What do they do and are they worth $80 for my car? Will they lower ets at all?

 

New control arms and bushings will help plant the power to the ground more efficiently... A worthy mod for even a car that's not raced.

 

The rear lower control arms locate the axle assembly front-to-back relative to the body. When you launch, the LCA's are the only thing that pushes your car forward. If they flex, have sloppy bushings, or don't keep the correct angle relative to the ground, you will get a lot of wheel hop, and poor traction.

Is it worth getting new LCA's? or would the poly bushings that came with the ES Hyper-Flex set be good enough until I'm running more HP?
