Got a track related question? I'll try to answer.

@DocWalt you're definitely overheating the pads; the 71R has more than enough grip to help facilitate that. I think you'll like the BBK.

Rears look overheated too, no?

What do you think caused the pulsing, not letting them cool long enough or just smeared the pads too badly?

Most likely uneven deposits on your rotors that is a casualty of smearing. You can keep using the pads/rotors and the deposits would eventually "wear off" and the pulsing will go away.

Side note: the even overheating of front and rear is a good indicator to me (along with the tire pictures) that you are *NOT* using ABS, and are actually overheating the pads, not abusing them via ABS.

Good to hear I can likely save the stupid rotors that I literally just replaced...

I think I ruined the RBF600... With the stock pads back on the car I can push the pedal as hard as I want and never hit ABS even with cold-ish tires. It was the same after the last track day, I'm not impressed. I'm giving RBF600 another try with the AP kit (I have a few brand new bottles a few months old to get rid of) but if that doesn't work I guess I'll be trying the RT700 or Project Mu fluid.

edit: BTW, posted the track videos in the thread in my signature if you're curious.

Should I try XP12 or Club racers next? I am on AP sprint kit and I almost burned through this front set of XP10 in 2 weekends, probably got 1 day left in them.

I read a lot of good things about club racers so I'm leaning toward that.

Maybe in a month or two I have one more new set of XP10 to use and haven't book any days gotta check my schedule.

Random question also, what cordless impacts are you guys using? I want to get one soon and install ARP studs so I can make my tire changes faster

I'd consider Endless RF650 as well. Good stuff.

Maybe consider the PFC 08/13 combination. It's not super popular in the US yet, but on our stock brakes (with pedal dance) it was a great combination.

As far as electric impacts go, a 1/2" Ingersoll Rand is never a bad call. Not cheap, but you get what you pay for.

Ah, disregard that pad recommendation, then. Not available for that caliper right now.

I raan o8 in the front and dtc60 in the rear and got the rears locking before the front, once things warmed up. I would go 08 all around.

I am currently running the PFC 08's all around, and am liking them quite a bit. I am on my second set.

What are the advantages of going to the 13 in the rear? Once I wear through my current set, I might try the combo and see how that goes.

Lots of people down here are having good experiences with Cobalt Friction XR2s on the AP kit. Their behavior is somewhat similar to the XP12.

I use XP12 on AP Sprint for track and like the balance of stopping power/modulation/pad wear/rotor wear. It's the only compound I've used on track with a twin/sprint bbk and will continue to use. I like to be able to switch between 1521/xp12/ax6 since compounds get along nicely on the same rotor.

Many cordless drivers will work well, I use Makita tools/batteries, i.e. Makita XDT01Z 18V LXT Lithium-Ion Brushless Cordless 3-Speed Impact Driver https://www.amazon.com/dp/B00O2ZTD3E..._VLirxbMDD4WPR

Do you have brake ducting?

Craftsman with the large XCP battery for the track, Ingersol Rand for home.

Same impact driver that I use. Works really well.
