My hardest habits to break are being TOO smooth/letting the wheel slide through my hands when coming back to autocross.
I guess what i'm trying to say is that....i'm too much of a puss when it comes to being aggressive.
However, once I get a run or two in, go look at the timing board and see that i'm being beat by HS Integras or whatever.....I use the anger to drop a couple seconds on my 3rd, 4th and 5th+ runs.
Sadly, now that i've "completed" the car with the front K-member, I haven't really put alot of time beind the wheel to really take advantage of the grip I bought
. My last outtings I kept throwing the car into turns/late braking and the front just wanted to keep gripping and holding the line(within reality).
Of course, all my ramblings probably only apply to those using a GREAT street tire or R-comp's. I'm betting the linear/smooth would apply more if you're using some BFG KDW's or random 300+ treadwear tire.
Good luck, and enjoy your 5 minutes of seat time.
