I couldn't resist and posted in a beginner track day thread
already, but here is my intro post.
I bought my '92 red C-package new based on the car magazine reviews at the time. After buying the car I realized that the nearest interesting road is about 150 miles away on the other side of Austin in the Texas Hill Country and probably should have gone for something with a lot more horsepower.
The car is still completely stock and mostly original except for a few dealer installed Mazda parts done before delivery, including the bling bling chrome cam cover:
The car was "retired" in 1995 or so and kept for driving on nice days. It has about 35K miles.
In 2007 I bought a new Mustang GT to do track days because the Miata's lack of hp didn't seem like it would be much fun. I did track days in 07-09, NASA Time Trial in 2010, sold the Mustang and bought a '98 Camaro for the NASA CamaroMustangChallenge in 11-13. I sold the Camaro and didn't drive on the track for a while, other than the urban myth "HPDE in a rental car" last summer.
I looked at getting a Mustang for NASA TT but decided that the S197 Mustangs weren't really competive below TTC or maybe even B, and I didn't want the extra cost of the faster classes. So I plan to build the Miata for TTD.
I am thinking of Forced Induction with 150-160 rwhp and a < 2400 lb weight for a TTD base class. So I will be posting questions about the best TT weight, tires, aero, wheels, cooling, shocks/springs etc.
much shorter summary
I will be building a '92 Miata for NASA Time Trial and will have a lot of questions!
