Re: Gauging Interest on Gen 2 Rear Diffusor Blades

Clicked on the pic link to photobucket and it was a some drunk chick at a party of yours? Was that your gf? Is that the right link?



JUST KIDDING they look great. BUT, I don't like the spacing. When I did mine I took a rear shot of a Gen 3 or 4 (can't remember) and sucked it into my CAD program and reverse engineered the spacing. Came up with:

I (x) I (2x) I (x) I

I of course being the blades in that example and I think x = 9"

The side shot looks great - **** curb appeal and maybe the rear view spacing will look different when coated.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

Good observation on the spacing. The blades are bent different way so that they can be spaced further apart or closer together, roughly 1 or 2 inches spaced. If you look at the left blades and right blades their inner mounting tabs are bent out and the outer mounting tabs are bent in. They can be swapped around in a couple different ways to get a better desired distance, or the rear mounting tab can be extended with an oval hole to make them adjustable. All simple things :)

To match a newer Vipers spacing is damn hard because of the hard mount bolts. The inner most bolts are hard to line a diffuser up perfect on them, we tried. I am happy with the spacing and most likely either 4 or 6 will be placed on my car in that fashion. Most likely I will go with 4.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

i think with three on each side the spacing will look a little more proportional, the color may change the look as well, still a great idea and a great bolt on project :2tu:

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

Since I am a walking picture store here's a good illustration of how I was able to move my inner pair inboard to get the spacing I wanted. Mine also took no additional holes to the underside but you can see the factory bumper cover holes several inches off to the outside. Plate versus no plate I guess.

Those things painted yet? What the hell are you waiting on???

I think they are going to require powder coating being that they will be right behind the wheels. I leave for Rhode Island next Thursday and the powder coating won't be done by then.

(I might mock up a set of Satin Black ones though)

You utilized the hard mount bolts, easy to do without the rear exhaust. The rear exhaust tends to bend the rear bumper down slightly and create an uneven section in the urethane.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

The SRT difuser fins are attached to a CF "panel". This makes it a lot easier to attach the blades. I added an extra blade on the outside of my SRTs'.




The back and bottom panel of the GTS is completely different. It is somewhat difficult to secure the blades to the rear panel. I cut holes in the panel in order to use the existing tabs on the blades...





KINGSNAKES design would be a simpler install.

Not to mention the SRT blades are around $50 each....:omg:


KINGSNAKE... Feel free to use any of the info or photos I sent you...

Looks Good...:2tu:

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

Thanks Treesnake, your pictures you sent me were an awesome starting point.

I can tell you 50 dollars a piece is not even close to my price so it has produced significant savings for a mod that looks great. Minimal R&D has been put in this so the initial buy in was pretty low. Now that the blades have been saved in the cutting program they are easy to produce and make small changes if necessary.

The mounting difference between yours and my setup would be roughly 1/4 inch or less further back on mine since I use the stock holes. It would not even be noticeable.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

I like them too, I'm in..
Any idea on a price?

I would probably use six of them, since I have side exhaust...

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

The economics of DIY is pretty sweet here. Off the top of my head the 24 x 48 x 0.080 sheet I bought was $30 to $40 and would make like 4 to 6 sets of four blades. That's like $2 to $3 per blade.

On a related note as many have mentioned going to 6 blades... Why? More is better? I think the effect, especially those that are just doing the blades and not the more functional plate/diffuser, that effect is done at 4 blades. That curb appeal effect.

Not quite the economics I am working with. I am physically unable to cut a straight line by hand lol. These blades are done through a professional fabricator and everything from the edges to the holes are laser cut for precision. Each blade is identical to the one next to it. 2 to 3 dollars per blade is a lot cheaper then I can get them for. If I was actually making them myself sure but I have to pay the piper which I don't mind because it allows me to offer them much cheaper then any other SRT blade sells for and they are tailored for the Gen 2 which is currently unavailable from others.

I agree with the 4 blades, 4 is enough for me. That is why the pieces of flat stock I currently have are 8 inches. I would need 12 inch flat stock to put in the bumper as backing for 6 blades.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

Maybe you're right Dave, I'll probably just go back down to four, don't want the rear to look too busy/ ricey :)

And you can always add 2 more later. I can snap a few pics today with 3 per side.

If the first 2 sets sell today I am going to have 50 blades made next week so if anyone is interested shoot me a pm. Pricing would be good.

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

FWIW, I haven't seen a functional rear splitter on a Gen 2 that looks sharp. When they're set up to work correctly, they're too big and they don't follow the body lines well, curvy car, straight metal = design school no-no.

For looks, SRT-like short and angled seem best but when deciding, make sure you know what the priority is, looks or air management....hard to have both on a Gen 2!

Looks great for a track car. Being that I don't track my car nothing even remotely that size will be put on my car. It detracts from the overall look of the rear.

Thread hijack in process.......

Dave, what tires are those? Are they Hoosier 100s or something rare and custom order?


Now we return to our regularly-scheduled discussion.......

Well said sir. Honestly most people don't track their Vipers and these blades just add an extra oomph to the rear. Like I said, after seeing Treesnake's car a while ago I started looking into them. They look really sharp on the rear of the gen 2. Here are a couple ground photos of his finished product. His car looks phenomenal and this just makes achieving that look easier.

Now maybe in your opinion (which you ARE entitled to :D) you don't think mine looks sharp, but I did build it to follow the body contour. Ref. the pic I used earlier. And short of some wind tunnel testing which will never happen, based on the near clean rear bumper cover I'm saying air management is "good."

All the above is why I build my own, just like he is building his own blades. To get the result and look that we individually want.

I could have done the plate in red to match the body and maybe even the blades red too, but it is quite common on performance cars to have the aero ground effects components in black. So then are mine. but they do fit the roundness of the body ;)

Re: Gauging Interest on Gen 2 Rear Diffusor Blades

They are R-100s. Subsequent to this first track outing at TWS, we convinced Hoosier to begin producing the R-100 in a 355/650-18 as the tire in the photo was too big in diameter and we could not get the car low enough. We had a dramatic improvement in lap times - over 2 seconds a lap on our local 1.7 mile track, the Motorsport Ranch in Cresson, TX (not far from Dave6666).

I need to come out there and see your car. It was still under construction last I looked. It does look sweet.
