Are there any parts in particular you're hoping to see developed?
I tried getting WC LatheWerkz to make a replacement reverse lockout ring for the BRZ to replace the cheapy plastic stock one, but because of the sheer size of the flaring of the ring's top and bottom it just wouldn't be cost-effective. Perrin made one for the STI, maybe I'll ask them to make one for the BRZ? But without their logo on it, which I doubt they'd do. It's just tacky-looking with their logo on a reverse ring.
