the markets been swamped the last few years with so many new variables of the materials the products are made of and the quality of the same.
i know ya can save tons of bucks and get cheap inexpensive rotors and pads... might be good for the way you drive yer car... on the other hand, if yer a tad harsher on yer ride, i'd step up to a higher quality set up...
if yer Real hard on the Ol' HotRod... BUY THE BEST. the highest dollar, highest quality rotors (made with better materials) and the best, top of the line pads. whether ceramic, semi-metallic, carbon fibre... get the best pad the rotor manufacturer offers...
Raybestos, Wagner, Eis, Napa any top of the line company will have multiple grades of product to compete in the market. good ta compete with good
and the cheap/inexpensive to compete with same...
whatever ya do one the front... match the quality in the rear too...
