Carl, how the hell am I going to get my car to where I am content with driving it, when you keep coming up with these incredible over engineered "must have items". I started with your upgraded heater valve, then installed the solid steering bushings, then bought the aux electric fan, and then got your upgraded A-arms and I have to admit, I am more than happy with everyone one of your items I've installed.

Just back from a 2500 km trip to the Nordschleife with my car. Ten laps on the circuit and all your suspension, brake and general performance upgrade parts worked really well. Thanks a lot for your effort! Its such a comfortable rocket to drive. Jan Frost U
Got the late-86+ upper control arms on Friday and installed them on Saturday. Your product is really nice. Install was easy. The handling feel seems noticeably improved, too. Thanks again - I look forward to doing more business in the future. Dave W
Regarding turn-in, I found this to be GREATLY improved by installing the steel upper A-Arms which Carl sells. They are also lighter than factory and really make it far more connected. Colin J
Application: Porsche® 928 1986.5 - 95 all
Background: Porsche® changed from cast to forged upper A Arms in late '86 and the new upper arms were not designed to be serviceable. When your upper ball-joint wears out, they cannot be rebuilt. We do have a few professionally re-manufactured units at $419.00 each. This part is also still available (for the moment) from Porsche® and the suggested retail price on that is $926.00 EACH. You need two.
Description: Now 928 Motorsports offers an all-new replacement for the 928 lover - our Late-Model Steel Upper-A-Arm. Using the same techniques we use for race car suspensions, we created a jig with the exact dimensions of the Porsche® 928 arm, and have produced an all-steel welded unit with a high-grade greaseable ball joint in it. This is a bolt-in piece that requires no modification to your 928, and it is serviceable if need be at any time in the future.
Performance: The spherical ball joint we use provides more accurate placement of the top spindle than the common production ball-socket joint, and the solid bushings at the rear guarantee exact camber adjustment without the variables caused by the stock rubber bushings. These even out-perform a stock a-arm fitted with with polyurethane bushings, yet move with less effort through the suspension arc . Weight savings = 1.2 lbs of unsprung weight per side.
928 Motorsports Quality: Our part features a steel crossbar, oil-impregnated bronze bushings, and zirk fittings at the back. At the front, it's equipped with a premium removable and rebuildable ball joint for accurate camber placement and long life. The ball joint can be unscrewed and replaced completely without removing the A-arm. Silicone dust boots included.
Price is per PAIR, enough for both sides of one car.
