Corsa C Pillow Ball Top Mounts
These Top Mounts replace the large rubber mounting that is on top of your front struts. Instead of being rubber, they are solid aluminium bearing housings that encase a high precision, maintenance free, spherical bearing.
Working in the very limited space of the Corsa strut towers, they are designed to push up inside the strut tower, like the originals, and then clamp in place via a locking ring. The locking ring also features locking screws to physically prevent it from unwinding.
Early on in our quest perfecting the Astra G, we noticed problems with the standard top mounts, as they were sat about 10mm proud in the engine bay. No way were the upper mounts staying in one place! Using the same mounts as the Astra, the Corsa C suffers this problem and can utilise the same solution.
We set about designing and made some prototypes, fitting them to our test car. With a few tweeks we had some nice pillow ball type units. We are now onto the 3rd revision, featuring larger bearings for added strength and longevity.
This, along with our spherical front wishbones, allows the wheel to retain it's set geometry whilst enduring any loads, such as cornering, braking, or during acceleration. During cornering it stops the front wheel "flopping" over into positive camber and reducing its contact area with the road. You can run less static front camber with these fitted than you had to with the originals to keep the tyre temperatures uniform, due to the lack of movement.
We have developed them to fit the standard damper / strut top. Any aftermarket dampers that use the original rubber strut top and bearing assembly should work with these, we have had them fitted to Gaz / Bilstein coilovers for example.
If you find that they do not fit your specific set up, we would love to help you make them do so. They are fairly universal, so usually it would just mean some different spacers. Getting them to fit will allow us to expand our list of known fitments, so we don't mind at all. We will fully refund you if we cannot make them fit any damper that uses the original top mount, provided you send them back undamaged.
Designed for competition use, professional installation recommended.
