1964 Corvette Coupe

[FLYNAVY53]

Mocking up the new Global West offset rear trailing arms. The advantage of these is the inboard offset allows you to run a slightly wider tire. Additionally, they move the e-brake cable inboard, to prevent the mounting bracket from rubbing on a wider than factory tire. They're also significantly beefier than the factory pieces. The last advantage of the Global West arms are the Teflon lined spherical bearing that allows the swing arm to move through the suspension arch without bind. The result makes it easier to tune the suspension because the spring rate is not being affected due to bind.

The last two pictures show the shim mock up. 1963-1964 shims had holes in the forward portion of the shim. This made it very time consuming to adjust and change out shims as the pivot bolt would have to be removed and rethreaded through the whole stack with each change during alignment. In the pictures, I've changed to the 1965 and later, slotted stainless steel shims and hardware. These are slotted in the front, so that you can slide them in and out of the pockets without completely removing the mounting bolt. They have a smaller hole in the rear which aligns with the small hole I drilled through the frame pocket. This allows the use of a 2" long stainless cotter pin to retain the shims. Once the suspension is aligned, and the trailing arm retaining bolt is properly torqued, tension SHOULD retain the shims in the pocket. The cotter pin is really just added security that they don't back out over time. This is the factory configuration on the 1965 and later disc brake cars.
