Jack, I'm working on a home built rear coil /over car. The outer brackets are fixed for toe and adjustable for camber. The inner brackets are fixed for camber and adjustable for toe. Spax coil overs. The current springs are two inches short. I machined a 1.5-inch spacer to test the spring rate once on road. If good I'll remove and order same rate two inches longer. Do you know what shock, spring rate and length you have? This is the third coil/over through the shop. The first I lost control of at 60/70 mph in curve with a seam across the lane rear bounced and around I went expecting to hit the building. Removed all coil over returned to customer as a rubber car. The second one, first test drive the first to second hard shift it torque steered to the right almost hitting building. Returned to owner with a warning about torque steer. This one I have now has everything rebuilt. I want it to handle and want to hear from anyone with info about spring rates. Thanks Steve (CTR)

I just bought my first Classic Mini. It has a Steelex (sp) Mini Beam on the rear with coilovers. Anybody know anything about this or is there info out there?

Thanks.
