So I rolled my Miata across the scales at the San Diego Tour and the display showed 2168 pounds with 1/4 tank of fuel, helmet, camera, and soft top boot. This is with the 15x8 6UL / full tread RS3 combination and the quiet Enthuza NB Speeder muffler. Includes NB2 center console. Washer bottle empty and coolant overflow reservoir at 1/3 full.
Helmet 3.5
Camera 1.0
Soft top boot 1.5
Gas (2 gallons) 12.0
My Odyssey PC545 works great for a daily driver but at over 11 lbs I can save a lot of weight by going with a modern 2 lb. lithium battery. My complete exhaust is heavy too and it would be easy to save 10 lbs or more with a custom 97+db setup and Maxim header. Note the wheel / tire weights below also; I can save 18 lbs if I stay with the 195 Toyos / 7.5" 6UL. Subtract another 5+ lbs for Bogart, Volk, or SSR wheels.
2085# seems like a reasonable weight without going crazy, and in my estimation 2020# (after some thinking and rough calculating, and with the recent rules change regarding motor mounts, 2020# is probably not realistic. 2055# is closer, maybe.) would require maximizing the rules with aluminum shock assemblies, custom brakes and rotors, delrin bushings, replacement control arms, billet motor mounts, and so on. How much time and money do I want to spend? How bad do I want to win?
