I am starting to look as well. JBT brakes have a 6 piston caliper for around the $3200 range. 17 inch wheel up to 330, 18 inch wheel to 355 and 19 inch wheel up 380. They are available in red, black, silver and chrome. Here is the link: http://www.jbtmotorsport.com Has anyone heard of or used JBT brakes?
