If you are looking to upgrade the braking on your E46 CSL M3, replacing your calipers for Brembos from a Porsche 996 is a great option, the only problem is getting them to fit! Creations Motorsport has the solution with their high tensile SG strength caliper adapter brackets. Included with high strength stainless steel mounting hardware, these nearly indestructible brackets will give you the ability to upgrade to calipers that offer a much higher clamping force, bringing your car to a screeching halt.
These adapters are designed to let you use the CSL M3 345mm x 28mm rotors - part number: 2282445446 (See ES11532)
For fitment, 5.5mm of material must be machined from the mounting boss of the caliper.
*For some BMW hubs, 3mm may need to be ground off of the outer edge. See pictures above*
Part Numbers for the Porsche Calipers: 996.351.425 & 996.351.426
