Overall Assessment

Customers are pleased with the product, noting its ultralight design for rapid acceleration. The 1" width is also appreciated as it fits perfectly with metric calipers, eliminating the need for piston spacers. The use of Spec 37 alloy steel is highlighted as superior to cast iron, preventing breakages or cracks. Its effectiveness is noted particularly on the rear of dirt street stock. The product stands out for its combination of quality, practicality, and reassurance in terms of safety.

1" width works perfectly with metric calipers, no piston spacer needed. Spec 37 alloy steel is better than cast iron, no more broken rotors or cracked tabs. Used on rear of dirt street stock.
