replaced upper and lower control arms with tubular arms and heim joints. these are adjustable. did the same with the front sway bar. it has some adjustment to it.
I built PBR calipers front and rear with 12-inch vented rotors for well under 1000 dollars. I used all new parts. I have read that Archer brothers use PBR calipers for their race car as an upgrade.
I did things a little different. I got a new control arm and installed threaded upper ball joints from a dodge. from different race suppliers you can get different lengths ball joints.
