Changed my brakes after 2 track days did them in.

    So after ten 20-minute sessions on the Main Circuit at Summit Point, WV, my brakes were pulsing pretty badly. I know they had been toasted a bit.

    The ones on the right were a little worse than the left. This makes sense when you figure the torque vectoring function is going to clamp the inside wheel on acceleration. (Summit Point Main goes clockwise)

    I just received 2 rotors from Amazon http://www.amazon.com/gp/product/B00J5DTH0W/ref=oh_details_o00_s00_i00?ie=UTF8&psc=1

    and a set of brake pads: http://www.amazon.com/gp/product/B00J5BJFS8/ref=oh_details_o00_s00_i01?ie=UTF8&psc=1

    And they were the real FOMOCO deal, arriving in 2 days.

    Here are a few pics of the old ones... they had some crazing on the surface of the rotors, and the pads were pretty much gone. I'm glad I changed them before this week's autocross.

    I am disappointed in the lifespan, though. Yeah, I drove the living s out of them. But I did my best to let them cool down while moving, and the rotors warped anyway. Does anyone think these can be turned/saved for spares?

    The bottom line is, I can't wait until Hawk or some other vendor starts making pads for the FiST. Something less likely to become so roasty. <-- that's a technical term.

    How were the brakes performing though on the track until they got too hot though? Was it gradual or a wall?

    They never failed me altogether. I did overcook a turn and had to take it outside the line, but the brakes were mostly there. Fade was minor, and gradual at that.

    Not complaining about performance here... Just wishing the rotors hadn't been warped in the process!

    Does Centric make a set yet? They bought out Powerslot a while ago, but they have some good rotors for the money.

    I have to keep the rotors oem(-like) for g-street class in autocross, but I'd be interested in aftermarket pads. Hawk is developing for the FiST and they should be out in a matter of weeks, according to the inside sales rep.

    Arent the stock pads pretty aggressive? Mine make nice grinding noises until I get some heat in them coming down my hill in the AM.

    No surprise they ate through a rotor and the pads turned to dust under those conditions.

    Buy some Portefield R4 pads! :)

    See the related threads in "Road Race - Porterfield Pads".

    That's what I did.

    But seeing this thread makes me think I should get a spare set of rotors because if the stock pads did this, the R4's are gonna cook them even better.

    It's hard to say. My rotors look fine, and I ate the pads over a few track days. I'm already easier on the brakes, however. I can't say anything about the OP, but I know that I was over-driving the car; that includes being too hard on the brakes. It's already evident my brakes will last longer. I pitted with my old pads smoking a couple times on my first day at Big Willow. On my 2nd day, I was seconds faster per lap, but never had "pads on fire" again.

    I'm also on the same set of rotors, but will order a spare set soon. They're not even close to being done. Yes, the R4 pads are much harder on them, but even they last longer than is being described here. I'd advise caution on reading too much on this single data point. I suspect something else might be at play (remember some people have warpage issues on normal street driving!).

    No question the pads will outlast stock pads. I'm glad that Porterfield had pads before my track season started because I had figured on going thru a set of OE pads every weekend.

    The rotors are cheap enough that having a spare set is probably worth it.

    Yes, I agree with that. I just checked out the Amazon link and noticed there were 4 rotors left -- so I bought two of them. I'm quite an Amazon junky...

    Amazon Prime and setting up one-click payment was the worst thing that ever happened to my credit card :)
