Cusco Rear Pillow Ball Upper Mounts Subaru 2002-2007 WRX / 2004-2007 STI

By replacing the upper mounts with Cusco's pillow ball versions, improved steering response and performance is observed. These mounts help control unwanted forces under acceleration and braking. Constructed of 6mm thick aircraft grade aluminum, they are up to handling the demands of competition. 

NOTE: WILL NOT FIT OEM STYLE BIG SPRING SETUP 

These will fit on any coilover that is designed to use a pillowball top hat and not a OEM style top hat. The only thing to be cautious about is to make sure that the thread pitch on the nut that hold the top hat to the shaft is the same as the coilover. These Pillow Ball Mounts come with a M12x1.25 nut for the top hat stud. So please make sure your coilover suspension matches that. Other nut sizes are available thru Cusco.

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).
