Final test fitting of the 6 piston caliper went perfectly yesterday. The setup bolts on in approximately 15 minutes per side. Interestingly the 12.2" rotor with the 6 pot caliper actually is only 13.25" in diameter. So in theory if you had a wheel with enough offset it would fit inside a 15" diameter rim such as the Rotas. The stock wheel doesn't have that much inside diameter...

The caliper overhang is approx 1" past the rotor hat face.

 

Will the stock civic or integra MC work with a caliper that big? So when will the kit be available?
