As best I can figure it the parts are as follows:

1994 Mazda Miata which has a 1.8L and we are assuming a LSD.

Engine:
Exhaust Street
Oil and Cooling Street

Platform and Handling:
Brakes Street
Springs and Dampers Race
Front Anti-Roll Bar Race
Rear Anti-Roll Bar Race
Chassis Reinforcement and Roll Cage Race
Weight Reduction Street

Drivetrain:
Clutch Street

Tires and Rims:
Tires Sport
Upgraded Front Tire Width to 205/55R14 (to be upgraded to 15" rims later)
Upgraded Rear Tire Width to 205/55R14 (to be upgraded to 15" rims later)
Rim Style your option as long as they are not lighter than Team Dynamics Pro Race 2 option
Front Rim Size 15"
Rear Rim Size 15"
Total Performance Index Should be D299
Any performance upgrade of any kind that is not listed above is not allowed.

Tuning Specs:
Tires ANY pressure is acceptable(a good starting pressure is 35psi)
Alignment ANY
Anti-Roll Bars ANY
Springs Front 700lbs/in Rear 325lbs/in, Ride Height ANY
Damping ANY

"Benchmark" Specs should be:
0-60mph: 8.115*
0-100mph: 23.547*
Top Speed: 129.7mph*

Braking
60-0mph: 114.4ft*
100-0mph: 315.0ft*

Lateral Gs
60mph: 0.97*
100mph: 0.94*

* actual results will vary slightly depending on specific tuning options, but these baseline specs should be close.

Hey Newton,

We run a very competitive D350 Miata series on a weekly basis. If you're interested in joining us let me know. We're running a race tonight too - if you want to join, we certainly have the room. We race clean (minus the whole bump drafting thing) and we have a wide variety of drivers with a varied skills/speed, so you'll pretty much always have someone to race with / compete against. My account is kudomaster43.

Anyone else here is also welcome to join, message me or add me on live - and we have Oka cars you can "rent" (for free) if you don't have a Miata pre-painted :).

Also, if you want to see how our spec compares, I beleive there is a current setup of our spec on my storefront, available for download.

Hope to see some new faces out there tonight.

I have followed all of these specs perfectly and my Performance Index comes to 306! I think I run into the problem with the Wheel size and Tire Width, when I do not upgrade any of the tire width of wheel size it is at 299. Can you re-clarify?
