Features & Product Details

Cusco is one of the pioneering companies based out of Japan that has invested countless hours of research, design, and engineering to develop quality suspension and performance products that will improve your driving experience. Some of the fasted cars around the world who compete in time attack, time trials, and other racing avenues will more than likely have a Cusco product on their car.

These are the Cusco Rear Pillow Ball Upper Mounts. These have been designed to allow the user to have more camber adjustment for your rear suspension setup. These are made from 6mm aircraft grade aluminum materials and will come powder-coated in Cusco's flagship blue color. Once installed, they will help control unwanted forces under acceleration and braking. 

These will usually fit most coilover setups that don't come with top hats. You have to make sure that you use the same nut that either came with the shaft of the strut, or use a nut with the same thread pitch. These top hats will come with M12 X 1.25 nuts for the top hat stud, and you can use it as long as it matches the thread pitch on the coilover shaft you are using. Otherwise, use the correct nut. 

Note:: In order to fit these rear Adjustable Camber Pillowball mounts onto a Cusco Zero1, Zer2E, or Zero2R, you must purchase additional parts from Cusco (nuts).

Cusco Rear Pillow Ball Upper Mounts ( Part Number: 658 420 A)
On 06 STi /w KW V3's 4 years ago
4out of 5stars

lowering ride height as low as KW's would allow and you end up with a loose spring when its not under weight (due to stock top hats being larger... I think haha), and they do not sit exceptionally well on the spring perch, but they will do, not a huge amount of suspension noise trasfer

Cisco camber plates on 2002 WRX 5 years ago
5out of 5stars

I got these because I was running 245/40's on 17x9 et45 wheels with Feal 441 coilovers and needed extra clearance. These camber plates look great, feel very solid and well built. I set them all the way negative to give extra clearance between my coilovers and wheels. I've run them for a couple months now with zero issues. No slipping or weird noises. I use the car as a daily driver and my autocross car. The nut supplied to hold the camber plate to the coilover does not fit the Feal damper shaft. Instead, use the nut that holds the stock Feal pillowball mount to the coilover. It's the same outer diameter as the Cusco nut but has the correct thread pitch as the coilover shaft. It works perfectly! They come with Japanese instructions, but you can figure it out by the pictures if you can't by looking at the plates. are very simple and easy to install

      A:  We do not have a confirmed fitment for Apexi coilovers. With the proper adapter it may be possible.
