Control Arms and Camber

The rear control arms of your Subaru are responsible for maintaining the camber angle of the rear wheels, which determines how much of the contact patch of your rear tires is on the pavement. When the camber is off the tires ride on their outside or inside edge, causing uneven wear and early replacements. If tire alignment is off enough then you can also experience steering problems, especially during a turn.

One of the leading causes of that thrown wheel alignment are worn rubber control arm bushings that make a weak connection between the frame, control arms, and wheels.

Replace or Upgrade?

When you have to replace those original bushings, that will eventually wear out, you can choose more rubber bushings, but if you want a longer-lasting solution that will better hold wheel alignment then SuperPro's polyurethane rear control arm bushings are a great option.

Polyurethane bushings are a more durable material that resists the alignment changing force that wears rubber bushings down. Besides wear, rubber bushings also succumb to heat, road grime, and road salts, which will eventually devour them. The sudden and extreme changes in weather that we 'enjoy' here around Stephenville, Texas (plus the need to take our vehicles off road) can shorten a rubber bushing's lifespan considerably. SuperPro carries one of the best lifetime warranties in the business on their polyurethane bushings, including off-road and racing applications.

Driving vs. Driving

The biggest complaint about polyurethane bushings vs. rubber is the increase in noise and vibration transferred from the road to the driver. If you measure the massive increase in performance and durability against the decrease in comfort the gains really outweigh the losses. Make no mistake, these are performance parts probably best suited for drivers who enjoy aggressive cornering, but they won't rattle the teeth of a daily driver either.

SuperPro is an Australian performance brand with roots in track car racing, and they take their reputation very seriously. These rear control arm bushings are meticulously designed to provide the best balance between performance, durability, and comfort for your Subaru.
