Thank you very much for replying Mr. Reilly. A rare occurrence but I can understand how busy you are and agree that such endeavors can be unproductive.
One comment is in regard to the weight difference of the Wilwood Pro. I believe the (significant) weight difference is in relation to the whole spindle/caliper/rotor assembly with the difference actually being in the brake parts; not the spindle itself. I'm sure you already know this but I just wanted to clarify it for the forum readers.
