Since those arms are aluminum, they will fatigue and fail very quickly. Again as UK guy found out.
- Surface area limited - irrelevant since the bearing isn't loaded axially. This arm is loaded in compression under vehicle acceleration or tension under braking.
- The loaded surface is actually the width of the white plastic, not just the centre of it.
- EPS may be correct in saying that their product is longer lasting, but without testing data, they can't technically make that claim.
Every. Single. Time. You buy an aftermarket part ask yourself... how many hours did Porsche's engineers spend designing, testing, and optimizing this part? These are professional automotive/mechanical engineers whose life's work is to make those suspension arms, etc. and they put their reputation/job on the line if they send crap out the door since warranty costs can be huge. If it was that simple to improve the part, why wouldn't the engineer have sent the car from the factory like that?
Swapping parts on your car for aftermarket may not always be an improvement.
