So i had a couple questions on what i should do to the rear end on this 88 coupe. I want a solid rear end to be able to launch quick nd with less tire spin, i came down to wanting to switch from 28 spline to 31 to be on the safe side cause later i wanna add power to be supported, so therefore i want to do that. Also would it be good for the 31 spline to be 5 lug or 4? Or doesnt matter really? As for gears i wanted to add 4.10, but i would need some recomends on good differentials. Should i add control arms as well? I looked around and asked if i ahould but i was told they dont help out a whole lot so whats the use. Getting some good set of hoosier slicks as well for the wheelspin. Lastly, i want to add nitrious. Car is just about stock. Completely. Has good suspension, engine is healthy stil runs strong and low mileage. I know i would need some supports to add so please help me out, need some options. Thanks!
