Considering Disabling ABS..any thoughts?
I run a C-5 Z06 at MSR Houston on a regular basis and have been plagued by very inconsistent brake feel and activation of ABS. I was curious if anyone who tracks their car or races has tried to run with the ABS fuse pulled? Thanks!

Let me tell you from my own experience that you dont want to do that.I think the brake bias is done with the computer, some one correct me if I am wrong. I co-drove a zo6 in an enduro with no abs and it was not fun. One more thing you might want to consider. The abs will keep you from flat spoting your tires unless you get sideways, and if that happens the abs is the least of your worries.

On my 2000 C5 I had the DRM brake bias block and it really help the rears work. based on pad wear and other indicators the rears did their job.
On my 06 Z06 the rears don't do squat, which makes the front pad wear more of an issue. four sets of XP12 worn out on the front and the rear XP08's only wore to less than 50%
GM bring back the manual bias spring!

It will still work fine if you dis-able it, but you will likely need to install at least one bias adjuster. It will take a good bit of track testing to get the bias close, but it can be done.
HOWEVER, the factory system is awesome, you should really correct the problem. Even if you have to replace every wheel bearing, track down any damaged/loose wires etc, you'll go faster with it than without.

(my code says wheel speed sensor, so that seems like a logical place to start
)Thanks.

the wheel speed sensor is INSIDE of the wheel bearing, so if you are getting a speed sensor code, you either have a bad sensor, or a bad wire reading it.

With all do respect, I have to disagree with you. It is a handfull in race conditions. The car was always on the vurge of brake lockup because of not being able to controll the bias. Is it worth installing a proportioning valve? Thats up to each person IMHO. I think it is one of the best perfomance tools on the track short of more horsepower.

At Spring Mountain, they did an exercise with and without the ABS. The ABS clearly out performed the drivers ability to stop the car. This included wet conditions.
I found if you are running with all safety systems on and are using track pads the Abs goes nuts. Run in comp. mode or all off and the Abs is much less intrusive.

somewhere around 04' was when they turned the brake bias job over to the computer. which IMHO in not good.
On my 06 Z06 the rears don't do squat, which makes the front pad wear more of an issue. four sets of XP12 worn out on the front and the rear XP08's only wore to less than 50%

The CPU will do a better bias job than you will do in a lifetime of testing and screwing with it. It has a very sophisticated algorithm and it update that in nano-seconds for the precise condition at that precise moment in time ... manual settings fail by comparison. I have manual in my SRF and would love to have the Vette system!
