The angled ballstud mount and top plate angles the bellcranks and steering rack to work in a better window with the recent change in chassis kickup (started with the B6.4). This means that through the arc of the steering and travel of the suspension the relationship between the inner and outer steering link ballstuds are in a more optimal position. This results in a smoother and more predictable steering feel through the full steering throw. It can be a racer preference; you will have to try and see if you like how it make the buggy performs.

This part fits the following vehicles:
RC10SC6.4
RC10T6.4
