Driveway Specifications

Will need to replace the hardtop in my driveway, and since they will need to regrade anyway, thought I should get it fixed right.

Currently, am scraping in the front when I enter the street, 2004 stock suspension convertible.

Does anyone know the "grading specs" for a drivway, which would prevent scraping. I would assume it would be inches of drop over inches of run, but I am obviously not an expert.

Thanks

The easyist way to determin this angle is to stretch a string under the car from the point where each front tire makes contact with the road. Be sure to do this on a level surface. Take a yard stick and place one end on the string. (the end starting with 1 inch) Raise the other end until it contacts the air dam. Now, simply measure the height at the 1 foot mark on the yardstick and that will tell you exactly how much rise per foot you need.
