I've had these bad boys mounted on my 66 2+2 for a year now and I'm very happy I made this purchase. The installation was simple. The car now stops "like" a brand new Mercedes. Only problems I had was that the calipers didn't clear my spokes on my 17x7" Torque Thrust II's. I had to purchase a 1/4" wheel spacers and install longer studs to mount the wheels. Other than that, I'm very happy. I've gotten many people eyeing and complimenting my brakes at the light. Worth the money.
