I finally got my M05 Miata built and ran it for the first time yesterday. I added bearings, the plastic oil filled shocks, Tamiya alloy steering posts and Tamiya alloy steering rod.

I'm just running it in the street for now and with some Shimizu medium tires front/rear, stock diff and shocks set up with blue front, red rear springs, 2 hole pistons front/rear and Associated 32.5 oil front/ rear, the car handles great. Feels very stable. I can tell that coming out of corners it is "diffing out" but it is not of huge concern for me since I am not racing this.

For anyone who is curious about these, get one. Fun and easy to build. Fun to run even with the stock electronics.
