Good to have you on here, Marty. Here are 2 other T4 builds.

Jared at North Country Subaru has actually come from dead last to win with his current T4 trim against his competition.
And Ed Barr in the Bert Smith BRZ appealed for less weight but was denied at some point. I don't have any direct contact with either of them, but I'm sure we can get in touch with them if you need additional support to make the case for the car.
