John at Fabspeed was very helpful;,Autoquest in FL, is working both on r & p, and gears for gt4!  The r & p should be ready for market in 2 months and very affordable. Sun plans on installing the r n p.

Gavin at Autoquest is highly knowledgeable and most helpful.  They have hot rod bits for rs and gt3, which Sky may apply to his next rig.

Gavin points out that gt4 has much weaker rear suspension geometry than gt3, which constricts the negative camber build needed in a corner; this issue is not something the dsc controller can resolve.
