You wouldn't be the first, many people have used them on the Z. My main concern would be the fact that the combined piston area on those calipers is significantly larger than stock. This affects ABS performance as well as throws off brake bias. Larger front piston area is going to increase front brake load. The larger front brakes will likely feel stronger but braking distance will be increased due to the increased front brake bias. Do you want to look cool or stop faster? Most of these adapted kits are not properly engineered and many will likely decrease braking performance. Have you ever over heated the factory brakes to the point of true brake fade or failure? If not, upgraded brakes are no more than a styling upgrade.
