These are the brakes found on the new Porsche 911 (996) Turbo.  Mov'it adapts them to fit a variety of cars, including F-Bodies.

Yes, the stock brakes really are this small!

After "getting by" at the track with my stock sized brakes for quite a few events (using brake ducts and PF 90 racing pads), as my speed increased the brakes became woefully inadequate.  My first event of this year I put them into complete meltdown which contributed to a crash.  Besides the crash damage, the heat from the brakes melted the centercaps right off my wheels, ruined my hubs/wheel bearings and melted my tie rod ends.

Enough was enough.  I wanted a real set of brakes!  After much research, this is the kit I chose.  I believe it to be the best in its price range.  It's not cheap, but compared with how much money many spend on the engines in their cars, they aren't that expensive in the big picture.  Not having a few extra horsepower never killed anybody.  Not having enough brakes has.

 

 

The brakes consist of 330 mm by 34 mm (13" by 1.34") Porsche rotors redrilled for the F-Body bolt pattern with 4-Piston (36/44 mm) Porsche Monoblock calipers (manufactured by Brembo to Porsche's specifications).

Their shear size provides a much larger heat sink to keep them at a lower temperature when a large amount of heat is put into them quickly (like braking and the end of the front straight).

 

 

Here you can see the intricate cooling fin design of the rotors.  Notice how the cast-in holes (all other manufacturers of "cross drilled" rotors drill the holes after casting) cut into the main cooling vanes.  This virtually eliminates hole to hole cracking  other cross drilled rotors are famous (or infamous?) for.  This also increases the surface area of the vanes by a large amount.

 

Toward the outer edge of the rotors, a second set of cooling vanes (or "half vanes") is added.  This increases the rotor's pumping efficiency and greatly increases the surface area of the interior of the rotor.

All of this keeps them running cool by making them efficient at transferring heat to the outside air.  That's the key to longevity of brake rotors.

 

 

The "ears" must be cut off the LT1 spindles (obviously) and the caliper mounting bracket bolts to the spindle using the rear two hub bolts.  The bracket is machined from solid steel and is truly a work of art.

Much better!

The rotors have a huge swept area compared with most other 13" rotors and the giant pads (76.5 cm² area each) use every bit of it.

I'm using stock Porsche street pads on the street and at the track.  On the street they don't squeal, they don't dust much and generally are very nice to live with.

On the track, they provide all the stopping power I need, don't fade at all, the pedal stays firm and it looks like the rotors and pads will last a very long time (unlike the stock components).
