    ST41 is a smaller caliper, designed for rear wheels or cars with smaller front wheels.

    I think ST40 may be for cars with 18" and above wheels. Best off reaching out to a Stoptech distributor or even Stoptech themselves.

    I had the ST41 touring kit and they fitted easily under 17s, though they were enkie wheels.

    ST-40 should fit under 17" wheels then, I had 335m discs on my DC5 with 17" wheels on and a larger caliper, but it's best to make sure with the template. You may also need a spacer.

    I had the 330mm kit on my ep3, I had 17inch rotas on it. From memory it will fit standard alloys but only if you have a spacer.

    Amazing bit of kit.
