Recently I bought a set of the popular offset control arm bushings for our cars, but after install and reading some reviews online, I decided to make my own set. The parts I bought were very loose to the control arm inner diameter and could be easily pressed in by hand. While this makes install easy, it is not ideal for on road/track use. The bushings should be properly pressed in and not have any slop. Other users online started to notice that the bushings began to wallow out and have slop in the upper control arm, while others were having too much stiction to the mounts.
This led me to make my own set of both bushings and inner sleeves. What I found was that a harder press (achieved by tighter tolerances) made a big difference to these parts. The inner sleeve should also be properly pressed into the ID of the bushing in order to not develop play. They should not be installed by sliding them into the control arm and then installing on the car.
NASA rule changes also forced me into the upgrade. I used to have lower offset ball joints for additional camber, but that is now a points hit for TT5/ST5. The upper control arm bushings are class legal (with no points hit), while also giving additional wheel/fender clearance.
I am making a few sets for friends so I figured I would open it up for a group buy, much like I did for the Baero BBK (which was SOLD OUT and a big hit!).
If 10 people were to join, price would be $175 a set.
If 15 people were to join, price would be $150 a set.
UPDATE: Parts are now available to order!
