Hey folks -

4th track day with a '21 SS 1LE (Camber plates, Glock R12/R8 pads, 315-30-18 square RT660), largely running in PTM Race.

Last time out at Sonoma running the chute config. This has a three hard braking zones at Turn 4, 7 and 11. I found that going into 4 and 7 I would occasionally get a high hard pedal when I'd transition from full throttle to hard on teh brakes. The pedal would kick back on me if I pushed harder on it.

I found that if I slowed down the full throttle to brakes transition by what felt like a 1/10th of a second the weird pedal feel would not occur.

So question - Is what I'm experiencing here what's been referred to as ice mode or hard pedal? It sure does feel like it...

For me it feels like a regular pedal, I just don't get an initial bite and the car doesnt slow down right away. Just feels like the ABS is overriding my braking input and not pinching the pads.

Edit* Maybe it feels like a "hard" pedal. I honestly can't remember, id have to feel it again to be able to tell you that with 100% certainty.

Yes, after initial pedal travel, the pedal feels almost solid and it seems no amount of force can make it move. I've had it happen with square tire size and stock brake pads and with DTC-60s. The more aggressive pads made it happen more often.

Yeah, I went back to staggered.

Couple things ... First I have a regular SS, run all nannies off and 315/30/18 square AR1's. I definitely get the hard pedal with too quick of a transition from WOT to full brake. I recently have been trying to just delay the full braking just a little bit, seems to be effective.

Secondly, who were you running with at Sonoma that ran the chute? I've never seen that configuration offered before.
