[TPR] GR4 Racing Brakes

[Mike Trusty]

Photo 1 is the front caliper which is the "GN" Grand National unit.  I have
run 15" Gotti wheels with this setup and it should work with 15" Pantera
wheels.  These are 17" wheels.

Photo 2 is the back side of the front caliper showing the required adapter.
The adapter is very easy to make.  You can also see the model number on the
caliper.  Note that they are left and right specific.  The last two letters
in the model number designates that.  Also note the massive clearance with
17" wheels.

Photo 3 is the rear six piston caliper.  They are the Wilwood Billet
Superlite 6 lug mount calipers.  They are also side specific.

Photo 4 is a picture of the front 15" Halibrand wheel on my GT40 that uses
the same GN caliper with 12.19" rotors and they fit in this cast wheel.
Tight but fit with no mods.  

These brakes were designed and used on 3,000 lb Winston Cup cars and are a
lot of brake for a Pantera.

I have driven Gary Halls Burgundy Express race car at Pocono with these
brakes.  He had a booster in the system and I considered them as too
sensitive with the booster.  Very touchy with the booster.  I use a manual
balance bar system and really like the feel.  The list price on the calipers
is about $385 each for the fronts and $374 each for the rears but you can
likely find them cheaper than that.
