Well, I've had a build diary on Mazdas247.com in the Motorsports section, but I figure we can use the content on MX5ATL. Let me know if y'all want and I can go and find my build from last season. Details on that include everything from your basic shocks and springs, to a clutch job, dropping the trans a couple times, etc.
But I digress. I'll move this thread mostly in its entirety, not including comments, so forgive me if it seems a bit disjointed. Enjoy![hr]

This evening I realized that over the course of this season, I'm taking nearly 100 lbs out of the car. ~ 60 lbs of roll bar, ~ 30 lbs of power steering, 6 lbs of wheels, a couple pounds per seat, uber light weight lug nuts... That's damn close to 100 lbs. When I set out to do these things, I really didn't think about the impact that would have. When I got it corner balanced at the outset of the 2008 season, it weighed in at respectable 2130 lbs. Doing a quick and dirty number crunch, taking 100 lbs out of the car is shaving about 4.7% of the weight at the beginning of the season. In a car with ~105 WHP (give or take), that's pretty darn significant.
Original power to weight: 2130 / 105 = 20.28 lbs / hp
New power to weight: 2030 / 105 = 19.33 lbs / hp
Given those 'goal' numbers, I really want to see what we're taking off the car. In an effort for accuracy, I will hopefully be picking up an accurate postage scale this week and weighing what has come off so far, and will continue to do so over the next couple months as the pounds drop. Once that's done, I can start on the engine rebuild and really see what this ol' girl can do!
