I did use the rotor and hub from a 250R....86-87 are differenet than 88-89's...you need (well this fits for pilot applications) the 86-87's...the hubs have the ring around them connecting the 4 legs with the wheel studs. They have one larger bearing(s..I forget now)...the outer bearing is the same as the pilot one, the inner bearing needs to be replaced....you need to bore the inner bearing boss on the hub out 1mm radial (2mm diameter) to accept the pilots inner bearing. Then they will slip on the pilot spindles.
I LOVE mine
I have no clue as to the similiarities between the 350 and the pilot in this respect, hopefully someone else can help you out with that. Need anymore info...got any more questions, let me know.
I've done a second set for Tmans's pilot, I think I have enough parts to do a third set...just need to dedicate the time :roll:
