TPMS Sensors for drag pack
I recently went from a 20” 555R drag radial on 1LE reps to a 17” 555R2 drag radial on Racestars.
I liked having launch control because it really helped making runs on non prepped roads more consistent. My 17”s don’t have tpms sensors can anyone recommend some inexpensive TPMS sensors that’ll work on a Racestar. Also I’m assuming that’s why launch control isn’t available anymore right? Any feed back would be greatly appreciated. |

It's very likely that the TPMS sensors are causing this since the fronts are there but the rears aren't. Adding TPMS to the rear will probably work but you might also run into the same issue depending on how low you set tire pressures. Another few alternatives are either to unlearn the front sensors so the car isn't registering any sensors, or follow the instructions here to bypass the chassis control systems check for TPMS https://www.corvetteforum.com/forums...ms-how-to.html

Id be interested to hear if the TPMS caused the launch control to be inop, my answer would have been that lack of TPMS I haven't seen that affect any other system on the car other than the dash light would illuminate. I've run winters w/o TPMS and it did nothing to the car.

They work great. Schrader is the OEM for the real GM sensors, I've been using them on all my race wheels without any problems. I had issues when I tried to use the Chinese knockoffs from Amazon, definitely not worth the trouble when the real Schrader sensors are reasonably priced.
You'll want to pick up a EL-50448 TPMS relearn tool if you don't already have one. I use this one, it's only $10 at Amazon- https://www.amazon.com/gp/product/B06XVR85N7/ Edit: As others have noted, the system needs to see all 4 sensors or needs to see 0 sensors. Anything in between is a fault and it will not permit you to disable TC or use PTM modes. (unless you do the 6-key-press noted in the Corvetteforum posting...) |

I always drive with traction control off it doesn’t appear that not having sensors in the rear is creating any issues with turning traction off it still says I turn it off. I do struggle more to get traction now however. |
