Are you looking for a kit that fits under stock GN wheels?
Is your car lowered?

Summit Racing lists many kits to choose from.
The SSBC kits list a 15 inch wheel, but ours (GN wheels) are reverse mount and have a smaller I.D. than most.
I had an SSBC kit years ago, but the calipers are close to the frame and hit with a lot of buddies in the back seat. This is the reason for the “for use with stock height” warning.
The calipers (‘90’s T-bird super coupe) cleared the GN wheels by an 1/8”.
The rotors for this kit are from the front of an ‘86 vette modified to fit over the stock axles. They’re turned down from 11.5” to 11.1” (to fit stock wheels) and the backside of the hat is turned to a larger I.D. and are only available from SSBC.
Just some info that may help.
I have a cheap universal kit from speedway motors that use off the shelf 11.63” rotors which work with strange C-clip eliminators, but I had to make new brackets to rotate the calipers down away from the frame and require larger wheels. The axle flanges need to be turned down to fit. Most kits like this use ‘78- ‘82 Cadillac calipers which use D154 brake pads, the same as stock front pads (reuse the retaining clips).
There are YouTube videos of the in-line tube kit which is similar to the Right Stuff detailing kit.
That’s all I know.

thanks, that's a nice set up i will like to do something like that to mine. so if i would get something from summit i will still need to modify some of the items or it will be a plug in play.
thanks

I believe the Right Stuff Detailing kit is plug n’ play. It seems there are options for drilled and slotted rotors too.
You will have to shorten the steel lines near the calipers for the flex hoses to connect.
You most likely will have to weld tabs to the axle to hold the ends of the steel line where they connect to the new flex hoses near the calipers.
You could make a spacer and hold the steel line with a hose clamp or something.
Looking at the photos, there are some tabs included as well as brake cables. Mine didn’t come with cables either.

These are the instructions to get familiar with the setup.
It would be a good idea to replace the disc/ drum proportioning valve with a disc/ disc as well.
I can’t find a listing at the moment.
It seems lately guys are having trouble with the brass ones leaking.
Wilwood has an aluminum one.
