yes you can just do the 4:10 swap, however the torque multiplication will amplify the wheel hop (in theory)i did some research on the cost of having bushings installed and its about 800 dollars so i was wondering if its a bad idea to put the 4.10 gears in w/o a bushing kit and maybe just with an irs brace. atleast for a little while. i dont really launch the car so im not sure what i can do. i really want to get some AFS wheels for it but i dont think ill be able too with the bushing kit. whats your input on it guys?
If you read the article on Full Tilt Boogie Racing Homepage they attribute most if not all the breakage to wheel hop. if you're careful to not stay in the throttle while it's hopping you shouldn't have to much to worry about.i guess what im trying to ask is do i really need bushings to put my 4.10 in and if i dont would i have to worry more about breaking IRS?
