Underground Motorsports sells the bracket and hardware for $299.99

For this price you get the brackets and high grade bolts ( two Hex head, Grade 10.9, M12 x 1.25 and two Allen head, Grade 12.9, M12 x 1.25).
I purchased the whole package from Underground Motorsports. They don't tell you that you have to get the rotors machined once you get them, which cost me another $100. If I was to do it over again I would have just purchased the kit from McKinney. I believe they sell the kit with machined rotors.
Figure the price of the brackets, (4) high grade bolts, Brembo Supra TT rotors, the cost of having the rotors machine, and your time ordering parts and having parts machined and the price will probably be close to $500, if not over.
With Hawk HPS pads the brakes are great.
