Hi Todd.=C2=A0 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.=C2=A0 =
When I built a TR-3 vintage race car in the late 90's, I followed Kas Kastn=
er's Competition preparation manual.=C2=A0 For rear springs I simply added =
a leaf to the stock springs and for the front, I ordered whatever competiti=
on springs were available at the time.=C2=A0 Perhaps more important than sp=
rings if you want to control body roll is sway bars.=C2=A0 It's been a long=
time, but I believe I used at least a 1" bar in the front.=C2=A0 Stealing =
from sprint car technology, I used a tubular bar that was splined on each e=
nd.=C2=A0 Then I had aluminum arms made up to slide on the ends of the bar =
and were made out of 1" by 2" stock.=C2=A0 These arms, attached to the susp=
ension with rod ends provided very firm roll stiffness.=C2=A0 I mounted the=
bar to the frame with custom made aluminum brackets - no rubber in the sys=

=A0 I would put a big front bar on first and try it without a rear bar.=C2=

Good luck with your project.
