Big brakes Mean Big Wheels

Since our Miata is about to receive a Dealer Alternative Flyin’ Miata big-brake kit, we needed some appropriate wheels to clear them. The 15x7-inch Kosei K1 Racing wheels that we’re using on the street should clear the big brakes, but the stock 14-inch Miata wheels that we’re using for racing won’t work. We again wanted something light and easy on the budget, so we ordered up a set of 11.5-pound, 15x6.5-inch Rota Circuit 8 wheels from Atlanta’s RSpeed. Another cool feature is their $135 list price.

By the way, even before installation, the Dealer Alternative brakes are impressive, with 11-inch slotted rotors and aluminum Wilwood calipers. A billet, anodized bracket is included to mount the calipers to the stock Miata hubs, keeping this a bolt-on project. Look for before-and-after braking numbers once we have them.

We have also received word from Engineered Performance that our cylinder head is done and looks sweet. We hope to have it installed and dyno tested soon.

That means we can get plates from Hartgey right?

It was posted right about the same time we changed our name from The Dealer Alternative to Flyin' Miata, because the sub-brand of the parts was better known than the business name :) We're still officially The Dealer Alternative Inc DBA Flyin' Miata at one level.

Brakes have gone through a few evolutions, too. They fit more wheels than they did then :) I have a car parked outside that still has the original setup.

It's also kind of amusing to hear 15x7s described as "big" wheels.  They were in 2002, but 20 years later you can buy Miata-spec 15x11s easily and I believe there are some 15x12s out there. :)

I think it was big as in diameter. 15" was as big as Miata had ever put on the car from the factory at this time! At least in North America, there was probably some UK special edition with 17s.

I'm not sure how "easily" you can buy Miata-spec 15x11s, but there has been at least one production run. Unless Miata-spec just means 4x100.
