From experience with my buddies , stock pump is fine, but would def get a custom tune to account for mods and max performance.
Also, why not put on a smaller pulley while you're at it. :evil: :rock:
Got them also .... But used the Wagner ceramic quiet stops .... No complaints.
Just remember, as with any brake set-up you buy, just be gentle for the first few miles as you have to break them in.
Just FYI ..... If your interested in a trophy ..... They hold you hostage till at least 4pm :cussing::cussing::cussing:.... And the trophy process can be an hour long. :nono:
..... So you are out of there at 5pm ..... And it gets cold there.
