PART NUMBER: 61-4182
These rear upper control arms by AWR have and eccentric bolt in the outer position that allows quick and easy adjustment of rear camber without affecting toe.
AWR starts with a fresh factory rear control arm and modifies them in-house to accommodate adjustable Mazda cam bolts. They are powder-coated in gunmetal gray and come with two sets of eccentric cam bolts.
Bushings are NOT included. Sold as a pair.
We recommend starting with the eccentric bolt in this arm set to the middle, and then haveyour car aligned by adjusting the standard eccentric bolts in the lower/inner arm positions to your desired camber as normal. Following that initial setup, you can then use the eccentric bolt on this arm to make quick trackside adjustments to your camber as needed, and you have room in the range to add or remove camber.
