I have 2 hubs with ears trimmed to proper size mounted to 2 brand new Brembo rotors (266mm), 8 lug bolts and nuts (used), and two v22 calipers (used) with good brake pads on them. Bearings on the hubs have 43,000 miles on them. Everything should bolt up nicely to the XR2 knuckle. I've got $30 in the rotors, $25 in the calipers and pads, $27 in the hubs. I'll sell the components for what I have in them ($82) plus shipping.
Don't purchase this stuff unless you have an XR2 or the proper upsized knuckle.
