Easily install 11" rotors and 1978-88 GM Metric calipers to your 1937-48 Ford passenger car style spindles with no machine work needed. This disc brake kit is great for street rods based on 1932-1948 Fords. For lightweight cars like T-buckets or early roadsters, we recommend the Wilwood kits. This front disc brake conversion kit works well with bolt-on steering arms. The 11" diameter rotors have the GM wheel bolt pattern of 5 x 4-3/4". Calipers have 7/16"-20 inlets.
