To top things off we had one of our handy friends, Scott Higashi, whip us up a set of decidedly un-pillow like pillow ball mounts. The OEM suspension simply uses an overly large hole in the upper mount with rubber isolators between the bolt and the mount. This, unfortunately, allows the spring to move a little independently of the shock, and adds some unwanted squish that was not controlled by the dampers. Scott’s mounts use spherical bearings to allow the shock shaft to move freely while providing zero slop. Perfect for our racecar.

With no after market options for a front anti-roll bar, we had no choice but to keep the stock unit with the previously mentioned endlinks. Our rear anti-roll bar choice was an easy one as there is only one option to replace the ridiculously thin bar: Addco. The Addco unit is a 7/8” non adjustable bar and makes the car surprisingly neutral with a slight tendency towards understeer with our current spring weights.
We also ditched the flimsy stock rear end links in favor of some spherical bearings. Since no one makes a spherical bearing replacement kit for the P10 with stock or aftermarket anti-roll bars, we had to make our own. We ordered some 7/16” ID spherical rod ends and went to the local Big Orange High Performance Super Store – AKA The Home Depot – to get some threaded rod compatible with our rod ends. Cut the threaded rod to size, tighten the rod end down with a nut, install on the car and you’re done.
The front anti-roll bar will need to have a tab welded on in order to use a spherical bearing endlink design. We will try this ourselves with our trusty MIG welder later, but if you don’t have a welder just about any reputable shop can do this for you.
