Double Venom suspension question

[dvcobra]

Curt, you said you are running QA1 coilovers 500lb in the front. Do you have a part number? Are they adjustable?. I also noticed that you have run at Willow Springs, I will be there on May 9 & 10 for the COCOA event if your interested in joining us. Do you know what kind of times you were running out there with your setup?
I was out there last week and I still am experiencing a lot of body role and the back end wants to come around when I push it too hard. Do you think changing from the Carrera 350lb coilovers to the 500 lb. will eliminate some of the body roll and keep the back end on track?
The boxed lower control arms and heavier rear springs helped with the body roll, but I still need less roll I think.
I was amazed to hear that the FFR Challenge cars are using 700lb springs in front and 500lb springs in rear! Is that because of the 3-link and different front style suspension?

DV, I am not disputing your accomplishments - You are the Man! There are many race cars and some street cars that run big springs and no sway bar. 1.73 on the skid pad! There has to be a whole lot more to it than just removing a sway bar. That is obviosuly a full on race car. An ACR Viper, which I would classify as a borderline race car, can only pull 1.08g per Car and Driver. Enzo Ferrari - 1.01. I suspect dv's car falls in line with the street driven occaisional track car like mine. Apples & Oranges?

Lots of body roll and oversteer is screaming for higher front spring and or sway bar rates PERIOD.
Don't take my work for it. See what the Sports Car Club of America (SCCA) Tuning Guide recommends. http://www.wtrscca.org/tech.htm

DV, to anwer your question, I like 500lb springs in the front (with the front sway bar). This coupled with bilstein 250lb coilovers (mounted straight up) in the rear and a .70 rear sway bar seems to keep the car in a neutral to slight understeer condition.

DV, Summer has come and gone. Any more thought's on a custom front sway bar?
