Here are a few preperations you should do to get the most out of your car in its stock configuration: Some preperations will gain more than others, and each will be hardly noticable by themselves. When you combine them all together, you will get noticable gains in ET and MPH, as well as the car feeling faster.
Up your timing. I had the best results with 16 or 17 degrees of initial timing. You want to do some testing to see what gives you the best results. Do this on the track, not the dyno. Once it stops going faster as you bring the timing up, back it down one degree.
Pump your front tires up hard. I usually pumped them 2-5 lbs higher then the max stated on the tire.
On a lower hp car, you may find the car goes faster with your rear tires pumped up harder than you would normally run, not as hard as the fronts. This goes against the norm, but a stock miata has so little power, that you actually get more from less rolling resistance than more traction. It can also make it easier to control the amount of wheel spin to make the car move forward sooner. This depends on track conditions. If you find yourself bogging, keep raising the tire pressure.
You will need to practice your launches at a particular tire pressure. Do not assume that if the car blows the tires away that the pressure is not right. You have to learn how to modulate the clutch and throttle.
When you launch the car, come out at a high rpm. Release the clutch and roll the throttle. Practice practice practice.
Change your tranny oil to the redline MTL. You will be able to shift faster. I shifted with throttle to the floor. Do you have a 5 speed or 6 speed? I made hundreds of passes in my lower hp car and have not broken a tranny. It is up to you if you think you should do this. I have a 5 speed.
When I went to the track I always pulled my A/C belt. I had a measurable improvement with this mod, and it takes five minutes to take off and put back on.
I always pulled my spare tire and jack out. Sometimes I pulled the passenger seat. It makes a measurable difference. It is just a few minutes work.
I usually pulled the air filter out at the track. I remember it making a small difference. Depends on what you have now. Try it to see if it works.
These are the first things I did to my bone stock car. Some of it is a bit of work, but is worth it when you see a real gain.
