Default c6 corvette.. how can I tell if it's z51 optioned?

Where do I look? I looked in the driver door jam for a sticker with a list of codes but the only sticker there is the Corvette, bowling green, Kentucky sticker. It's a 2005 corvette and I'm about to put a for sale ad in the classifieds.. I'm just not sure whether or not it got the option

right.. I knew about the drilled rotors, but it has 96k miles and isn't sporting the stock rotors anymore. Is there any other way to tell without me crawling under the car to look for the cooler?

Other than looking at the rotors, if it's a Z51, it should be on a plate in the glovebox. I stumbled across that in my Dad's '07.

If you have been under the car a quick way to tell is to see if the transmission has a fluid cooler built into it. Z51 cars were the only base model corvette that had a manual transmission fluid cooler setup.

Or call your local GM dealer and give them your VIN. They can look up all the RPO information on the car.

It can have the F55 brakes (larger drilled slotted rotors) without being a Z51. My 08 has F55 brakes but not a Z51.
