If you want your car to have maximum stopping power, then this is the conversion to provide it. 4-pot alloy calipers and vented discs allow you to rein in your MGB more consistently and more safely than ever before. 4-pot calipers allow you to apply more pressure to a larger pad than is standard and having vented discs gives a greater surface area over which to dissipate the heat produced from applying pressure to the brake pad. We offer a variety of pad combinations from road to full race specification, depending on your requirements.
