My supercharged superwhite tC with TEIN basics and Konig Unknown *PICZ*

I don't understand why you all would like a spoiler on yours... They're FWD! It does nothing for the front...get splitters.

[Touge_tC]

The spoiler is all for the look pretty much. That's why it's not very important, but kind of a side note.

[SilverKnight]

Good point...

[chicotunner07]

Yeah all looks, and it does no harm either so why not!

Guess you don't know about aerodynamics and downforce. It is not about which wheels drive but about keeping maxium contact with the pavement. When a vehicle is moving fast enough, based on it's own aerodynamics, the air flowing undeneath the vehicle compresses causing a high pressure point. With the shape of current cars resembling the aerodynamic chord of a wing, a low pressure area is created above the vehicle. Thi is called - Lift. Quoted, "Finally Bernoulli’s law is applied to the different flow velocities at the upper and lower side of the wing resulting in a lower pressure at the upper surface and a higher pressure at the lower surface. These pressure differences produce a force on the airfoil - the lift."

When the rear of a car begins to lift, it unloads the suspension. In hard cornering, this is a bad thing. An unloaded suspension no longer has the correct geometry to maintain enough pressure of the tires to the pavement. You want the suspension loaded, to a certain degree, to squat the tires firmly against the pavement. Stiffer spring rates allow you to preload the suspension with more download. More download equates to more G's in the corners. With this being said, lift of any type, on a vehicle is not wanted;RWD,FWD, or AWD.

Here is another conversation that makes some valid points, but still misses the mark. http://forums.streetfire.net/archive...2681.htmlStart from the bottom and work your way up.

While this is true.. you do a very good job at proving all of your points. I like that! Thank you very much. But, the type of wing I was looking at really wouldn't create all that much downforce. I mean, it wouldn't hurt... but it wouldn't really stick me to the pavement either. Plus, this car is more show than a performance car. I would still prefer to drive touge in the Miata over the tC.

So true and a good point. Majority of spoilers out there are for show and only create drag. I chose the Kaminari wing because it is actually an inverted wing. It creates lift (downforce) that is opposite that of an aircraft wing. It is also adjustable (manually) so that I can create more downforce or less drag. You can feel a difference.

Also, look at different autosports. You will notice that the rear spoilers are different type from dirt track, to Nascar, to NHRA. It is all based on aerodynamics and what you are needing to do.

very interesting indeed!! yeah goin 100+ makes the car feel "floaty" and "mushy" i really feel some downforce would really help sabilize at those speeds!!

[navylife59]

In a straight you won't need much more than an extended lip like they use at Nascar. Actually, I was suprised at how stable the tC is at 128mph.

[tanklugz]

hey, not bad, not bad at all

[monkeyzz510]

Hey when you bought the S/C did it came with everything you need?
just asking because i don't want to spend more due to my poorness

[navylife59]

Everything except for the install.

[MkhoiD]

i need a trd supercharged badge...anyone is selling it?

[navylife59]

Try TRD Sparks or EBAY

Yup .. i've seen a few on Ebay .. dunno if it's still there tho

[monkeyzz510]

after gettin the S/C installed do u have to do any tuning for your car?

[navylife59]

No. The Dealer reflashes the ECM w/ a TRD map; a lil benign, but very reliable.
