I cannot be fucked to redesign my cars and spruce them up all nice-like at the moment.
So have a +15 tech slider abuse car with an engineering time of like 60 years.
I didn't even bother doing it up, just got a MR body with a nice wheelbase and 395 rear tyres, dropped as large an NA V8 as I could into the bay, pumped as much power out of it as I could without blowing it up, ramped the downforce way up, set the suspension tuning to something that seemed quick, and shat this out:
We're looking at 1264bhp in a car weighing 1035.3kg. It's been a long time since I did anything like this, so probably you can find something a fair bit faster still. Just saying, there's room to move, but I do know quite a few of you aren't interested in going 15+ everywhere, nor do you have to be!
EDIT: had a tinker for another 5 minutes, obviously the gearing could have been optimised and I took a cog out, and adjusted the suspension for maximum cornering:
So now this thing be like Spiderman on meth superglued to rails or some shit:
I dunno, you can probably do a few tenths better still.
