I’m just putting this out as a feeler for interest.
Planning on a production run of billet aluminium rear hub carriers based around the C082D4141/2K castings. The design work is now complete and production of the first prototypes is underway. These will be made from 6061-T6 aluminium and calculations indicate they will be approx. 4x stronger than the OEM/aftermarket castings.
The billet alone is in the region of £300 per hub, so the pair post-machining and finishing are going to be significantly more expensive than the cast equivalents.
The billet version will also be a little heavier due to the material density and are designed for superior strengthening required for competition/track/fast road use. With modern tyre technology, poly bushes, upgraded suspension and modified engines additional strength in the rear upright gives greater safety margin. These should be lifetime items.
Final pricing will be based on the production run numbers, but you can assume they will be at least 3x the cost of the cast units. The hubs would be supplied with Oilite bushes and stainless lower pin.
Anyone seriously interesting in a pair please PM me.
