Hi guys,

I know this topic has been discussed before, and yes i searched the topic before but i am not getting the right answers.

Is there a significant geometry difference between Ap1 and Ap2 rear ends?

I say rear ends because i know the subframe, upper arm and knuckles have different part numbers for the Ap2 vs Ap1.

But i am not sure what is different. I have heard rumors that the Ap2 rear subframe is stiffer but am not sure if the geometry is different as wlel.

I currently run an Ap1 setup with the bump steer kit, and am wondering if its worth the upgrade to a complete Ap2 rear end.

Has anyone upgraded and felt a significant difference? I run a full on caged race car so even 1 second around the track is meaningful.

Thanks
