Hi V8 folks -
I'm looking for recommendations to size my torsion bars and rear spring rates. Component-wise, it's an LS3 with Boxster 6-speed. The total drive train weight is around 575 lbs. I'm running Koni yellows (helper springs on the rear), 17mm raised front spindles and the 2" Tangerine rear suspension points and tall shock tower kit. I'd like the ride to be sporty but tolerable. if that means anything! The use case is "spirited street driving" I'm not worried about ultimate track performance - at least not yet. So, wha'cha running? Thanks, Chris Attached thumbnail(s)

This is my LS Car with 901. Boxster S trans is stored for now. Ride is very tolerable, not uncomfortable at all. No twisties yet. (IMG:style_emoticons/default/headbang.gif)
