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)

Hey Chris,
A little late to the game. I'm at 22 and 250# I'm 2550# if that makes a difference. Tolerable ride with good handling. |

Tolerable ride with good handling. @dan10101 Dan - No worries, thanks for the input. With the 930 box, your car is a good match for mine, weight-wise. I'm going to start with 21 and 225 and adjust as needed. Thanks again! |
