NA Miata and G-Loc brake compound

We just recently put a set on our miata. Running r18's up front and r12's out back. We only have a track day on them currently. Ambient was 28*, so we never got them into their operating temp. Didn't have a ton of grab, but I assume at Harris Hill, we'll see them come into their own.

G-lock compounds are the same as Carbotech. We run the latter religiously. XP10 on the front, XP8 on the rear of our NB Miata. They do need some heat to work. Some of our drivers are as hard on brakes as you can be in a Miata and they last almost exactly 24 hours without any ducting.

 

Higher numbered compounds are designed for higher heat (weight) applications. Each step will require a little more minimum heat, bite a little harder, and last a little longer on a given vehicle.

 

Make sure you bed them properly.

Thanks for the info. I think we'll stick with the R8 compound for now. As we're newer drivers we're definitely not that hard on the brakes yet and they worked great at Sebring.

 

As far as bedding them properly. I'm all ears for tips on that one. We can't drive the car on the street, well legally, so besides dragging them as I cruise up and down my street what are some other ideas?

You can pay carbotech to do pre-bed for you. They cook them in an oven.

 

Otherwise:

"1. Perform several moderate (medium) near stops (to a very slow rolling speed) to thoroughly warm up the pads and rotors. This should take 1-2 laps. This allows a thin layer of the pad material to be transferred into the micro-grooves of the rotor.
 2. After the pads/rotors are warm, perform a series of hard near stops (to a slow rolling speed) until some brake fade is felt. This process should take about 2-4 laps (depending on the track). Once this occurs, then stay off the brakes (as much as possible) and bring your car into the pits/paddock to completely cool. Do not lock the tires during this operation.
Allow brake pads and/or rotors cool down to ambient temperatures; no less than 30 minutes. The total bedding procedure should not take more than 5-6 laps or about 10-15 minutes."
