I may end up splitting it up into a 60 - 30 to get an idea of aero changes and a lower speed one to judge rolling resistance.

Also, if all I'm looking for is a rough estimate to check how mods change the car I could also just use a stopwatch to time speed change from 60 - 30 and then use the car onboard average speed calculator to get avg mph and translate to ft per second to come up with a distance.

For that though I would have to find a flatter place to test. Also decelleration would not be constant.
