Endless makes some of the best brake systems but in this case, I believe there are better value (better performance is a question mark since I have no experience with any brake kit for now) from AP Racing or other vendors for the price they are charging on this special 86 kit.
Personally, I think the car works fine with a floating 2 piston caliper, uprated pads, brake lines and high temp brake fluid for its 200 odd whp setup.
