I'm converting the suspension in my '13 track car to Comp Coupe spec. The pics below is the control arms with mono balls installed. SnakeOyl (Viperpartsusa.com) did all the machining work (Thanks guys!)
We are also installing billet rear shock mounts, control arm stud kit. I've already been running their alignment shim kit on my '13 and ACR with great results (My front camber was moving before the shims).
I'll report back next month after my first track event with this setup!
