The dataset for window removal analysis in the miata with the outlier laps removed.

The hardtop on the Miata is one of my targets for weight reduction on the Super Touring 6 Miata. During the last round of extreme weight reduction on the racecar, I did some testing to try and determine what effect, aside from an 11-lb weight reduction, running without the rear glass would have...

Getting the Super Touring 6 Miata down another 130 pounds is no simple task. In part 1, I laid out a plan of attack that I started at the most recent Nashville Superspeedway event. I brought my scales to document the weights, and although I may have looked like a maniac with a Sawzall in the...
