Vintage 1970's-80s Wilwood Grand National 6-Piston Brake Caliper - Gold Anodized

According to information provided to me from Wilwood (as usual, excellent service from their tech line), these are an early version of the current Grand National caliper:

 

"What you have is a late 70’s, early 80’s Grand National six piston caliper. These calipers have slowly been taken over by the W6A and the new radial mount Grand National [ed. note: Grand National III] caliper. Here is a data sheet from the latest version of the calipers you have:

Unfortunately, we never built any brake kits for street/passenger cars using these calipers. These calipers were used specifically for racing and would have had fabricated brackets make in order to mount them to the cars they ran/run them on."

 

These speed parts were used on (or kept as spares) for the cars Jeff raced from 1977 through 1987 (particularly on the 1982 Camaro below, I'm told): www.racingsportscars.com/driver/photo/Jeff-Loving-USA.html
