Smike, are you running those Axxis ULTs on all four corners? If so, what is your impression of them now? I've got my eye on a set and you're right, they are waaay inexpensive. I'm interested on how they're holding up.

If you are not prepared for: dust, noise, ect... don't bother. ALSO a good brake stab every morning helps to get a little heat in them, and after the car gets washed. Not for the faint of heart. BUT if you do any out of the ordinary high speed runs, they are great. I won't go back to normal pads. I drive aggressive, hit apexes when I can ect... I hope that helps.

Regardless, last nights events has me looking for a more capable street pad. I love how they are low dust and low noise, but the fact that they cannot take 2 runs just kills me.... especially if I ever have to brake hard.
You recommend anything SWOLN?

Have you figured out a good solution for cleaning of the PFC 97 brake dust? I am finding that the dust really gets crusty if you let it sit even for a single night after an autox and then the dust ends up rusting on the wheels!

I do try not to get the dust wet, and that does help. However, I was hoping someone might have found a paint-safe wheel cleaner that was strong enough to remove the crusted brake dust and resulting rust.

I couldn't get all of the dust off. Some of it was really caked on. But it got a good chunk of it off.

PAM non-stick cooking spray before auto-x. If its for your DD then a light acid solution. Interestingly enough my front rotors, PFC's, don't have nearly the amount of sticky dust that my Centric rear rotors do. The rust is the rotors not the pads.

That said - when I was using stock brake pads on the Centric rotors I did not have the rust problem...perhaps the PFC97s are just aggressive enough to shave metal off the rotors.

I've used PF pads on stock, centric, and racing brake rotors. It's the dust from the pad material that cements when it's densely packed and gets wet. Which is why the dust cements on the lip of the wheel and not on the spokes or around the fender wells.

Ran the PFC 01/97 combination last weekend at Shenandoah with Star Specs and was shocked by how much braking power I had. I intended to be on R Compounds but had an issue with getting a wheel in the wrong offset.
Anyway, they're definitely too much pad for street tires as I could trip the ABS very easily. Also, I noticed that if I caught up to a train and wasn't able to brake hard, they lost temperature quickly which didn't seem to hinder stopping power but they would becoming IMMENSELY loud on track.
