I pretty much decided to get the set of 18x9.5 z06 style rims with kumho 712s off ebay, as the price is hard to beat. Does anyone have them? Anything i should know before i put my money down? How heavy are these wheels comparing to OEM z06 rims? i know the stock size tire on the rear of z06 is 295x35, while these are 275x35s, so is that safe did they just stick the biggest kumho there is on it and let us worry about it?
thanks

275/35ZR18 tire is perfect. Same OD as stock.

Your other questions I can't answer.

The 295/35 is designed for a 10.5" wide wheel.
