i have 24's on my silverado 1500 and it stops ok for the most part but im going to upgrade to some stainless steal brake company's larger drilled and slotted rotors on stock calipers to up the stopin power.....plus the cool look in the wheel well
wow thats alot of boost...are you going to beef up internals....i was gona run like 6-9 on stock internals....i just have cat back flowmaster 40 series on mine now....its too loud for me....and the tune is here http://www.blackbearperformance.com/
