In-Car at Willow Springs + Off-track dirt action...Thanks Ice Mode...

Shamu

So wonder why mine was getting worse and worse and then when I put vacuum reservoir on circuit it stopped all together? Haven't had a single instance of ice mode since making that mod? That's only change I made to car as well. Same tracks, same tires, same pads. No ice. We use similar fix in Porsche world with fairly good success, but again ice mode in Porsche world isn't like ice mode we experience. At least with Porsches ice mode doesn't occur until you truly are at threshold and tires would be locked up and their system recovers more quickly than the system on370z. My experience with ice in 370 z prior to vaccum upgrade has been from initial application with car headed straight and I have had enough room to reapply and still nothing at all. Literally forces me to pitch car sideways to slow myself down.

I'm sure a burned out pump in some cars contributes to malfunctioning abs but I'm not sure that's our issue.

Also it's tough to compare a time trial car that takes limited stints on track to professionally driven endurance race cars on race slicks as well. That's a whole different world of stress on braking systems. Hell even racing systems fry in those environments.

Just wonder if spec 350z guys are running off tracks all the time like few stock abs system 370z track cars are. I know 350z had mild ice brake issue so does GTr but nothing like 370z.
