Gulfcoast all day every day. CF doesn't come through the cabin when it fails.

I would caution the use of them. From what we see they have a narrow window of opportunity. DBA (Disc Brakes Australia) Race Performance brake pads have an optimum working temperature range of 250°C to 750°C (482°F to 1382°F), and are specifically designed for track use where operating...

Your rotors are fine, no need to replace them, don't let anyone turn them. Any new pad will wear into the micro-grooves in the rotor.

Welcome to the performance brake system club. Track cars disguised as street cars make race car noises. Go out and drive it hard for a while before you start throwing parts at it. It may resolve itself, if the radio works that solves a lot of issues with brake noise. After that we do offer a...

11 years and 22K miles, 10 years with G-LOC R10's. These are the rotors the car was delivered with in 2015. R10's are more rotor friendly than the stock pads IMO.

Yes, all of the above. If its mostly a track car you will be fine. Cold racing compounds will smear, make noise and wear if operated below their intended operating temperature. It can take a session to clean up the transfer layer if they have been subject to extended low temperature braking...

R10/R8 is our go to for anyone stepping up from OEM pads on a street car. The internet will tell you to jump to a R16. It usually ends badly in our experience because people don't let their coaches run laps in their cars because they all think they a Dean Martin or Billy Johnson. Every time...

R10 fronts, R8 rear G-LOCs. I put them on our shop car 10 years ago. Great compromise for improved heat capacity while not being ridiculous on the street. I have data from Daytona, 1.45g's from 150mph into turn one with a Stock S550 Performance pack on a 340 TW tire. They work well, can you...

Do not run the R10's at the Glen, Run the 12/10's at the Glen. I run R10's on the street (for the past 10 years) Just sand the rotors with 80 grit paper to remove foreign pad material and the pre-bed pads will transfer to a clean rotor.

What are you running on the rear?

Side to side(axial) or radial movement?

We offer a KIT for that.

Per Torsen, it should make it work better in a road course environment because Torsens work off of friction. Because you are never loading the tires "equally" through a turn it will help feed power to both wheels more evenly before it starts splitting torque. The issue with Torsen's is if a...

For track use we do not run it, for street use you want to. For the same reasons it is used in the Clutch type differentials. Most modern lubes have a version that already has Limited Slip additive in it. Running the additive in the Torsen calms it down. The Torsen can unlock in a harsh manner...

For the deal on them it wouldn't matter but the ported heads have different flow characteristics so companies like GSC offer different valve events to suit the flow curves. OZ tuning has done a lot of tuning development for several cam companies, if you end up putting the comps in.
