Sams Shed

I spent some time in Solid Works designing a sheath to go over the existing Spindles as they are tapered and only have a maximum diameter of 20.5mm and the RX7 FD brakes require 33mm. Standard 323 Spindle: Solid Works Drawings for Spindle sheath Next will be to design some brackets to go mount the new brake calipers to the existing location. The backspace between the strut and the new disc brakes should only be around 6mm more than std due to the thickness of the disc centre where it fits over the new Hub.

After getting the std brakes off the car it is obvious that the std spindle is going to be way to small being 17.4mm at the front and 25mm at the rear with two flat sections and a taper in between. The std FD HUB is a uniform 32.5mm so a sleeve will need to be made up to fit over the 323 spindle. To this end I've been working in Solid Works to CAD up a design for the sleeve. I will use an M33 3mm thread on the end to secure it and will be TIG welded to the standard Spindle.
