ok, so I can only assume this is whats happening. going lets say 75+ on a sweeping ramp I can feel the car literally dropping the gas pedal and slowing down as if someone applied the brakes. tires are 315 rears and 275 front. to also put this in perspective, the car is NOT trying to actually save me, I am not going that fast for these ramps. I could easily go much faster. its annoying! any thoughts?

No tire slip when accelerating?

That doesn't seem to make sense to me. Unless your tires are starting to lose grip there shouldn't be any reason for the nannies to kick in. And like you said the tires are sticking like glue. May need to take it in and have the run a diagnostic check.

I have a ramp, with the car in mode 3, and put it to the floor, in an attempt to get the nannies to kick in, but failed on every attempt (at least a dozen attempts) got up to over 100mph in the turn with no tire chirps, but I chickened out each time and let off. The damn thing was flying and still sticking like glue! Scared the crap out of me each time. Took like ten minutes to get my hart rate back to normal.

Which ramp?

caper · 08-02-2014, 03:03 PM

215s to the 210 w...I am not accelerating so I am not breaking traction. basically I just carry the same speed through the turn. its very noticeable. its an uphill ramp. other times I will rail around other ramps at a much more intense speed and nothing kicks in. even on this one its intermittent, but it happens.

Just because you're not accelerating doesn't mean you're not losing traction. Could be crud on the road too. The simple test/fix is to turn everything off and see what happens. When I added hp and wide sticky tires the system got really confused but I turn it all off usually anyways so its a non-issue.

The combination of 315 rears with front and rear bars of almost the same diameter creates understeer. Set you rear sway bar to full hard and and your front bar to full soft. Increase the front negative camber. Decrease the rear negative camber. Run your front tire a few pounds lower than your rears. This will bring some balance you your setup. The stability control will still kick in, but it will be at higher speeds.
