If you're serious about how your car handles, you should upgrade the rear suspension with adjustable control arm links.
There are two major drawbacks to the factory links: (1) You can't lower your car and maintain proper suspension geometry. The factory links create too much toe-in, which cannot be adjusted out, creating handling problems and excessive tire wear. (2) The factory links have rubber bushings, which make handling imprecise, especially in performance driving when suspension loads are highest.
Rennline adjustable control arm links solve both these problems. Manufactured from 6061 aluminum and feature a turnbuckle design that allows each arm to be lengthened or shortened as needed to restore proper suspension geometry on a lowered Porsche. The FK Teflon-lined rod end bearings ensure precision handling and lock in your car's alignment settings, ensuring predictable cornering under all conditions. Unlike the competitors' product, Rennline arms come with eccentric locks and new hardware so you can completely eliminate the factory setup, which is known to go out of adjustment under hard driving and ruin your car's alignment.
