<div dir="ltr" data-setdir="false">Hi Todd. I raced a TR-4A years ago, but have driven aggressive TR-3 street cars since college and I still have a TR-2 and a TR-3A today. When I built a TR-3 vintage race car in the late 90's, I followed Kas Kastner's Competition preparation manual. For rear springs I simply added a leaf to the stock springs and for the front, I ordered whatever competition springs were available at the time. Perhaps more important than springs if you want to control body roll is sway bars. It's been a long time, but I believe I used at least a 1" bar in the front. Stealing from sprint car technology, I used a tubular bar that was splined on each end. Then I had aluminum arms made up to slide on the ends of the bar and were made out of 1" by 2" stock. These arms, attached to the suspension with rod ends provided very firm roll stiffness. I mounted the bar to the frame with custom made aluminum brackets - no rubber in the system! I also set up the frame to accommodate a rear bar, if needed. I would put a big front bar on first and try it without a rear bar. If it has a tendency to understeer add a small rear bar and go larger until you find the right balance.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Good luck with your project.</div><div dir="ltr" data-setdir="false"><br></div><div dir="ltr" data-setdir="false">Jack Wheeler<br></div><div><br></div>
