reducing wheel lock up with cheap pads at autox??

MIKE_STR

How the hell are GCU XP20's going to help me? They are supposed to have loads of initial bite... Why would I want that if my brakes are locking up?

That was a joke, I was talking about overkill and how I'd buy your pads later on.

What the f are you talking about? Do you even know what ice mode is? Good luck trying to continue to threshold braking without engaging it at random times.

And mike, no I didn't bother trying as I gave up on autox. I just know ice mode is and will continue to be a problem. The common theory of rear brakes locking up, I just don't buy it as the only reason as I am getting it despite playing around with my pad combos.

Yeah guys, I get ice mode when I leave crap / street pads on when I track and they can't distribute the heat. They f*ing glaze. Especially the back ones, then the whole system freaks out. Problem with underpadding is that you will get fluid boil and pad fade and it will not be predictable whatsoever. I really think a driver mod is the solution, and I mean that unoffensively.

Who says it was for track? The way the 370 is, you will chunk the pads within two hot laps. I am just tossing a possible workaround for autox on ice mode, not sure what the driver has to do with it when the abs flips out. Chances are that most non experience drivers aren't even getting it anyway as they are not hitting the brakes hard enough.

Based on cossie's lap time @ Laguna Seca, I think he has decent driving skills

Wow a second faster than Martin in a stock Z with plugged intakes, first time there.

I read the part where you said it wasn't for tracking. It's in the title as well as your easy-to-answer question. The car may not know if you're faking it but we do. Driver Stomping on the brakes ANYWHERE is a key contributor to ice mode. If you don't get that, pull the fuse.

MIKE_STR

You aren't contributing. You know nothing. The ice mode isn't instantaneous upon "stomping"... It activates mid braking sometimes.

Maybe the car can't be used effectively for autocross. If I had 10 seconds to plan every braking point like a real racer like you I probably wouldn't have this problem...

I am not seeing how your theory holds up given I stomp on the brakes hard at every track and parking lot that I have been to. East coast, west coast, track, autox, concrete, asphalt, summer, winter, slicks, snows, summer tires. I am sure the events I attended in the Z is no less than you. Given you are so fast, perhaps you can figure out why ice mode is still there.

I don't have plugged intakes, does the stock one count? My car is so modded that I don't have a working 2nd gear on track anymore.

You're not listening, comprehending, or learning- it's not my problem, and not your thread.

threeseventy

Sorry maybe I wasn't clear. MARTIN had the plugged intakes, first time out, stock Z (back in the day) with your experience you should be in the LOW 40's if not 30's with all your mods, if done correctly. Is that an old time?

Only time we get ice mode down here in SoCal is when we knowingly run old fluid, beat pads, and go in too hot. You're likely overheating whatever pads you're using or the "surface" you're on has inherent traction challenges- what is the ambient temp? Do you have vented brakes? How thick are the pads? If these are sanctioned events I understand why you can't just disable the ABS but otherwise.. crappy pads are, in fact, an absurd solution as you stated.

What pads, rotors, tires and size are u running, disconnected the yaw sensor out?

Lol and yes my time was first time ever at Mrls and sadly I didn't have time to do any setup prior to just getting on track blind.

Ice mode has nothing to do with glazing/fading the pads...it has to do with brake activation and what the yaw sensor sees. Turn the wheel and threshold brake...you are probably going to get the abs to freak out regardless of pad/tire selection. You can diminish its impact with pad, brake and tire selection, but not likely rid yourself of it TOTALLY without going to a motorsports caliber ABS set-up, which cost $texas. Having said that, I have not had an ice mode issue on my car in years. For whatever reason, the front stoptech 332 and rear brembo set-up seems to work well with the factory equipment. I run bigger, stickier tires than anyone on this forum FWIW and use junk/crap stoptech street pads.

If we're talking about Ice mode;
I run Hawk HP plus with slotter rotors on all 4 corners, with stainless lines, and the only time I've had ice mode issues is when I'm running my Kumho V710's, and only happens to me on hard braking. It doesn't happen when I'm on street tires.

A random guy came up that saw I was suffering from ice mode at my last autoX, told me to double tap the breaks, as to let them out completely and then go back in hard, and it seems to have solved the issue on my last two runs, which were my quickest times of the day. (Thanks again random guy)
