Hi all,

I am going down the route of fitting 4 pot calipers to the Golfy cheaply and have decided to use Wilwood Midilites. I have read many times people running 280mm discs on track have had issues of the discs warping, not something I personally have experienced but I have only used std calipers and yellow stuff pads (nothing to metallic).

Anyway, running 4 pots will hopefully generate more breaking power and heat and potentially increase the risk of warping discs on track, to combat this I have decided to run 282mm 25mm thick 4 x 100 discs from an MG, they were cheap at £54 delivered for the pair but required the centres taking out from 64mm to the VW 65mm.

To do this I set them on the lathe with the three jaw chuck, but experienced to much runout. So I decided to bolt them to the face plate. To do this I had to make an adapter because of the hole spacing. I had some billet sitting around.

I cut the billet on the bandsaw then drilled the holes to mount it to the face plate and then milled out relief for the bolt heads.

 

Squared on the lathe.





Disc fitted and setup so runout was less than 1 thou. Then I took the centre out to 65mm.



I now need to measure up on the std upright and machine up some calliper brackets, the discs run a slightly larger offset than std and I hope this means the callipers will sit inboard enough to clear the wheels.
