This page contains brackets needed to mount various brake setups to modified 82-92 F-Body front spindles.
1998-2002 Camaro \ Firebird LS1 Brakes
2004-2007 Cadillac CTS-V OR 2010+ Fifth Generation Camaro Brembo
This bracket will allow a few combinations of calipers and routers to be mounted. This works with a 1998-2002 Camaro / Firebird caliper with matching LS1 12-inch rotor. Also the bracket works with 2004-2007 Cadillac CTS-V or 2010+ Camaro 4 piston Brembo brake calipers using a C6 Corvette Z06 14-inch rotor. The LS1 and CTS-V calipers use 12mm mounting bolts and the Camaro calipers use 14mm mounting bolts so there are two hole sizes in the bracket file autocad to accommodate either caliper. There are two seperate DXF files, one for each hole size.
For LS1 brake setups the bracket should be machined out of 5/16 inch thick steel and you can shim out the caliper with hardened steel washers as needed. In some cases you can machine the bracket out of 3/8 steel but it all comes down to the tolerances of the rotor, caliper mounting bracket, caliper carrier, spindle, and hub you are using. To be safe a 5/16 bracket will always work with washer shimming.
If you are doing a CTS-V brake setup the bracket should be machined out of 1/4 inch thick steel when using a standard hub or a 3/8 bracket with the 1LE (HD) hub and add another 3/8 spacer to bring the bracket far enough out to shim the caliper on the center of the rotor. I am not very comfortable with a 1/4 bracket thickness but have seen others use it on other brake swaps. You will need to space the caliper out away from the bracket to center it on the rotor and to clear the lower spindle bolt. Another option is to use a 5/16 bracket and shim the router out slightly with router shims.
When shimming the caliper use hardened steel washers so they do not compress and a feeler gauge to center the caliper on the rotor.

Corvette 1988-1996 C4 HD & Non-HD Setups
The C4 12-inch and 13-inch HD setups use the same bracket. When using a C4-HD (13 inch) brake setup this bracket needs to be 1/2 thick to properly position the caliper mounting bracket. I highly recommend having the bracket cut out of 3/8 inch steel and using two 1/8 inch shim or washers to space the caliper mounting bracket out to reduce sprung weight. Bear uses 5/16 inch thick brackets so it would be safe to use that thickness also with a 3/16 inch shim or washer.

Corvette C5 & C6 Brakes
This bracket will work for all C5 brake, C6 Std JL9 (12.8″ rotor), and C6 J55 Z51 (13.19″ rotor) setups. This bracket also fits RaceCrafts 2″ drop spindles. This bracket will not work with C6 Z06 or ZR1 brakes. The bracket should be 1/2″ thick.

1998-2002 Camaro / Firebird F-Body "LS1" Brakes (OLD DESIGN)
It is highly recommended to use the new CTS-V \ LS1 bracket which works with both CTS-V and LS1 calipers. The new design (see top of page) fixes a slight offset of the caliper mounting holes, if you use this bracket there can be some clearance issues with the caliper bore hitting the bracket and the caliper not sitting center on the rotor.
(Holes labeled "C" are where the caliper mounts, holes labeled "S" are where the bracket mounts to the spindle)
The bracket should be cut out of 3/8 steel.

Original 12-inch Baer Brakes Bracket
This bracket is designed to be used with a Baer brake caliper carrier (abutment bracket) . From my research it seems Bear brakes used a corvette C4 13″ caliper carrier or similar. It may be possible to use the 13″ C4 caliper with 12 inch rotors but has not been tested.

Viewing and Printing Files:
You can download a free autocad .dwg fileviewer here; Autodesk Design Review and AutoDesk TrueView. AutoDesk design review software is very useful if you are making the brackets by hand as the software lets you setup and scale your printer so the brackets will print out 1:1. If you are using the PDF to print a properly scaled bracket you will need to scale the bracket in the print options until the scale check lines measure exactly 6 inches.
