reducing wheel lock up with cheap pads at autox??

cossie1600 · 03-28-2014, 09:24 PM

Unless you know more about my car than myself, I seem to recall my car went out with stock everything except pads and R-S3 tires my first time too. Even now I have what, a set of sway bar and coilover? That adds 7 points in NASA scale maybe? I guess that should be enough to make my car as fast as a GTR.

Overheating what. I can hit ice mode on my first outlap with the XP10. My XP8 wouldn't hit it until the later laps. There seems to be no consistence around it, making it so scary.

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.

Serious non troll question here, so is your ice mode issue more prevalent Auto crossing then on road courses? Or is it about the same in ice mode intervention with both genres?

I get them in both. The big driver seems to be the pad compound. The more aggressive they are, the easier it is to get it. I have tried to swap different rear ones, but the problem still seems to lie somewhere around the front pads as that's what made the biggest difference.

The second driver seems to be the pavement. It doesn't matter what road course or autox course I am at, most of the ice mode seems to kick on around the same spot. If I get ice mode in turn 2 as an example, it would seem to come back around the same spot. I think it might have something to do with the bumps in the pavement.

I have also tried to soften how I hit the pedal, but it can still be a hit or miss. At this point, I just brake 25/50m sooner to compensate for it.

I know you've said in in separate posts, but what front to rear pad compounds have you tried, and have you pulled your YAW sensor plug?

What about yaw sensor? I never tried those pads before so can't comment

cossie1600 · 03-30-2014, 03:04 AM

No, never disable the sensor. Car was almost always stock, but i got it with the coilovers anyway.
