I had the VMC rear control arm kit w/toe links on my old 135, for the money it was a very nice setup. The rear end felt more solid and a bit more positive feedback. Install was a breeze and adjustments were quick and easy; Fit and finish was spot on. Personally I preferred how they use a locking collar versus a jam nut, all I usually needed to adjust the arms was an allen key to loosen the collar, the arms could then be rotated by hand without any additional tools.
The only downside was that the joints were open to the elements, I wish it was possible to get the arms with a boot similar to what the Challenge arms have.
U WOT M8?
