I have two thoughts on your particular build sir...
What flavor of oil are you running? With the high spring rates needed for a solid roller, I'd run Brad Penn. It has all the goodies the epa doesn't allow in regular oil. My engine builder swears by it. I have an extra case of 10w30 I'd let go for half. I changed to 20w50.
Do you currently have a floating caliper out back? You are changing to a fixed caliper and that may very well put you in the knockback class of 2010.
