The preferred tires for autocross versus track will be different whether they are R or non-R compounds. You want autocross tires to heat up quickly. For a 20 minute track session your car is both hotter and for longer periods.
- You can make your car and driver pointier car in a safe autocross environment with usually minimal consequences if something goes fairly wrong.
- The job your suspension performs is also different, see bullet #7 in Tunnell's post. If you're not sure what Bob means by "out of phase", ride with a local hot shoe and watch his hands during a slalom - it will seem that (s)he's turning ridiculously early.
That said, for autocross, my factory E36 M brakes have been fine for my minimal setup (suspension, no motor mods) and I would expect the same for my E86 (only autocrossed once so far). If I drove enough track, I would look into something else. |
I realize they are 2 complete things. I'm trying to find a happy medium though, if that makes sense.
I've had my fair share of spins in auto-x from trying to shave time, of course there wasn't sand right next to me, so that helped (well one time there was a curb, but that involved me going sideways through the finish cones, plowing 5 DNF cones...but that was wet anyways).
I will running RS3s, once again it looks like a happy medium. May take 2 runs to get to temp, we'll see. Once I can get tires to temp, I have no problem keeping them there inbetween runs.
There have been a couple times auto-x where I feel like where I should have more brake. Of course that's me being picky.
Here is one of my latest runs, not the greatest thing...but I know what you mean by turning in early:
