Big front brakes
The problem with most big brake kits is that you can not use the stock 16" rims.
The bolt pattern and 'backspace' of the rotors are perfect.
The center hole is a bit too big so you must make an adapter ring in a lathe to center the rotor on the hub.
You also have to modify the rotor in a lathe. Remove the inner rotor near the center to clear the caliper bolts on the knuckle.
The outer diameter on the Corvette hub was slightley too big and the rotor got a bit narrower near the hub mounting surface, so I removed some material from the rotor there too.
The removed areas are marked red in this picture and you can also see both modifications on the picture:
A bought Wilwood Forged Superlite for 1.25" wide rotors.
They are available with different piston sizes.
This is a mock up caliper bracket I made.
The real bracket will be made from thicker aluminum.
As you see in the last picture the caliper has to be moved out slightly.
For extra support I will use distances and bolt the bracket to the original caliper mountings too.
