Oops, sorry, clicked "none" before seeing this...

Unless it's pouring rain, I shut it off. I was going through way to many rear brake pads...Once you get to know what makes the car slide it's very controllable...

I use comp..
The better you drive,the less it kicks in

Same here. Only time it really kicks in alot are when the tires are cold, or the track conditions are very poor.

Curious to see if it works with my new tires which are 25.5 diameter all around.

This poll is a bit confusing since option 1 and 3 are the same.

Competition Mode IS Active Handling ON, Traction Control OFF.
The default is Active Handling ON, Traction Control ON.

Active Handling is the feature that brakes a cross directional tire when the cars direction of motion is different from its direction of steer. (ie Car is going sideways, so straighten it back out to the direction the driver is steering)

Traction Control is the feature that brakes the rear tires when they are both spinning to gain traction. Most people hate that for racing.

ABS is the feature that brakes a specific tire that is slipping in relation to the other tires. (Usually always on)

I voted for competition mode for DE events, but I have found the best lap times with the system turned off. I noticed the ative handiling working when I was not doing anything too ham fisted on the track. I asked the boys at Spring Mountain about this and they thought it might have to do with the tires being at different height when going over curbs. Anyone have any thoughts?

QKSLVR Z · 03-15-2005, 12:05 PM

do all active handling cars have the comp mode? just hold the trac button down?

Duke 1 · 03-15-2005, 12:20 PM

I know the new C6 works differently, but the C5 works like this, to turn off the system push the button, to get to comp mode hold the button down until the comp mode comes up on the dash, very easy.

I turn it all off, although for my first few events I left it in comp mode. With our low-capacity brakes, you'll have to bleed by noon with it on and I like to get through a 2 day DE without having to fiddle with the brakes.

I've heard the argument "if you are smooth, it won't kick in", but I do not buy it. If you do any 4-wheel drifts, it generally kicks in, and at speed, you are going to drift occasionally. If you go over rumble strips, etc., it will turn on. If you trail brake, you can get it to turn on. It is not usually obvious when it kicks in unless you really mess up, but it does kick in and at speed that scorches the old brake fluid.

My dream in life would be to have a brake system you can beat the hell out of and it would last without any deterioration all weekend. But, to turn a phrase, "stopping costs money--how well do you want to stop?"

If I was first staring I would use comp.

However having done this a while it throughs we off sometimes as it screws up when you track out and the car is drifting (high tire slip angle).
Also the brakes cook away quickly it seems.

I'm confused - how does active handling affect how often you bleed your brakes? The only things that affected my bleeding frequency were the DRM brake ducts and switching to Castrol SRF fluid. I typically get 2-3 DE days without bleeding, even then the SRF comes out relatively clear.

Active handling stabilizes the car by applying the brakes in a computer controlled sequence. This adds more heat to the brakes and cooks the fluid/pads that much more quickly.

I understand that, but at most I'd say you'll get additional wear on your rear pads and rotors in particular. I can't see it requiring a bleed mid-weekend solely based on AH. If your line is smooth, it doesn't kick in very often. Unless your trying to trailbrake or slide the car around a hairpin, or something like that.
