sick F****** Z with balling *** parts!!

 

It's the factory rear bumper with the Voltex diffuser and trim piece. I did cut the holes out myself and they are covered in carbon trim pieces from LighterFaster.com.

 

Pardon me Sir.... Would you like some wine with your swiss cheese? Hehe just j/k, I like the front bumper. 8)

 

I'd consider putting some mesh in the rear cutouts and have both the mesh and covers painted blue to match the car or the rims. That way it tones down the rear a little, but keeps the functionality.

 

Or be original and wrap a dream catcher crystal in the middle of the holes. Possibly a wind chime would also give that peacfull feeling as you drive.

 

+1 but I like the cf/black against the blue. .02 out.

 

^^The mesh isn't a bad idea, I'll have to see if I can find some in the garage or attic and see what it looks like. I like the carbon fiber though, it pulls it all together.

 

SBC on the way from across the pond. Been waiting over two months already.

 

this car is really ahead of the game. in pensacola nonetheless. i thought the panhandle was devoid of anyone capable of piecing together such a z. proven wrong.

i have been jealous of the endless setup for a while now.

ya gotta see the r35 bbk. like whoa.

 

There's actually a few nicely put together vehicles up here...just a few. Thanks for the compliment.

 

The whole idea behind painting the handles to color match was to make them not stand out as much. Never really liked how they all clash with the body color.

 

I'd really like to put the Voltex front on, but it seems even longer than the Chargespeed front. I'm afraid I'll have more issues getting into driveways not to mention speed bumps and bad roads. I'm sure it'll happen soon though. I'm not big on miss-matching pieces. It does flow pretty good together, IMO.

 

I"m skeptical of the diffuser, heres why

You have a definite amount of air in the space in front of the rear bumper. There is no outlet for this air to currently escape. So there is no option but for this air to circulate within its given boundary, with the outside air sliding along the boundary containing the air. The only resistance you have is the air on air at the boundary opening.

So if you create an outlet for the air to escape, you've now created a flow path through the bumper. Now you have air resistance along the entire inside of the bumper.

air/air resistance < air/bumper resistance. see hastily drawn figure 1.




The only way I can see this being beneficial is from the overall aerodynamics of the car and the turbulent low pressure zone behind the car. This may be an effective way of increasing the pressure in that area and lowering the turbulence thereby making you more streamlined. I'm not even sure it would work in this way though.

see hastily drawn figure 2



So if the benefit of the increased pressure offsets the disadvantage of the increased drag, then I would think that you are good.


*note: all explanations are from someone who has a basic knowledge of diffusion from 5 years ago. Do not take these explanations as scientific fact since I'm probably wrong

 

Found it:

People buy after market auto parts for various reasons. It may be because of a broken or worn out part and an after market part is cheaper than buying a new factory part from the dealer. Sometimes people purchase parts in order to enhance how their car looks. Many parts are purchased to increase the power of a car. A rear bumper diffuser may be purchased for both looks and performance at the same time.

I'm sure you have seen a bumper diffuser on a car, but you might not have recognized what you were looking at. A these products can come in various sizes and styles. It depends on the car make and what you are trying to accomplish.

As a vehicle moves through the air, there is a corresponding air flow over the entire car, both over the top as well as underneath. One critical area is the flow under the car. The air flow under the car probably is faster, which will produce a phenomena called down force. Down force tends hold the car to the road and improve hi-speed stability and cornering. It is a good thing, and the faster you go, the more you want. It is almost always built in on race cars and now it is showing up on more and more street cars.

One method of increasing down force is a rear bumper diffuser. Here is how one of these works. A problem can occur when a high-velocity air stream from under the body meets the much slower airflow of the ambient atmosphere coming over the car and behind the car. This collision of airstreams causes turbulence which can be dangerous. The rear bumper diffuser is designed to provide an area so that when the air between the car's airflow and the external airflow come together a boundary is formed and this area is then less turbulent.

This is the key idea to keep in mind when considering purchasing one. Your car may have been designed like some BMW's, Ferrari, Mercedes or other cars with a very high top end. On a typical street car the bumper diffuser does very little until high speed are obtained. As mentioned before, many high end cars such as Ferrari, BMW, Corvette, are now coming with a stock rear diffuser. Some have extensions under the bumper which can accomplish the same goal. A well designed system can both look good and offer you better high speed stability for your car..

In general, all after market diffusers are either a replacement bumper with a built in diffuser section or a part that must be attached to the car which serves the same function. Generally you must cut one or more holes in your bumper before the diffuser part will fit and be effective. If your need for high speed stability or a more unique look is worth a little installation time, then a this may be your answer to more stability and unique looks. However before you purchase this product, completely check out the installation instructions and the pictures of different looking applications using it. You may want a bumper diffuser just for performance or perhaps because it also looks good. If you want both, then this is a product for you.



Seems it only benifits at very high speeds to add down force but is primarly never fully benifical in street cars. Better for consistant high speeds in race cars.

 

Wow. Brrcats- thanks for the awesome visuals- I mean that, they're awesome. And robbinsj- that's a good write up on diffusers. Both are very informative and I appreciate the input.
By the way- I have had serious issues coming into turn-1 at high speeds where I do open lap days (spun way out into the field at 120)...maybe this will help?
Thanks again for the input!

 

The body kit is too aggressive for my personal taste, but it is obvious that you have put a lot of work into the car. I love the wheels and brakes.

 

hmmmm. I think i found where and how to install my diff and trans cooler.

Love the car by the way!

 

nice

 

Yea it could help at 120mph, post up if you notice any differance in the Butt-o-meter.

 

My favorite DB Z to date. Gratz on the look with all that hard work.

I agree that a dark mesh in the holes would clean it up/finish it off. Maybe smoke the blinker? And please, a new antenna you cheap bastard! LOL

Nice job.
