C5/C6 Front Brake Conversion Kit for the 1978-1988 GM G-Body
P/N 304647
Priced at $469.99/kit

UMI’s 304647 hub, bearing and bracket kit adapts C5 or C6 brakes to your G-body Pro-Tour machine. The 3046 laser cut bracket bolts to the spindle and properly locates the C5/C6 abutment bracket and caliper. The Made In USA aluminum face mount hub along with premium bearings and seals completes the installation. The hub features 5 x 4-1/2 and 5 x 4-3/4 bolt patterns and is intended to face mount the C5 or C6 brake rotor in exact factory location (front track width is unaffected). The kit includes premium bearing cups and cones along with the correct rawhide seal for great performance and reliability. The 304647 is the choice for UMI’s Green Machine and has been thoroughly tested to withstand road race and auto-x competition. 100% manufactured in USA as well as tested and raced out of Philipsburg, PA – USA.

What's the biggest rotor can you use with this kit?

 

[UMI Performance]

This is designed to be used with the C5 or C6 rotor. The C5 rotor is 12.8 and I think the C6 is 13.4. C6 would then need at least 18" wheels.
