Hey Cheston...I should have known the Aug timeframe you gave me earlier was too good to be true...LOL...I'm still interested though, but now only in the rear diffuser. Can't wait to see it...Thanks for making things happen for the Z...

John, the reason why the TS style diffusers are more expensive is because they reach way underneath the car, they replace the factory plastic cover. That's how large of a piece it is. Thus justifying the cost.

yea. the front diffuser is not just a lip addon lke the Cwest is, which in theory is actually a front splitter, this is a full diffuser, which channels air flow underneath the car, its size is relatively the side of your hood, just, underneath the car... hence the cost, which is, relatively cheap for the materials and compeition's pricing..

Yeah, I think I agree with most people on the rear diffuser. Alot of people have aftermarket exhaust, and this causes a huge hole in the rear of the car. Will this rear diffuser cover all exhaust systems, meaning stock and aftermarket??? And what kind of functional numbers will you provide(if available)???

since i dont have a windtunnel for a car readily available *who does? ;P * i can only estimate the amount of drag and/or lift coeficient reductions based on the angles of the diffusers...
the rear is going to be hard to make everyone happy, simple put that there are so many exhausts, not everyone will be able to use what i eventually put out... but yea.. the single canister and or dual canister designes leave ample room up behind the rear bumper for some cool diffuser designs.....
the main goal of a rear diffuser is to smoothe the air flow out and angled up and away from the ground.. a simple 4 degrees of incline of a flat surface (such as the surface of the rear stock muffler) can decrease rear lift by .1-.2 based on speed and location relative to the rear axles...

Almost as if you are saying stay stock or go with a canister design for aerodynamic purposes with your diffuser. 
I do know one thing, Nissan has a wind tunnel, and they did test the stock exhaust. Hopefully some of the aftermarket manufactors took that into consideration also.
You would open your market up more, with the rear diffuser being able to fit more vehicles, of course.

umm..please make it so it can fit the angled tip injens...please 
i have a question though...assuming the rear diffuser you made was very close to the exhaust tips...would the heat ruin the CF?

depends on the resin mixture that is used.. the CF isnt going to be wrapped around the exhaust, just near it. there should be enough air flow to cool around the exhausts if i can get the diffuser correctly set... besides typically the rear diffusers are supposed to be functional.. i dont think you're gonna stick your head underneath to look at it all the time.. it will probably be dirty from the road scum.
i want the front def, and would love a rear one , but

The purpose of a rear diffuser is to let the compressed, fast-moving air from underneath the car slow and expand before it leaves the underside, creating a low-pressure area. This low-pressure area effectively "pulls" the rear of the car down (in laymen's terms) reducing lift, or, if there is no lift, increasing downforce. For an obvious example look at the rear of an F1 car.
A truly functional rear diffuser is a great thing at high speeds. Keep things balanced F/R with a good front splitter though.
Plus, there's the fact that it looks bitchin'!!!
