Neil looks like you changed the top shock mount design?
Are the upright also modified? The upper ball joint is also flipped.
Yes I have shortened the shocks buy 1 inch as we had to much travel for racing
The ball joint is now a spherical joint mounted in a new chromemoly top A-arm as we had 2 inches wheel deflection from the top arms under acceleration to braking and this movement would coil bind the springs 600lbs under acceleration this was with the billit a arms now I have no deflection.
Trust me when I say it was frightening when you changed gear at 150 mph in a corner and it would jump across the track 10 feet:eek
I have also removed the rear cross brace and made an new chromemoly tube one that picks up all top a-arm bolts from the inner side so it triangulates between both side like a roll cage for the top A-arms.
:cheers
