I bought these for a Sierra I had, but sold the car before they got fitted. They were supplied by a chap on the Ford Sierra Owners Club forum, and have never been fitted. They're for cars with disk rear brakes. I don't know if they'll fit Cosworth models, perhaps someone could confirm this? But they should fit all non-Cosworth cars with rear disks.

Ideal for lowered cars to prevent too much negative camber on the rear. Brand new, never fitted, and seem to have a good repuation amongst FSOC members. £25 posted to you
