I modified a GT6 rear spring to remove the shortest leaf and added a parallel main leaf that is thicker than the original main leaf and adds about 40 percent stiffness to the stack. (Don't ask me for the final spring rate, because I have not measured it). But it is very stiff and keeps up with the 450 pound front springs very nicely. I added a 5/8" rear sway bar made from a front bar and it handles with pretty neutral response (no noticeable understeer or oversteer) I do use a 5/8" front bar with the heavy springs.
The rear spring is clamped firmly to the diff and since I did the current setup, I have not noticed the wheel lift that I once had. Right now I am working on replacing the diff with a Dana 36 from a late model Vette. I will be using 3.54 gears but because the cost of this transformation, I won't be able to do coil-over shocks right away. So I will need to figure out how to secure the spring since the Vette pumpkin doesn't have a saddle for the spring. I am toying with the idea of adding a perch onto my Shock mount bracket and reinforcing it.

It seems to work very well now and I did have trouble lifting a leg with an Addco roll bar and the early spring. I have never tried the camber compensator shown in the competition manual that hooks up to the diff if that is the other option being discussed. I have heard that it works well from others. I think I may have used the swing spring when I switched to a later 455 diff and Rotoflex as an experiment to see how it would run after talking it over with a few guys. Not sure if I ever tried the early spring with the Rotoflex. I have Koni's front and rear with Triumph Tune front springs so the suspension is real stiff. This set up for sure keeps the rear wheels on the pavement which was my primary concern and in autocross you really never get out of 2nd gear. As a disclaimer I do not claim to be an expert on suspension, just a part time autocrosser trying to get an edge. I am using a similar set up on a GT6 I am building (also a 70) so if I am doing something real wrong it would be a good time to rethink that one before the tub goes on in a month or so. The GT6 will have a few more horses than the Spitfire and I may try to get this one on the track. Cheers, Darrell *** http://www.team.net/the-local *** Your messages not reaching the list?
