Customers highly recommend our product for its ease of installation and great compatibility with Height's style 2" drop spindles and Willwood 2 piston calipers. The product stands out because of its confirmed quality and practicality. It does not work with CPP drop spindles due to the hole size and spacing which makes our product unique and efficient in comparison. Customers would purchase it again, highlighting its quick functionality and quality material.

I had the issue of buying brake calipers and a drop spindle kit from two different companies. These brackets mounted to the drop spindles and allowed me to weld them to the caliper brackets.

Works great with Height's style 2" drop spindles even with Willwood 2 piston calipers, but does not work with CPP drop spindles due to the mounting hole spacing and hole size!

Is this for 69-72 d52 calipers? Will it work with 61-68 full size Chevy hubs and a 79-81 Firebird rear rotor?
