I haven't done any mods to my '05 Comp G that I have planned. But, I have read a TON of stuff on these cars since I got it. I think the best thing to do, like some have said, is get a budget and then compare that to your goals. If they don't match, one of them has to change. Either the budget or your goals. I've also decided that supporting mods are probably the best way to go, even to the point of overkill, before you start dropping pulley sizes. That is, if you want something reliable, which I think we all do.
