As a few others have already said, the 2nd Gen already features drastically improved geometry compared to the 1st gen cars. Our new Hotchkis 2nd Gen Lower A-Arms feature repositioned ball joints for increased caster and improved camber curve. Our arms also have a CNC cut billet spring cup that's integrated into the structure of the arm and fully TIG welded for improved rigidity to prevent deflection.
Hotchkis 2nd gen Tubular Upper A-Arms increase caster and camber gain and the offset cross-shaft allows increased static negative camber without a large alignment shim stack.
Here's a video of an '80 T/A with all our parts (TVS, Subframe Connectors and Upper/Lower A-Arms) in action during testing at California Speedway.
