The point of this thread is to keep you guys from paying $2,000-$3,000 for a front big brake kit, due to this setups very low cost and very high performance. Less than a year ago these fully loaded calipers (comes with clips and brake pads) were selling for about $150 each and the rotors were about $90 each. So the total cost of this setup was under $700 and offers incredible performance for the price. Plus there is a certain bling appeal to such large rotors and 4 piston calipers.
Unfortunetly, GM is always changing the part numbers and prices. For current part numbers and prices call your local dealership and use the VIN numbers I provided in post #3. The last prices I heard were about $190 per loaded caliper and $100 per rotor. As of right now, I'm not sure if the dealer is even offering the fully loaded calipers. I'm going to update this thread as I get more info.
ROTORS
The rotor in question is the big 14" diameter behemoth from the Corvette C6 Z06.
Below is the
OEM unit and should cost under $100 ea. It has proven itself on the race track as well as on the street.
Another option is an aftermarket rotor from the Australian company
DBA. They have plain rotors, left hand or right hand slots only or a unidirectional slot design with cross drilling. All 3 looks are available in their Street series as well as their 4000 series.
These part numbers and prices are from LPI Racing.
Street Series
Plain P/N: DBA 2992 $124
Slotted Left P/N: DBA 2992SL $124
Slotted Right P/N: DBA 2992SR $124
Drilled/Slotted P/N: DBA 2992X $136
4000 Series
Slotted Left P/N: DBA 42992SL $182
Slotted Right P/N: DBA 42992SR $182
Drilled/Slotted P/N: DBA 42992XS $200
Here's a cool video showing how the cooling vane shape works. This next one shows the advantages of the 4000 series for track use.
R1 Concepts also has a replacement 14" vette rotor for $355 a pair. They are pretty cool looking.
The stock LS1 rotor is about 12". As you can see below, this is a big jump up in size.
Here is some rim to rotor size info.
CALIPERS
The caliper is the 4 piston Brembo made unit that is taken from the 04-07 Cadillac CTS-V. This is the same basic Brembo caliper that is fitted to many high performance cars such as the Viper, Lotus Esprit, etc... and has a proven track record.

UPDATE: Wesmanw02 has installed this setup and taken many pictures. He needed to space his rims out about 15mm (0.6") which is less than the 3/4" (0.75") needed for an adapter, so he chose a spacer and longer wheel studs.

Below are some shots of the washers and brake lines that everyone seems to ask me about.
