With the new shop opening soon, we have started preparing our track car to compete again. We now sell SPL Parts, so we decided to upgrade all of the suspension arms and bushings to demonstrate their products. The image shows most of the SPL catalog of parts; upper control arms, lower control arm bushings, front compression rod bushings, rear monoball knuckle bushings, and rear camber / traction / toe arms.

The spherical bearings are very good for the race track, but are very noisy and rough on the street. The car is only used for racing now, so I am looking forward to the more rigid ride quality! The upper control arms allow for very easy caster and camber adjustment, and will allow much more adjustment for alignment settings compared to the factory arms.

Here is the stock front suspension -
