Only question I have is with the bolt-ons for that car. Engine power wise, the edmunds article stated that the extra power from 333 to 350 comes from a new cat-back exhaust and ECU tuning.
Does that mean that with the Stillen exhaust and the exact same aftermarket tune from Uprev/Technosquare yield the same WHP numbers as a normal 370 in theory?

I can only imagine what it stillens exhaust would add if you threw in a tune.

I'm not interested in getting involved with this silly argument, but just to note, the diffuser on the e46 M3 is not very functional and is mostly for look.
For the 911, it's difficult for porsche to make a proper diffuser due to the placement of the engine. The 911 GT2 is only suppose to make 57lbs of downforce at 100mph.
Which diffuser makes more downforce though really doesn't matter especially on the street. If one had a track-oriented car and wanted to improve aero, the car would be super low with a splitter right next to the ground, have a huge wing and canards among other things, but alas there's only so much you can do for a street car.

The cars I displayed were to show integrated diffusers, not which were more effective than another.
We all know what real track cars would be setup as and that we are dealing with cars more inline with the street. It's for that reason I found it so hilarious for some to go put down another car to make theirs seem better without an ounce of proof to back their claims.

This "silly argument" aside, just to add another note, that's not the regular e46 M3. It's the e46 M3 CSL. I'm sure you can read about its weight, power, suspension, and aerodynamic advantages it has over the regular M3 if you do a search.

I'm not supporting anyone's point of view in this thread, just making comments about those specific cars.
The M3 in question is a vorsteiner display car with CSL replica parts. Vorsteiner makes quality parts, but in this case, replica parts nonetheless. I'm quite familiar with the CSL, but honestly the main performance difference between the CSL and a regular M3 is in the tires. This is common sentiment if you read up on the CSL. The diffuser portion on the M3 looks nice, but is really not very functional. If anything, the CSL trunk may add downforce, but the diffuser, not so much.
I did not mention the F430 in my last post as it has much better airflow compared to the other cars (not familiar with the F40 in these terms). The F430's airflow with it's relatively flat underbody and diffuser is superior to the other cars posted IMO.

From the Edmund's Nismo 370z test
The Nismo's bodywork also features a new, larger rear wing and a functional rear aero diffuser. All the body changes combine to create 150 pounds of downforce at about 75 mph while generating less aerodynamic drag than the Nismo 350Z.
Nismo 370z drag co .300
As for specific rear axle downforce at 75mph, it was stated (by Nissan) the Nismo 350z produces "more than" 33 lbs while the Nismo 370z produces 35 lbs. All negligible but that all the more proves that all that ranting about the Nismo 370z's parts being "less-functional" than the Nismo 350z's was nothing but hogwash/********.
EDIT: Can't leave StoneZTech out of it since he was the one who started the whole "Nissan killed the air management" shenanigans.
Car is nice, but remember the 350z NISMO is still true Super GT model.
That 370z NISMO is not, the 350 NISMO RS and Super GT 350z NISMO that $285,000 ver. I would keep my 350z NISMO.
The 350z NISMO has that nice track setup look and that is what I want. the 370z NISMO looks like they killed all the Air management of the car for all the cry baby's out there who new nothing about why they made the NISMO 350z body the way they did for high speed grip at the track.
Sorry but I would not trade my 350Z NISMO for NISMO 370z.
If I want a sexy sports car I would by a G37. REMEMBER THE NISMO 350z has SAME BODY HAS 380RS just Diffrent Eng setup!

Change the subject
I can't find anything that states whether the new Nismo 370 has welded seams. Could be a definite perf difference between the two Nizzy's (350 & 370).
I remember an article stating that the Niz 350's welded seams are a big contributor to speed on the track via handling.
