I ditched the TC3 for 2 SSG cars. A total world of differences for me:
-diff access faster
-hing pin the size of ever other car 3mm(AE pins where tiny)
-battery more centralized almost touching the shaft
-Once the Buds bumper was installed breakage was far and few between
-on the track it seemed more consistant from run to run.
-it just plain looked kool
I did add TC3 lower shock hardware to the yok shocks so i could continue using my 9pack of AE springs
