12" paddles and smoothies

well as you all know we you want to run a 12" Rockstar Rim with paddles and smoothies the rim hits the brake caliper so you are told you can just grind down the edges of the caliper ... or you can make new caliper mounts like I did ........ lowers the caliper im not sure on pricing yet but im guessing about 50.00 for the kit exchanged for your old ones we use the stock pins .......
