Anyone know if a c7 has to have tpms on slicks? If so will car run right during hpde events? Just started hpde this year. Thanks.

I would imagine so. I had tpms sensors fail in my C7 and it screwed up the ABS system. I'm pretty sure they work in conjunction with each other...

When I first got my C7Z I used a set of wheels and Hoosiers that I had left over from my C6Z. Of course the C6Z TPMS won't work with the C7 system so I basically ran without sensors. Didn't have an issue. None of the BS that used to happen with the C6s where missing sensors would limit speed in turns to 55 mph.

I finally had some C7 sensors installed when I changed tires but really haven't noticed any difference between when the car has sensors and when it doesn't (other than I don't have to reset the warning message). Even with the C7 sensors it some times takes several HPDE sessions before the car starts to recognize the sensors in the track wheels Vs the sensors in the street wheels.

I can say having the sensors active has helped me two different times. Two separate times at VIR I picked up some metal in the left rear causing a rapid but not immediate air loss and the system alerted me in sufficient time that I could get the car to the pits.

I saw this TPMS disable trick in this magazine article, it is at the bottom of the page
and labeled "The “Easter Egg” Mod" , haven't tried it, but sounds functional.

Bill I had the same think happen once at VIR same position. I was going into the upper esses and noticed the pressure dropping and slowed down. I felt it before I saw the pressure drop but I wasn't sure what it was. I ended up coasting through in the 80's instead of 120's. I wasn't 100% sure something was wrong but I always keep the tire pressures showing in the dic. On another note whatever it was that I ran over went through the liner behind the wheel, bounced back up to the top of the fender, and put two bulges/cracks in the top of the fender. The kent moore tool is less than 100 bucks and, for me anyway, well worth it.

Our C6 track box that eliminates performance limitations due to absent TPMS sensors should work on a C7 as well. I just spoke with our manufacture about it last week but haven't had a chance to test yet. Let me know if you run into issue/world like to test it for us if I don't have a chance to verify compatibility in the meantime.

Thanks!

My track wheels came with the wrong TPMS and I ran two events with no noticeable difference in performance. The tire inflation dash light was on and the digital tire readings read "--" for all four wheels. I just dismissed the warning and carried on. I have the correct TPMS installed now but I think it's a nice to have as opposed to a got to have thing. The car ran fantastic either way.

Thanks Everyone for your input. Bill I'm of the same mindset as you and knowing where your pressure is at is well worth it just in case a tire does start to run low.

You've been lucky with it switching over. I have three sets of factory wheels with factory TPMS sensors and sometimes it works fine and sometimes it takes a tool to make it work at all. I always swap brakes and wheels and road test it before heading to the track. I had it throw a code one time for the rear axle and the only thing I had done was switch tires. That's when I bought the tool.

2015. I usually swap tires for each event but I have no idea how many times I've done it. I had to use the tool twice so since then I just go ahead and use it unless I forget
