oh and with a 4.0 final drive your trans and engine will wear more cause the engine and trans will be spinning faster at any given speed compared to the stock final drive. but as long as you are good about maintenance it should be no prob.

Okay, I'm kind of a maintenance freak with everything done on time. but if it promotes wear faster than usual. .

i wouldnt say it wears more but it can if you are not good about maintenance. with a 4.0 final drive you trans and motor is gonna spin 10% more then normal. and if you are gonna do the final drive you might as well do a limited slip diff.

but just do your research so you wont have to buy parts twice when things dont fit.

Alright. and if I have a sport model don't I have the lsd? or is it the vlsd... lol so much to learn I suppose. thanks for all your help!

z-tube, 5/16 or 1/2in spacer, aftermarket exhust system and a tune to tie mods together. Then you see the gains. Most members dont do aftermarket headers because they are apita to install and the cost vs gain isnt worth wild. As far as drivetrain goes you can add lightweight driveshaft along with a fd gear swap.

And by aftermarket exhaust system. That will include a catback and the cats itself (HFC or test pipes)
