Hey guys. I am looking into diffuser options for my rear bumper piece and don't have the science background to understand what type is really best for performance and not just looks. I have seen a huge amount of different looks and styles and at this point am not sure what would be the best performance and looks combination. Any input, including pictures as examples, would be great. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Nice. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> That is the general style I was thinking of going with, just wasn't sure if that is the best kind or what the differences are in say that style and the dynamic trim piece with the cutouts...

Those are just for looks. The C70 one is actually remotely functional. I dont think performance should be a huge deciding factor, though it is always good to recognize performance in a design.

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (sanatarium)

Yeah, I realize our cars don't really have that much of a performance factor where a diffuser will really matter, unless some major upgrading, i.e., ATP turbo kit, etc. has been done. I just wanted to make it a stylish yet performance-minded one. I got some SWEET new exhaust tips that I know for a fact no one has ever put on a Volvo that I think will look awesome with the diffuser I have in mind. I will unveil them at the same time as I unveil my new color scheme for my car. I just wanted input from more knowledgeable people on what was the best style that actually might help performance or gas mileage. I love the summer when the time is available to do cool stuff. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/smile.gif" BORDER="0">

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (PasS40ion)

Yeah, I am thinking of taking one class through independent study, but as it stands I don't have any classes until August. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> Freedom. Just work to pay for future school expenses, girlfriend, and car. In that order, lol.

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (sanatarium)

LOL. I knew someone would rearrange that...Gotta keep the woman happy otherwise my summer won't be so fun, <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> I am including her on a few of the projects. If she feels included things go MUCH better. And including a woman when it includes custom upholstery is never a bad thing...

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (sanatarium)

So what do you guys think would be the best material to make one out of? Fiberglass, CF, aluminum? My brother said it wouldn't be too hard to make an aluminum one similar to this one:<br> <IMG SRC="http://i20.ebayimg.com/04/i/001/44/c6/cdf5_1.JPG" BORDER="0"> <p>That one is nice but they want $300+ shipping for it...

These are more for performance. CF or FG would look better though, especially if painted

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (sanatarium)

Maybe I'll make an aluminum one and use it as the mold for the layup of a CF or fiberglass one. Super easy to make something when the mold is done, lol.

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (carreragt7)

all i know is that you better have a front lip with the cf insert and a rear with the cf defuser and maybe some side skirt on my car before that meet up. <br>an idea <br><IMG SRC="http://i35.photobucket.com/albums/d182/kpsingh/dsc05788mh0.jpg" BORDER="0"> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: Best type of rear diffuser for our cars, or in general. Brainstorming ... (kpsingh0)

I posted this in the C30 lip process thread too, but it really fits here better so I here it is. Whaddya guys think?<br>And for kicks and giggles here is my spy photoshop of my rear idea adding a diffuser and custom made exhaust tips. Please note this is just one of many ideas and the possibility of my rear piece ending up like this is...actually pretty darn good <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"><br> <IMG SRC="http://photos-h.ak.fbcdn.net/hphotos-ak-snc1/hs009.snc1/2875_75382444441_775614441_1689623_7516841_n.jpg" BORDER="0">

It looks good. I like the integrated exhaust. But it will be hard to make that work. Our muffler is too wide, and to integrate those tips, you are going to have to curve the tailpipes in and then out again I think.<p>I could be wrong of course. I would definitely suggest you check before you get too far into things though.<p>

Re: (mofolicious)

I have the Heico exhaust, and I have the exhaust tips still from my MS Design kit which does exactly what you says might need to be done: they have a curvy loop to allow them to be closer to the middle. The exhaust will be super easy, I've been researching this project forever during classes, work, and watching tv. I'm a multitasker, what can I say. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/wink.gif" BORDER="0"> I will be getting my exhaust tips that are similar to the photoshop mockup in the next week or so. I am just waiting on them to be able to take all of my stuff to the powder coaters. I might have the exhaust ceramic coated instead...they said the turn around should be 3-5 business days. So I should have all of my trim and my iForged all nice and purdy within 2 weeks. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0"> <br>The hardest part will be getting a diffuser that I like or making one. There are a few options I have seen that I like, and I am researching them. If anyone knows of any relatively inexpensive diffusers that would work in this sort of setup let me know.<p>What is great about the exhaust tips is they will line up with the current curve of the bumper, as shown in this pic:<br> <IMG SRC="http://photos-a.ak.fbcdn.net/hphotos-ak-snc1/hs009.snc1/2875_75382449441_775614441_1689624_3134021_n.jpg" BORDER="0">
