We've been working on a new upper control arm mount design over here at BMR. Our latest design offers more adjustment than the outgoing design for those of you looking to fine tune your rear suspension even more. They should be hitting the shelves soon, we're just finishing up our first batch of hammertone. We've made some changes to the existing hole locations, and added a third hole to split the difference between the two. We also redesigned the gussets that run the length of the mount. The new design features triangulated gussets that run the length of the mount, vs the rounded gusset on the older style. These changes result in a stronger mount. We never had issues with the old style, but if you're going to improve on something, you might as well make it stronger while you're at it!
