Thanks a lot! I appreciate you answering all the questions put to you!
I also thought about getting a second servo mount brace to cut into two then having all options from one-piece, two piece or without a brace on the steering posts at all.
Is it possible to modify TC6.2 rear hub carriers instead of using BD7-parts?
I'll be completely honest with you, I basically worked right past the parts that the setup didn't use so I don't know the exact differences with geometry. I lucked out a bit with my timing and was able to build my car with a setup that has already been proven to work well and I just copied it exactly.
That being said I have also seen plenty of 6.2's with kit geometry work extremely well, so both ways can definitely work just fine for those that don't want to switch out to the older parts.
Get a second CF servo mount piece and cut it up, I can get you a closer pic of how I cut mine if you'd like. Just another tuning option!
