my 96 mark 8 is almost stock, all ive done is remove air silencers, and modified stock exhaust, it has coil springs. i want to spend about $300 on it this christmas. i could get some 4:10 gears and install them for $100 but i dont think i should til i can get an aluminum driveshaft. im only interested in performance upgrades right now. i will do the looks and audio upgrades late. any suggestions ?
