had a 95 Miata with suspension work and bolt ons. i miss that car. so much fun to rip thru the twisties. sometimes i wish i would of kept it and went forced induction, as my biggest gripe was that it was under powered.

The great thing about the car for racing is that I've made about a dozen money shifts through the years and it's still going. If I do manage to blow it, I can get a known good running motor (probably better than mine) for about $600. Car needs a transmission now.

It's the most popular car in the DC region, so lots of support and close racing. Only one or two other classes have more than a dozen cars in the race. Mine usually has over 40. The downside, lots of cars and close racing leads to this:
