So I have adjustable arms on my car now because NASA-TT4 seems like it will have a more open rule-set than NASA-TTD/C, and it seems like a good power to weight class for my S14 with stock SR.

The front tension rods seem pretty basic, I left those as close as I could to the factory arm lengths. In road racing with a manual rack, is there any reason to deviate from that?

Rear camber and toe arms are pretty straight forward. The rear traction arm length I know very little about. - I understand that the factory S14 rear geometry will gain both negative camber, and toe-in under compression. So now for the main two questions I have:


What effect does lengthening the rear traction arm have on camber gain / loss. Same for toe-in/out?

What effect does shortening the rear traction arm have on camber gain / loss. Same for toe-in/out?


Thanks guys!
