What is your setup?

My personal preference is for the Project Mu 999.

I am on PSS, with stock power. Primarily used at Road Atlanta with obvious hard braking zones, and I really thrash the car...

What pads are you on now?

ABS? Pedal dance?

HP+ currently, it's the first race pad I've put on my personal car.
I always do the pedal dance, but it doesn't turn off abs. I typically stay off abs, but every now and then it'll kick in while I'm trail braking.

Per Hawk's documentation, that's a 800F pad. You're gonna have a bad time; our entry level recommendations for a novice at the track *start* at 800C/1500F for stock calipers. I'm not surprised you're having fade issues.

Lets step you up to a real race compound, not a "hey we claim this does it all but it really doesn't" compound.

Are you comfortable swapping pads for track days with street pads, or are you going to be leaving the race pads on permanently?

Ouch, I can only imagine the pain those Hawks have endured over the past weekend.

I am comfortable swapping pads. Here is my plan so far:

Order the sprint BBK.

Get some high end pads for the BBK.

Get some street pads that fit in the BBK calipers.

Get a spare set of blank rotors for the BBK.

Drive daily on street pads and blanks. Swap to J-hooks and race pads for track.

Swapping rotors means you have to take the caliper off. I recommend you pick up a bottle of locktite red from Home Depot.

Let us know when you want to order!

What would be the recommendation for the same scenario but where one is interested in keeping the pads on the track and off (and not swapping)?

Race pads, but with the help of someone experienced who can help you bed it in properly. Noise can be minimized with proper bedding and compound choice, but fade cannot, so the only choice is to get a higher performance compound that can be bedded to silence.

Hey @CSG Mike wondering if you've ever experienced this - I discovered some "ripples" on my rotors (can feel it when rubbing finger across the surface of rotor). I'm feeling that they're causing some slight vibration when applying moderate brake pressure when brakes are cold. Same issue on both rotors.

Using DS2500 pads.

Radial grooves are normal. If the grooves are not radial, something is wrong.

[1Cor10:23]

@CSG Mike they are certainly radial, i've seen markings before but this is very "wavy" and you can feel smooth rolling "slopes", if you will, going from inside of rotor to outside. Should I make any change to maintenance or use or is this completely normal? Some has suggested perhaps sanding the pads flat?

Totally normal; you'll get larger grooves on the trailing edges of the J-hooks.

Hi Mike, is the sprint kit designed to run with stock rear pads? Do I need to swap out the stock rear pads to match the front? Thanks

You should be using the same pad compound front and rear. We have plenty of options
