Lightening up my 2000 GT

[blue00gt]

You can shed the pounds with tubular k-member and control arms, coilover springs, racing seats, fiberglass hood, hollow aluminum sway bars, manual rack. You mostly want to remove weight from the front end as this helps weight transfer on a launch and helps turn-in for cornering.
I believe most of the k-member manufacturers make them for mod-motor cars now, even if alot of the magazine ads don't reflect this yet.
Choice of manufacturer depends on whether you want to build the car for handling or drag racing. Give the fact that you already have Maximum Motorsports parts, I would assume you want handling. I would check out Griggs Racing (the best in my opinion but very expensive), Maximum Motorsports (supposed to release one very soon), or Kenny Brown. Their k-members are not as light as some of the others but are stronger, which is important when you load up the suspension in corners.
