On a seperate note, I like the idea someone had of allowing a modified class to run along with the spec cars. It would definitely broaden the series and make it easier for others who already have a prepped beyond spec car to participate. I was even thinking if this series took off, it would be cool for NASA in a few years to have an all Nissan race class, but thats just too greedy of us I suppose.
If you want to race a Z33 modified beyond Spec Z rules, NASA will have a class to participate in. At the '08 NASA Nationals I raced my T2 350Z in Performance Touring B and had Daytona Prototypes, V8 late models and Legend Roadsters in my run group. Believe me, that's a broad group of cars to "participate" with.

In the oem location's front and rear, a pretty high percetage is leveraged out. On a true coilover rear setup, the spring is almost directly connected to the wheel hub. So it almost transmits 100% to the wheel.
To calculate wheel rates you use the following motion rates
Front .688
Rear oem location .649
True coilover rear location .97
Example
Nissan Motorsports T2 springs
Front 690lbs x .688 x .688 = wheelrate 327lbs
Rear 690lbs x .649 x .649 = wheelrate 291lbs
Hope that helps

GTC01 is also available in 18x9 +18 and 18x10 +22, much better offsets for the Z, but heavier pounds a wheel than the RPF1.
a matching set of wheels in the proper offset, weight etc etc may be a PITA to get. I can see most people on RPF1's with 13mm spacers. The rules would be much easier if it was 9.5 max front or 9.5 front and rear.
Rota has a few sets of wheels available. Grid , boost, SVN and DPT http://www.wheeldude.com/wordpress/

You could always splurge for some made-to-order Braid wheels? They even have a contingency program. You can find them here: Braid Wheels
On a seperate note, has anyone confirmed if the 07-08 Nismo 350Z is an acceptable platform??? I know they post the 07-08 350Z, but there is nothing specific about the Nismo model. Granted you'll be removing a lot of what makes it a Nismo model to make weight, but some of the parts can sell for good $$$$ on the used market plus you get that awesome stitch welded chassis.

I guarantee you dont want to race your car without a full cage including door bars, particularly with the larger, heavier other cars that you will be foreced to race with. I've seen some pretty bent up totaled cars after being T boned at speed. You want and need as much safety as you can get. Thats where the first part of a large budget should go.

I don't know if I would want to gut and cage my Nismo when I could just sell it and buy a junked Z. It would be nice if you could run it just bone stock without having to put in race seats and a cage. If that were the case I would just throw some lighter wheels on, get it retuned with UpRev until it hits that 275hp mark and see how she does.

Has anyone else noticed that the prices have gone up significantly for 03-05? Last year and the year before I found several in the $6K to $8K range...now I am seeing them start at $8K and go up from there.
This isn't helping.

I have not noticed this inflection point. 2/3 years ago, I felt like bottom-barrel Zs were approaching $10k. If you asked me that today, I would have said $8k min for a clean one. Find yourself a salvage, and cage that mother. I think one can be racing SpecZ for $12-14k with a salvage Z. I hope you join!
