I just finished putting together some spare parts I had sitting around in a combination I haven't heard anyone doing before.
I put C3 Corvette 11.75"x1.25" rotors on first gen drum brake hubs just like the JL-8 package used but fit up a set of 98-up F-body LS1 front calipers and baskets.
It looks like it will work but will require machining the drum brake pivot pin boss down a little to allow the adapter bracket and upper mount bolt to clear the rotor.
I haven't had the time to mill the spindle down yet to finalize the fit and shims required but if I can get this to work it will allow you to run the stock 15" rally wheels and get a significant breaking improvement.
It may require flipping the caliper to the front side of the spindle on rear steer applications but could still be used on the back side on front steer applications from the way it looks now. The clearance is tight but once the spindle is cut down and the bracket made it can be moved around a little to see if there is an orientation that would keep the calipers on the back side like stock so the hard lines wouldn't need to be extended or modified.
If anybody has the time and equipment to do the work to try this out feel free to join in on building a prototype bracket and spindle. My car is far from drivable at the moment so any road testing of the package by me would be far in the future. It looks to be a great package for those of us who want to run 15" wheels.
The C3 rotors are only $35 for American made pieces at NAPA so they are not expensive and they came on 65 to 82 Corvettes so they are going to be easy to come up with for many years to come.
