So, i went to the track this friday and was spinning like mad. I got some decent #'s ([email protected]) but my 60ft's tell me that there is alot left in the car (2.1 60ft). My problem is that as soon as the boost comes on, the rears begin to spin wildly. I now realize that the tires i got for my new rims are not sticky at all (Nitto NT555 in 275/35 18 format) I want to go with a set of DR's for my stock rims to run at the track. But, i don't want to go breaking any halfshats with my IRS either.
My understanding is that with a big gear (4.10's, 4.30's) and DR's or slicks, there is a good chance of breaking the shafts, but what about DR's and 3.55's??? Any help would be appreciated. I really want to see 11's. My last resort is going to be to go back to a solid axle setup.... something i don't want to do as i was planning to run my car on a roadcourse
