I've got Porsche 5x130 pattern on my 1970 bus. Porsche 944 turbo front hubs, vented discs and cailpers & 5x130 pattern earlybay rear drums with 5.5 Gasburners all round. Fuch have been done to death all over the globe and the CSP disc brake kit quite frankly for the money are poor, driven a few buses with it and I wasn't that impressed. Over a grand for Vauxhall Astra brakes, no thanks.
