TM Autosports reached out to us for a solution on the Gen 5 Camaro. Evidently, the rear knuckle bushings were changed to "NLA" (No Longer Available) by GM in 2025.

Like many OEMs, they also wanted to sell the entire knuckle assembly rather than the bushings themselves. Typically this is because the bushings have asymmetric design(s) and/or are chemically bonded to the bore, something that can be challenging to ensure compliance with in 3rd party part installs.

We went ahead and also created adjustable toe and traction/trailing arms as well, which should go a long way to improve the rear suspension's performance, namely preventing wheel hop and bump steer due to the bushing compliance (aka compliance steer).

Made in Texas, using aluminum billets from Pennsylvania, by car enthusiasts, so that we can build more race cars.

It’s not the easy way, or the cheap way, but it’s how we’re doing it.

Behind the scenes testing of the BMW E9X OEM rear trailing arm. People would be surprised at how flexible some of these arms are …

This also is mounted to rubber bushings, which under hard braking can give a combined deflection over 5-6mm.

Just tore down the engine on our ND Miata development car after the charge cooler on the supercharger sprung a leak and hydrolocked the motor.

The engine is in remarkably good shape despite being exclusively raced in MX5 Cup and now supercharged in NASA TT4.

It’s always interesting to take apart modern engines and see all of the engineering and technology progression in them. The piston design, cracked rods, lack of ring drag, and all sorts of little details all add up.

Was awesome to meet over a hundred people from our dealer network, vendors, and customers in person! Had a lot of good feedback, ideas, and new contacts.
