That M3 is an odd car. I like it. I like it a lot. I like that it's light and lively. I like the good brakes, but something it just kills me. Nowhere any good at top speed compared to the rest of the cars and because of the good brakes, the car tricks me in thinking I'm safe braking late and then bites my head off by locking up the front or missing the apex completely. I tried moving the brake balance backwards, but then the rear started kicking out under braking, which IMO is worst then front wheels locking up. And because it's light, I have issues with it, controlling the weight distribution under braking and cornering. I sometimes go thru an S-turn flawlessly and sometimes I just fly one side to the other in it. It is drivable, once you've found your balance with it, and I really do like it, but I can't get under 1:52.- with it.
Maybe I should try the Sierra or Rover ? Tried the M6 and I hated it. Weak brakes, only 5 gears, slow in corners, no real downforce ... and the list goes on and on. Tried the Holden and I got no opinion about it. It's just fast and heavy. Good and bad. I don't like it, but I don't hate it either.
Anyways, about the FPS issue, turned out I do run at 110-120 when I'm alone in the dark @ Montreal '88. Gonna give it a try with full grid and see how it works, but anything over 20 FPS for me is drivable
