IT's actually all in the susp. work with the low 11 sec bolt on cars. They only weigh 2900-3100 lbs and their susp. is probably worth 2-3gs alone. So don't expect to do it with the stock susp, or just some eibach pro kit. Those cars are pretty much race only cars that are gutted to hell and back. Now an 11.8-12.2 bolt on car now thats a normal street car with some weight reduction and all bolt ons ofcourse.

 

Your right to a certain extent, but ive got round $1500 in my suspension with a 98 that has 127k, never had a valve cover off, and ran 11.40 with a 1.47 60ft time. Car weighs roughly 3200 with me in it, so its pretty light. The point is is that LS1's should have NO problem running 11's without a cam much less with one.

 

dont worry bout the rear, i'm leavin off the line with 125 shot, ET streets, and 3:42's that whine from the previous owner not shimming them right and i haven't blown it up yet or the tranny for that matter....KNOCK ON WOOD.

 

dont you also have a 9" as part of your suspension
