I got my car aligned and corner balanced yesterday. I have the Hardbar camber kit installed and the before settings are with the HB camber kit and *no* washers on top control arm. The after settings is what pfadt recommends for stock control arms and R comp tires.





Yesterday I did a half-day trackday with LG Clubsport coilovers and worn sport cups - I have unplugged the steering sensor to disable AH and ran with TC off on my 2013 Z06 .. The DIC threw all sorts of errors and set my top speed limit to 158mph .. but AH never came on and the car ran perfect!! I should note that I only did a few sessions and didn't really push the car hard..

Ttrue weight of my Z06 with half tank gas is - 3180lb. Not bad!

Did you attempt to go over 158 or is there info somewhere that states the car is limited at 158 if you disable AH/TC????? Just curious as I have this disabled on my cars. My C5 definitely sees speeds over 158 with no limiting.......... my C6 that is about the upper limit in good air at VIR so it really isn't an issue and I likely would never notice any limiting.........unless I decide to step the car up.

Just curious.

Am I missing something here? Why did you just not turn everything off via the button??
Also, was that weight with You in the car? If not...then your Z is heavy. I have come in under 3145 with similar mods (car only).

Bro... the newer Z's added weight every year. the 06 was the lightest of the bunch which is why I bought my replacement Z of the same year... Secondly the wonderful T/C button doesn't turn it all off..! and can seriously screw you up and have a very bad outcome. I unplug mine as well and it still leaves the ABS functioning too. but my 09 would do 162 on the straight at High Plains.

Thanks man...I didn't know that. I thought everything was off. I feel cheated....

You are right - I think the weight is with a person in it .. 175lb .. They corner balanced by adding a person with similar weight to me in it. I will call the shop today to confirm.


Also regarding TC... In a 2013 with PTM and Mag Shocks, I replaced them with coilovers and added F55 simulators. This threw the 'Speed is limited to 158mph' error.. and allowed me to turn TC on and off but not turn off AH. To turn off AH permanently (I hate AH), I unplugged the steering sensor. This disabled AH. So now on the street I can run with TC on (AH always off), and on the track with the press of a button I can turn off both AH and TC. Which is what I want.


The other benefit of removing the steering sensor is you don't need to run tPMS - as in if your TPMS sensors are broken or missing, AH won't intervene.

I think mine is limited to 158 because I have f55 mag shock disabled. If I wasn't running f55 sims I would be limited to 80mph

Don't have the ***** to go over 158 on any of my local tracks so I am good for now.

Eventually I will get f55 and ptm programmed out.

Wow -5 camber on the front!

w00tw00t

yeah crazy huh - so this is confirmation that the HB camber kit (which has two settings for the lower control arm), allows you to run crazy camber.


It is now set to a more manageable -3 deg. now.

Maybe I'm wrong but, regarding your "after" measurements, isn't "negative toe" toe out? I can never remember because I align at home and never read shop printouts anymore, but that is what a google search turned up.

Is there a c6z model year where tc/ah off really means tc/ah off like my 2004 c5z?
I am looking to buy c6z soon.

LFZ

Maybe its just me...I have run TC/AH off per what it says on the DIC in my 08 Z...and it really does feel like everything is off.

There is a way to defeat the f55 without the sims.

ErnieN85

It will be all off until it senses a tire problem.................then it's back on

w00tw00t

yes I know.. I will get it programmed out in a month or so.

w00tw00t

maybe alignment gurus can jump in to clarify but I just went with the pfadt settings for a track car with r comps and poly bushings

Understood. The document lists that negative toe is toe in, so I was mistaken.

The button will turn everything off but the Tire Pressure Sensor System can turn it back on at unexpected times when there are sensor failures. Pulling the connector to the steering sensor prevents the EBCM from applying both front brakes to slow the car to 55 mph if a sensor suddenly stops broadcasting or broadcasts you have a flat tire.

The button will not turn off the most annoying DRP and VSES routines in the ABS. Those are the routines the eliminate proper rear brake bias, and refuse to allow any proper amount of yaw (in tight turns) if the brakes are on... in other words, they overwork your front brakes and force you to plow on corner entry.

Unplugging the Steering sensor seems to take some of the anger out of these systems by confusing them somewhat.

Bill Dearborn

I have never had an issue with DRP. I look at it as an advantage. Have never had an issue with AH when it was turned off either. For me pulling the steering sensor only provided freedom from the TPMS sensor issues. I can yaw the car any way I want with just the button pushed.
