Default Need rear brake pad recommendation

I have a 2013 GS. I have an AP Racing BBK on the front with Ferodo ds1.11 pads and OEM calipers and rotors on the rear. I want to go to a one piece pad in the rear. Car is pretty much stock. Running Toyo R888, 2.5- F 2.0-R, mostly do Willow Springs and Streetsof Willow, occasionally Buttonwillow. I have a race seat with 6pt harness. What do you guys recommend? XP8 or????
This is for road course track use.
Thanks kindly.

You can play around with the brake bias if you're only doing the rear pads. Talk to the pad companies and tell them you want a little more rear brake.

So, I've never glazed the OEM compound and I've never cracked a rear rotor. I do have taper issues which I'm hoping may be mitigated with a one piece pad.

You definitely need to talk to a brake company to find out what pads they recommend..

Also give them the temperatures that you're running. Your pads might not be getting hot enough. You want to see about 1100- degrees on the track. That's a rotor temp. just as you Come off the track.

"The original brake pads that came with your production car operated best in the 100° to 650° range. Race pads operate best in the 600° to 1500° range. Race pads are just getting effective at roughly the same point where the OEM pads are becoming useless."

If you are going to stick with the endurance Ferodo DS1.11, then I will recommend the G-Loc R14, which is also their endurance pad.

As Richard stated, give G-Loc a call directly and describe what you are wanting to do. The pad companies are the experts.

The Ferodo DS1.11 operating temps are lower than what you've stated. I've had two track days on them and I'm happy with their performance. I'm looking for a match for the rear. I know Ferodo makes a DS1.11 for the rear but they're the padlets and I'm looking for a single pad.

Thanks Adam for the reply. Can you possibly explain why the XP10 vs the XP8?

Yes, because of the tires you are using. The 10 will hold more heat and work better in it's heat range than the 8 will.
