Having recently bought a higher mileage 2001 Boxster S I've been replacing suspension bits. New control arm links eliminated the low speed knocking both front and back. A local supplier talked me into buying OCAP front control (coffin) arms. I installed them and the ride was harsh with lots of kickback through the steering. Handling just didn't feel right. Not the refined fluidity expected of the Boxster. Ordered Meyle lower control arms from Pelican, just installed them and me and my car are breathing a sigh of relief. Everything feels great. So, I'm putting this out there for all who wonder if there is a difference. OH YES! Expensive lesson. The castings look identical, but obviously Meyle has tuned the bushings properly, whereas OCAP has not. In the picture, the OCAP arm is on the left.
