I had the same problem; nice setup, getting in the 212s in laptimes, and
WHACK! Snap oversteer. It was really frustrating coming off of Four on
a hotlap, and ending up backwards on the pit lane. So, to make a short
story shorter, I cranked up the rear wing, and down the front (if you
saw the IRL race at Texas [I was there] you may have noticed speedway
front wings and road course rears) and I did alright. The rear springs
are so soft, I could just see the back sinking like stockers used to at
Daytona.
If you want my race setup, e-mail me and I'll send it.
