I'm thinking along the same lines... I rarely use the audio system, usually when I'm stuck in Atlanta traffic, but when I want to use it I want it to sound OK at least. I plan on reducing weight in other areas, so the overall weight shouldn't change.
Took delivery on 10/19 and i immediately installed the quicksilver exhaust, track pads and braided lines. I have on order harness bar ,belts,silicone hoses and fire ext. I also had my first track session this weekend . I will post under track this week. alot of fun.
