i started my big brake upgrade today. caliper is a 2005 340mm 6 piston and the rotors are 340mm 2 piece lightweight rotors from racing brake. they weigh in at 17 lbs!!!!
so you have to trim the dust shield and thats it!! bolts right on.
thanx to jimmyskullz,lantanatx for all the legwork, the fotos , the ebay auctions that allowed me to run this setup. btw if you stay with the 340mm you can run 17" rims!! the bigger 360mm rotors req. at least an 18" rim. the rotors arent cheap but almost half the cost of the oem rotors for the slk55 and lighter. WINNING! as i finish everything up ill post more pics
