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)

I don't know what size springs you have now, but I have a set of almost new 225# springs you can try on for size/have. I don't know if you saw my post in your other thread, but with my Koni Sports I had to have a machinist cut new grooves in the body of the shock to get my rear end down. I will be in Petaluma this afternoon. I can drop them off.
