Hopefully, I have discovered the cause of the chattering and hoping issues I have been experiencing. One of the rear 8610 dampers (RR) was bad and not functioning on the compression side. Also, I have installed Koni 8611 dampers that will allow me to adjust both rebound and compression. Thank you JohnC, at Beta Motorsports, for the fast service and installation advice. I'll be able to test the new setup, that includes lowering the rear spring from 350 lbs to 325 lbs, next Monday during the Asphalt Ventures track day at VIR. Yahoo.
Alan,
Thanks for the pictures. Now I remember seeing your setup and braces, but it was years ago and at that time I probably didn't know what I was looking at.
