TPMS Question
I just ordered new wheels for my car and I dont know how the sensors attach inside the wheel. Im wondering if its going to be a problem for the tire guys to attach the sensors and whether they can screw it up, say they cant do it or charge me an arm and a leg to mount it. CCW said they can mount new ones prior to shipping but I dont want to pay for new ones when I already have them. Any suggestions welcomed.

Here ya go!!!
Pics below show how your sensor mounts in the OE wheels. If you got CCW wheels they will accept the sensors in exactly the same manner.
You say you have sensors - they should be the same sensors you see in the pics below (GM Part# 25758220, which is molded into the case - you might be able to just make it out in the pictures). The sensors are made by Schrader, and they are available directly from Schrader distributors as Schrader Part# 20076, which looks exactly the same except it's red.
Every decent tire shop should be able to work with sensors these days, but take a look at this thread and you'll see they can definitely screw up and bust a sensor.

Are these track wheels that you'll be swapping on and off regularly? If not, you'll just need a one time relearn procedure done with a sensor/TPMS reset tool by the tire shop.
If they are for track wheels that you'll be swapping on and off regularly you'll probably want to buy your own tool.

Most stock Corvette wheels have band sensors. Those attach with a stainless strap that runs the circumference of the wheel. They do that for clearance purposes. Unfortunately, it also means it'll get cooked should you get a flat tire. Check your wheels for the application first. It's very obvious, a black rubber valve stem means you have banded sensors. A hex-shaped metal/plastic looking stem means it's a normal sensor. If it's the screw-in type, make sure you don't torque it down more than a little bit past snug, just enough to prevent leaking. Too much and it'll crack. Also, if it's the screw in type, check the rubber grommet inside and the nut outside for corrosion or fatigue. They tend to leak due to that. If it looks ugly, you should be able to pick up a rebuild kit relatively easily. It should come with a new nut (11 or 12mm...I can't remember), grommet, cap and valve core.
If it's the banded sensor, all you need to worry about is keeping it on the wheel and don't let them crack it at the tire store. The sensor is almost always located 180 degrees from the valve stem when it's band-mounted.
I work at a Discount (America's) Tire store, so I definitely run into those things on a daily basis.
