hey joe....i'll keep an eye out. i don't know what it is but i usually have great luck finding parts for some reason. btw...are spindles from a 951 S the same as the spindles on the 928S4? or is the only thing they share the rotors and calipers?

928S4 spindles are different, as they use an upper a-arm. Only the calipers were used on the 951S.
By the way, there is a complete 951S suspension, front & rear, on ebay right now. Not cheap.
I just bought some 951S spindles, hubs, and rotors, & calipers. The hubs seem to be interchangable with non S units, (except the non S hubs do not have the ABS "gear") and both use the same bearings. Besides taking an S4 caliper without an adaptor, the difference with the S spindle is it moves the hub out toward the fender about 1/4 inch to ensure clearance between the thicker S rotor and the ball joint. If you use S rotors and calipers on a non S spindle, you may have a problem with the rotor being too close to the ball joint. I don't know if the aftermarket caliper adaptors and rotor hats address that or not. They can't give too much ball joint clearance without interferring with the wheel/caliper clearance.
