I don't think I would want to cut on a h code car. I WOULD however want killer brakes and any bolt on that would update its 'overall' performance...and a good amount of engine tweaking. Custom wheels for more tire. At the most... I'd might tack in some connectors. But that's it, and... you can cut wheel and grind smooth the witness marks from them if wanna go back. You just don't want it twisting if you get overboard on the power and you don't want to go up and smoke and not be able to use it. Tint the widows, bolt in better seats, stereo
