a slightly faster turn in by floating the left wheels over the left kerb (it’s more slippery so you’ll have relative grip on the right), so you can keep the steering more neutral while accelerating hard. Having the entire car off the road will negatively affect all your grip plus its bumpy so it’ll force you wide and slow you down.
Kumho was not bad. Aim for a speed of at least 120 when your left wheels barely touch the kerb on the exit. That kerb appears to be cambered, so it’s okay for you to hit it despite what I said earlier, but of course it’s right next to sand runoff so the margin for error is low!
You’re right about Luyendijk, again having said about touching the kerb at the exit to Kumho, if you pick the right line (this is one where you have to aggressively seek the inside lest you drift to the outside… but only in a manner that allows you to turn at a constant rate), you should be able to keep the throttle pinned and exit doing close to 170 by the time you hit the outside kerb.

EDIT: I can’t change my settings with the G27 to accept auto clutch with a shifter, all I do is burn out the clutch so with that I resolved to improve my braking and shift even faster. The fruit of my efforts is getting close to target time. This will be the time I actually submit as an attempt, not the mouse + ABS one.

koolkei · 10 February 2017 08:49

Nope. The s3 one is the other trim with higher power right? Yeah, not that

ramthecowy · 10 February 2017 08:50

Yeah you might want to use that, we’re all using that one.

koolkei · 10 February 2017 08:53

Right… 40 laps on, and i discovered that i have been using the wrong car.

GG me…

But the fact that i’m less than 1 sec slower that you ram… Hehehee

strop · 10 February 2017 10:02

I reckon you’d be able to get quite fast with the S3. It’s just a tad prone to oversteer if you power too hard out of the corner, but only a bit.

I did a quick test with the stock 240R, you’d be shooting for a 1:58, so by that reasoning, you should be able to push at or even below 1:57 with the S3.

ramthecowy · 10 February 2017 10:03

How in the fuckin world are you so quick on keyboard?

strop · 10 February 2017 10:25

…huh?

I forgot Koolkei was using keyboard, what is this sorcery

MarcoAlla · 10 February 2017 13:58

First run, i love both Track and car, but i’m a bit struggling with understeer… I will try to change the setup to reduce understeer on corner entry.

@Der_Bayer nice driving! we have similar time, but completly different driving style.

squidhead · 10 February 2017 15:48

If there ever was a time I missed Larry, this is it. I got no visual idea on my braking zone for second half of the circuit, and the car isn’t making it easy on me either. I will not be attempting this again…

TrackpadUser · 11 February 2017 04:17

Some progress

koolkei · 11 February 2017 04:33

close enough?

i also haven’t tried much suspension tuning, there’s definitely some time left could be gained by tuning.

so much laps though

i’m fast, but not consistently fast…

here’s the full raw footage if anyone is even curious how i drive with keyboards for a long time

i also did it again, to ALMOST get a 1:56.7 only to crash at the very last turn. FUCK THAT SHIT

strop · 12 February 2017 12:50

btw there’s an Agera 1:One mod out there, and it includes… the unique British TUNED #5 chassis that upgraded the turbo so it now puts out 1450hp… let’s just say in case you were wondering why there are as yet no record laps of Koenigseggs around, say, Nordschleife, try punting one of those around the course (hint: if you can actually string together a clean lap it’s well up for a lap in the 6:30s).

I mean case in point the one time they tried so far (with the 1360hp version) it suffered an ABS failure heading into Adanauer Forst, locked up and slid straight into the Armco at 100mph.

This is… a good point of reference for imagining what it’d be like to drive a GG car flat out…

koolkei · 13 February 2017 05:30

##did i mentioned that i finally got 1:56.7?

strop · 13 February 2017 05:45

how do you change the rate at which the steering wheel returns to center? When I tried it kept coming back way too fast and I couldn’t hold any kind of lock.

Also, shall we start voting for the next round? I think FindRED11’s suggestion of using a Cobra sounded like fun.

koolkei · 13 February 2017 05:49

this is my keyboard setting for the track

some tracks may need small adjustments, but usually these setting is enough.

Matti · 14 February 2017 00:01

Soooo… is a automatic slushbox allowed? (don’t judge me)

Edit: Oh sweet.
Saturday: 2.08.xxx
Sunday: 2.00.xxx
Today: 1.57.998
ABS on, TC off, Automatic gearbox w/ manual downshifts. A Logitech Dual Action gamepad. However, I don’t know how to set up this damn thing. I am used to accelerator/brakes on left pad and steering on right. But I can’t change that on the xbox controller preset, nor I can change the steering speed on ‘‘custom’’.
