[Cobra #42]

Steve, Have you checked the surface you are doing these measurements from ?? It must be perfectly level or you can't depend on these numbers at all. I am puzzeled with these numbers, why is the RR 69lbs heaver than the LR (maybe a battery) but usually the entire left side is heaver than the right due to the driver. Try weighing without the driver and send me some numbers. Your front to back numbers are not bad, but you need to work on the cross weights. This car will probably turn great one way , and understeer the other way. With the RR weighing 69 lbs heaver on one side it may have an strong oversteer in one direction and not in the other. If you are going to do any road course work I would like to see the numbers a lot closer. Also check the ride height of the entire vehicle. What is your weight ?? Corner weighting a car requires some trial and error, and to answer your question about spring perches and how much . You can move weight by raising and lowering the corners but only to fine tune the car. We need to move some major weight around before starting to jack with the springs. Maybe you left a big bag of money in the trunk on the RR.
