315mhz for USA cars, and some export cars like UAE, While most export C6 where 416Mhz for them instead.
Quick way to see what the car is set up for (and that your using the 2008-2012 TPMS, not the ones for 2005 to 2007), is look up the fob number on the back if it, to see if its 315 or 416 fob, since the tpms for your year, will match it in frequency as well.
So yes, for C6 4 different fobs and TPMS's, so you have the year cut off, then you have the 315 verses 416 for export cars.
And go with the Schrader tpms, since God only knows how long the oems have been sitting on the shelves/how aged out the batteries will be in the oems.
I bought OEM ones for my 2011 GS and they worked perfectly. I used the $10 TMPS programmer to program them. Its best to program the new sensors before they are mounted in the wheel because if they for some reason do not work you have to have the tires dismounted again. I got the sensors nuts and programming tool from amazon
