I started working on my car about 4 years ago although I didn't start racing until June of 2011.

99 Miata straight points classed
205 NT-01s on 8" 6ULs but will be on 205 RRs next +9 for RRs -7 for 205 +2
2400 pounds comp weight
99 Rebello 0 points motor with DPtune flashed ECU
CAI +1
01+ OEM exhaust manifold 0
Borla SM race exhaust and cat delete +3
OS Giken diff +3
Xida-S +5
RB front sway and 949 links +2

I'm currently running a 6 speed so that uses the last of my 19 points but I'll soon be installing a 5 speed. Not sure how I want to spend those 3 points.
I have poly bushings, brake ducts, front Sport brakes, adjustable bias valve, lightweight OEM shaped hardtop, stiffer engine mounts and will soon have polycarbonate windshield.

I think the driver and head mechanic are the weak links of the team. Well, the owner isn't spending enough currently either to keep up with these Hoo Hoo driving fools.

I thought you had to take points for sport brakes.


My Setup:
91 Chassis dyno classed (2360/123)
99 motor with MSM intake cam
stock 91 ecu with rpm switch for VICS
RB header
Enthuza car test pipe and exhaust
225 NT01 on 15x9 6UL +6
NB 4.3 Torsen +3
Xida CS 700/400 +5
RB hollow 1.125" front sway, MSM rear sway +2
ES Bushings
949 Endlinks
949 organic twin disk
coolant reroute
Koyo 37mm radiator
carbotech xp10/8
Lexan windshield

rear subframe brace +3 (will be removed at next alignment)

probably try to register it as a '94 so I can add oem subframe bracing and 1.8 brakes.
Planning on going down to 205 RR on 15x8 at some point and adding some aero.
ECU is also in the plan with a squaretop and getting rid of my 1.6 AFM

Greenbaum allows you to class as a different model of the same platform as long as all the components that make it the other model will bolt to your tub and vice versa. Precedent was an FC RX7 turbo at nationals that was the n/a model with the turbo brakes and LSD, classed as the turbo. I did that at nationals with the MSM and promptly got 100lbs added to any MSM dyno class. (sorry!)

So any NB year can run Sport Brakes front and/or rear. Thus, classing and NA6 as an NA8 is OK. Someone could argue that a few of the studs welded to the bare tub are different but it's in the spirit of the rules so even at nationals no one will give you grief if your VIN doesn't match your PT form, provided it's on the same line or cross compatible as described above.

Along with what Emilio said, the 99 is classed from 99-05. 03-05 came with sport brakes on the base model therefore 99 can use Sport brakes or 03 can use reg 1.8 brakes. I can also drop an entire 01+ VVT longblock in my car as a no points mod but I can't drop an 01+ bottom end with a 99 head. I got permission from Greg a few years ago to run the 01+ exhaust manifold as a no points mod.

It's all about reading the rules.

ahhh, I didn't know sport brakes were ever base model. Not relevant to my NA anyways.

Yup. Option on 01. BTM from 02-05.

We ran Sport Brakes on all the T25 cars.

I will say, NASA rules seem easier to follow than SCCA's.

I'm a little confused, why don't exhausts and headers add points? Is it due to dyno-classing?

That's correct. A straight points classing car like mine has to count points for exhaust or aftermarket header. Part of the trade off of dyno classing is the ability to use more mods to shape your power band but you run a greater weight to power ratio. Emilio and Savington have been able to overcome that less favorable ratio.

Excellent. +1 for not knowing that Sport brakes were BTM. I assume you have to take the points if you ran regular 1.8s in front+Sport in the rear, or some other non-OEM combination?

Yes, read the rule book.

And then cheat like a mf'er because NASA will never tech you past dyno'ing you and weighing you after you come off the track.

Even at Nationals the PT tech is laughable.

I finished on the podium in PTB a few years ago, I was blown away by how little they checked. I was disappointed because my car was completely legal, I should have been cheated up...

I'm not sure I'd read it that way. The rules use the word "assembly" which to me in the case of brakes means corner. For instance, say running a Sport brake caliper with a 1.8 rotor - don't even know if that's possible - that would be a points mod because it creates a new assembly. I could be wrong in my interpretation, wouldn't be the first time.

The update/backdate rule goes out of its way to state:

Quote:
The purpose of this rule is to equalize similar cars in the same (or lower) class, not to allow the creation of vehicles that were never manufactured or homologated.
There were NBs built with Sport brakes, so upgrading a '99 to Sport brakes equalizes the two cars in the same class. There was never an NB built with 1.8 brakes in front and Sport brakes in back, and combining those two clearly creates a vehicle that was never manufactured/homologated.

For the same reason, you aren't allowed to run a '99 head on a 10:1 bottom end.

^^Wow, sounds like you've been talking to Greg. You're probably right. Re-reading the rules the other day got me thinking about this exact thing. Above is how I justified not changing my rears too. I'm still not going to until I can afford some new rear pads.

Actually, I'm just bitter because I'm taking the TSE 11.75/Sport rear combo off Rover this week. Swapping back to stock 1.6 brakes to get those 2 points back. :(

why not the 1.8 brakes? 1.6 calipers with 1.8 brackets and rotors.
