What are these brakes?? Any good??? I have found a racing disk brake kit by me for sale and I don't know anything about them.Some help would be great

They along with Wilwood and Hurst Airheart have been making racing brakes for along time. Way before Outlaw Calipers, or Areo Billet kits. I would think they will be as good a quality as any Wilwood kit.

So JFZ was building breaks for many years. The are very similar to lamb brakes but not as light. I have a set on my 82Z in the rear & I love them.

About 6 years ago Sierra Racing Products (in Carson City, NV) purchased them. They still support all of the products but they are now made under the SRP name. Not the same SRP that makes pistons.

IMO I would say that they are better then Wilwood
