Grand Sport Very Low
I brought my car in for an oil change. The dealer said they have such trouble with my car on the lift. It is the lowest vette they have serviced. The weird thing is I bought it brand new from this dealer and have done nothing to it. Are the grand sports lower ? Can I raise it up somehow as I am always scraping the front .

I've been looking into the "Ride Height" issue and measuring the official "Trim Height" under my car's suspension, and the ground to wheel well arch on many other C6's.
I've discovered three things:
Most C6's that have more than a few hundred miles, and never lowered; are still lower than the official specs. Some are a lot lower.
The offical specs have changed from year to year. The numbers for a 2006 are different for a 2009 and different again for a 2012, even though the narrow body cars are made the same.
Checking the height requires the car be up on an alignment rack, and using a special GM tool that measures the height between two points on the suspension under the car. GM has no numbers for easy to use measurements like frame height or wheel well height.
Also, if you go to raise the car, each turn of the bolts will initially give you about 3/8" increase (!), but after about 200 miles that will settle down to about 1/8".

Anytime (which is next to seldom) the car is to be on a lift I take 12" boards to assist the dealer and I put it where they want it. The air dam is made to scrape and replace when necessary.

Steer away from the dealership for simple maintenance like an oil change. I take mine to a shop that has a "pit" for oil changes. This eliminates the need for a lift.
