Yes, their main focus seems to be the overflow (at least a pint), the carburetor return spring (double) and the battery tie down.
The seat restraint rules are based on time. I have only a lap belt. There are special rules for convertibles. You might be required to wear a helmet and possibly gloves both of which are available for rent at a nominal charge.
The rules say the vehicle can not leak fluids. The staging lanes however, look like the parking lot of an auto parts store. I think if you do not have an active leak you will be fine.
