I know uca does front offset bushings but does a company do rear upper? Can I use a ap1 rear upper control arm in my ap2?

 

I believe that the AP1 and AP2 bushings are different, they have different part numbers everywhere. If I recall correctly the AP1 front and rear upper control arm bushings are the same which is why they're offered for the rear of the AP1.

Most of us that are lowered don't have a problem getting enough camber in the rear but if you need more I have some SPC adjustable upper ball joints I could give you a good price on (came with my car and I replaced them so I wouldn't take points in TT).

 

AP2 bushings are softer than AP1.
AP2 rear upper control arms are thicker in bushing dimeter. In AP1's the rear and front upper control arms are the same size.

 

Phase 2 (p2m) makes some decent uppers for the rear. Use them on my race car

 

i was hoping to see if I used ap1 rear uppers I could install the offset bushings for the front into them.

 

It doesn’t look like it. I have an Ap1 and ap2 subframe side by side. The ap2 is about 1” narrower between the a. But you could probably use one with custom made bushing. But as a stock piece with stock bushings no. The outer ball joint is the same though.
