If you want to look at 0-60 (which is a funtion of how hard someone is willing to launch the car) the S2000 runs consistent 5.5's with a good driver and the 8 isn't even in the high 5's. The only performance number that the RX8 wins in is braking by 2 feet from 60.

As far as looks the S2000 looks much cleaner, it doesn't have crazy looking bulging fenders, ugly altezza tailights and a large mouth bass front bumper.

By the way I have a 05 Winning Blue RX8 6spd sport ******** so go your lastest motortrend magazine and smack yourself in the head for me will you
If you don't like how it looks why did you buy it....or you dont like anything about it.....again why did you buy it?

I am not sure if anyone posted this yet but here is the motor trend article comparing the rx-8, 350z, and the s2000. People who choose to ignore the first few pages (which just show motor trends placing for the cars) should skip to pages 5-8 where they post the actual test data. The data goes along with what many have said: the rx-8 isnt as fast as the s2000 and it doesn’t handle quite as well but it is NOT that far behind.

http://www.motortrend.com/roadtests/...son/index.html

In my opinion they are both great cars. My good friend has a s2000 and I love his car, however, I wanted something that would be more forgiving as a daily driver. To me the RX8 was the best of both worlds and I am very happy with my purchase. True car enthusiasts shouldn’t bitch and complain over what car is better but rather accept each car for what it is. Life would be boring if everyone drove the same car. Different strokes for different folks.

It's a far fetched claim...I didn't say it, like I said that's from PTS' own claims as to the purpose of using the carbon fiber driveshaft, yet the point still stands...the carbon fiber driveshaft is not used to achieve lower yaw moment. It is to achieve a more stable driveline, and to have less unspring weight in the transfer of power...resulting in as mentioned, better response from the drive wheels.

PST offers both steel and 7075 Billet Aluminum yokes.
In drag racing applications - a better 60 Ft. time.
ET's have been lowered in some cases by as much as .120.
In stock car racing better control out of corners is the result of the torsional spring rate.
In road racing smoother shifting and better durability of transmission and differential have been reported.
Tested on Cobra's at 180 MPH on Dyno with no vibrations.
A much greater safety factor - carbon fiber will return to a fiber and not create shrapnel under the car, as would aluminum or steel shafts.

these are the purposes as stated by pst a reputable carbonfiber driveshaft manufacturer. no where is yaw moment mentioned...it only provides better power transfer with mimial friction, drive train loss, vibration, and better reponse. yaw moment being a benefit of this component is another truthless statement that you've pulled from your ***.

That's all marketing gimmick, but hey they're pluses so I won't argue with that. But you proclaiming to be a physics scholar should realize that if a diveshaft has more mass it's going to resist change in motion more.

Why are you guys comparing the S2000 to the RX-8? they are both in different cattegories. Compare the 8 to a Accord or a TSX, then the miata to a S2000 then it will be a valid argument.

Last time I check my insurance says a seddan and the 8 has 4 doors. Actually let look outside real quick.... yeap the 8 still has 4 doors. The RX-8 actuall competion is BMW 3 series. why people think it should compete with the S2000? Because what the RX-7 left behind.

^ i don't think i can agree with that, the 8 is def marketed against the 350z, s2000, mustang, and so for (plus i agree with the 3 series.) But the accord shopping probably wouldn't test drive an 8 (ignoring what the insurance groups it into.) the evo and sti are 4 door, tsx's shoppers aren't test driving them.

So you're going to make comparisons based on the number of doors and seats on a car??? Last time I checked the 8 wasn't classifiied as a sedan either. A more fitting comparison to the Accord would be the 6 and camry.

Okay I was literally aiming to the accord but more aiming towards a sports SEDDAN. Like mention above STi, EVO would make a better comparison but not even close to the luxury factor of the 8 so a Legacy Gt would be a better one but that put it on a bigger car comparison (legacy is a mid size seddan). But 350z or other 2 seaters cars, yeah okay, quit being in denial and accept that you drive a seddan. BTW car are classified by the numbers of doors and body style, not by its perfoamnce, or what your you call a Trail Blazer SS? A sports car also?

Driveshaft weights are not going to affect change in motion/momentum so much as their locations on the vehicle. They are always going to be located centrally in the overall mass of the vehicle inbetween the fulcrums being the two axles, and counterbalanced among other components, thereby achieving the desired weight distribution. Change in motion centrifugally speaking is based on leverage, and in this particular case leverage is very small due to the location of the leveraged mass...in the center. Note both Honda and Mazda's placing of the entire driveline between the two axles (front and rear.) Driveshaft has little to no effect on yaw moment.

What in God's name are you talking about? I'm not even going to try and respond to the edit you've made because you make absolutely no sense. I'm gonna try and recover the brain cells I've lost reading that post.

I have to disagree...the Mazda RX-8 is clearly marketed against the 350Z. Some of the marketing ploys are the half doors. The car is considered a 4 door coupe on my insurance card. Not a sedan. It goes further than just comparing number of doors...you have to consider suspension types, road manners, driver orientation and market niche. The RX-8 is most similarly compared to a G35 than any other vehicle, but the price points are a little too different for them to be in the same category.

I guess we alll have different opnions about cars but RX-8 is not a sports car, I can tell you that for sure. So I don't think comaparing it to a convertible 2 seater car is not fair. would you compare a RX-8 to a Corvetter?

So insults aside. I put my opinion (which is all it is and I'm free to do it even you like it or not) down.

To be technical about the deffinition about coupe though

Ok shaolin man time to take you to school: Go outside and pick up a 6 foot or so 100 pound log and try to twirl it between your fingers and then try the same think with a 6 foot long 1 pound broom stick. Physics scholar my

Also, with the the 8 the driveshaft is more centrally located because the engine is set further aft in the chassis because of the rotary's shorter longitudinal axis therefore, less need to counterbalance .

you can't argue saying the 8 is a sedan, it isn't about us being in denial, but honestly step back and look at the car, give me ten strangers and not one will call it a sedan.

Yes, with the 8 the driveshaft is more centrally located because the engine is set further aft in the chassis because of the rotary's shorter longitudinal axis.
your comparing the mass to the strength of the average human, of course its a huge difference. to the rotation of a 3000lb vehicle its nothing.

Wrong. The transmission in the 8 would not allow for such a location. The Renesis is still mated to a transmission, who is in turn mated to a gearbox, and driveshaft. By your reasoning, the transmission of the RX-8 would be located under the dashboard.

You fail to realize the fulcrum points...the driveshaft is transfering motion from one fulcrum point to the other, on each end. Leverage is transferred inward not outward from the center of the car. The purpose of the car's overall handling dynamics through chassis design and suspension is to transfer weight from one side to the other...not to concentrate leverage on a centralized location and spin the car constantly.

You don't spin a car down a track.

Your reasoning on rotational inertia is correct, however it is improperly applied in this sense. Your reasoning would place the fulcrum i.e. axles and wheels in the center of the leveraged mass in question.

i can completely agree with that, plus i can see your point, but visually (spelling) speaking its hard to call it a sedan when there isn't any other sedan visually close to its shape.

^^^I agree...the RX-8 is one of those cars that refuses to conform to conventional ideas.
