ITB CGT FAQs

[duandcc_forums at cox.net]

The first suspension mod I would suggest is a 4000 quattro front sway bar. It's quite a bit thicker than stock and kills a LOT of roll. Bolts up to the stock mouting points on your CGT. Then add a rear bar. I haven't BTDT yet, so I cannot comment on their effectiveness. I'm running Boge TurboGad shocks/struts and LOVE them. They are reasonably priced (under $275 per set of 4), 15% stiffer than stock, and have a lifetime warranty (that Boge backs up well, on my 90q I used to replace them every 2 years even if they "looked OK" and Boge never had a problem with it). I've heard good things about H&R springs, but have yet to experience them, I'm rolling on stock springs now.

Also, assuming it's not against regs, have you advanced your timing yet? If you run 91+, you should be able to advance the timing by quite a bit before detonation occurs. Advancing the timing puts a good deal more oomph into the CGT.

Good luck on the track...
