If you have the right calipers you'll be able to just get the offset brackets and run the stock calipers. BUt you need the right calipers first off!!!! look at your calipers on the backside of the piston housing it should be finned, if it is you got the later smaller/cheaper calipers. order some V6 four wheel disc cougar caliper brackets. get some 278mm rotors and your set. I'd reccomend gicing the Stazi rotors/pads a try. I haven't hear anything bad about them...kinda wish I bought them instead of the KVR's.
