I want to put 4.30 gears in my 87 gxl, I was wondering if I have to do any other mods with it. I have the basic mods already, Iwas just wondering if i should put in a lighter flywheel at the same time. Will the lighter flywheel make that much more of a difference. I know the acceleration is slightly more noticeable, but if I have new gears, which also increases acceleration, is it worth it to put in a lighter flywheel?
