OK, let's talk about tire sizing.
I'm having a ton of trouble figuring out what to go with. Wheels will almost certainly be 15x7 TRMotorsport C1Ms. Tires will almost certainly be Star Specs. So the size is where the issue is. I know that testing has shown that 195 is the best width for performance on our cars, and it'd mean that I wouldn't have to worry as much about fender clearance as with 205/50/15s. The issue is that 195/55 is like a 1.7% larger diameter, and 195/50 is like 1.5% smaller. I'm worried that this might be enough to create a difference in acceleration or fuel economy, whichever way I go. 205/20s would be almost exactly the same outside diameter, but will add weight, might add cost, and might be a fender clearance problem.
Mazdeuce, how are those 195/50s doing as daily driver tires? Has there been any hit to your mileage from the extra rotations? Is the diameter difference even tangible vs the stock tires? Do you think it might be worth considering 195/55s instead, since the car is 90% a commuter, and the 195/55s are on closeout on TR for $99 a pop?
Oh, I've got the springs and will be putting them in on Sunday, by the way. Need anything measured before they go on the car?
In other news, I finally found a shift knob I like. It's from Garage Star, who's local to me and who specializes in Miata and AE86 stuff.

What's cool is that it's got a really nice spun metal finish, but is so finely machined that it feels like polished chrome in the hand. What I'm thinking would be really awesome is to get one of the 2.75" extensions he sells, and then a short shifter (when they come out) to make up for the extra throw length.
The guy who runs Garage Star is open to making some Mazda2 stuff if anybody can think of anything useful. He mostly does stuff that's cut and bent out of sheet metal, so various kinds of brackets and stuff. If anybody has any ideas for stuff he could make, I'll pass them on.
