very interested in these things..

Damn, there I was thinking how clever am I thinking no one will pick diffuser and there you are only a couple of posts down!
+1 for me then.


I was also thinking about the lack of real rear wings available for us. The best of the bunch is the 968 with adj centerpiece. It got me thinking when I look at all the ones for GT3s etc why can't we have something that will develop some real downforce. The mounting points have always been the main issue for us. Very few guys are running with Lexan but even those guys have to construct those 'Power cable' towers to mount their big wings. How about being able to take out the centerpiece from the 968 one and have the mounting points for a big ***** on the back there? You could offer it as an option for the guys buying the 968 one? I'm only thinking out loud, but it doesn't seem too hard to me. I think you're going to need something to compensate for the race splitter anyway???

Some great ideas in this thread!!!

Lorax

How would you guys make an effective diffuser with the stock exhaust placement?

Who needs to worry about the stock location???

333pg333

Seriously, it would also involve getting rid of the spare tire wheel well also. I would like to see if some sort of underbody panels couldn't be fitted to help out with turbulence as well. Guess I'll leave that to Chris.

Lorax

Well, the reason I'm mentioning this is because I am building this myself as we speak. I have no exhaust back there and my tire well is trimmed. It's doable, but as a marketable upgrade it's just too much work for most people.

Yep, it's definitely more than just a bolt on part. I would think that you'd still need to do something about the undercar turbulence too though, wouldn't you?

Lorax

Too get the most out of it, definitely.

The stock pans are fine in the front, but starting from the passenger compartment you should begin forming channels.

The way I am doing this is by essentially creating 3 sections that bolt on seperately. The center channel is one long piece (Buit on an aluminum frame) from the starter back that has about a 7deg rake starting from the torsion bar housing. It's about 36 inches wide IIRC. The width was chosen because of the obvious space created between the edges of the two floor pans, where the two factory body trays bolt up (those will be removed, obviously)

There will also be two smooth pans theat cover both of the sides.

Mounting is easily accomplished. Steel beams in a "T" shape will run the chassis lengthwise. Those will be permanently attached, and both the side pans and center channel will attach to those rails. The downward protrusion of the rails will ultimately form the channels leading up to the venturi in the rear, as well as allow for easy installation/removal of both the side pans and the center channel independantly.

7 deg should be just about the perfect rake for our application, which is lucky because that is about as much as can be allowed. It would be better if the rake could start further up the body, but it wouldn't clear the trans if it did. It is possible to make a small cut out so that the trans could protrude slightly, but I decided the negative effects of that would outweigh the benefit of beginning the rake earlier. Keeping the air "Attached" to the underside of the car is essential if you actually want to create downforce. On that note, since this is such a wide channel, a fin will run down the center of the raked portion to combat turbulence and help the air "Stick" better.

So yes, if you actually want to do more than just reduce turbulence a bit, then underbody smoothing and channeling are essential. If you do it right you can create lots of downforce.

How about RUF, Kremer or Strosek equivalents?
Much better than the Cup units IMO.

+1 Including a partial delete of spare tire compartment. If I ever return to 951's, like racing, I'd need one.

pete95zhn

935 style, YES!

Duke

+1 this is by far the most interesting thing mentioned in this thread!

I would say skip the 968 wing. D9 is already working on some very high quality stuff and IMHO it would be a waste for CPR to compete when there's so many other interesting things missing on the market.

Here's my top list:

RS style interior door covers
Small mirrors
A nice looking rear wing that makes a lot of downforce, nothing less than a 997 GT3 RS type will do IMHO
More modern looking tail lights
A huge hood vent similar to HansB's solution from an Oreca Viper
And how about a Torque tube/bell housing that would offer a tranny conversion!

333pg333

^^ You kooky Swedes. Just love your converted Trannies. lol

Well you cover my point Duke. But creating decent mounting points for a proper rear spoiler isn't easy without a decklid that they have. That's why I think by using the 968 mounts we can achieve exactly this. I agree that if D9 are doing a 968 spoiler then leave that to them. I'm sure there's enough room for both these companies to exist without treading on each other's toes.

Duke

But while we are simply dreaming about trannies you open minded aussies are taking it to the next level!!

333pg333

...not that there's anything wrong wth that lol...

Hey you smart guys should figure out a way that we can mount a wing that will create proper downforce.
Has anyone ever determined just how effective the 968rs one is? I just keep seeing those 2 solid outer parts of the wing mount and think how we could do a double decker or some big stepped thing that would really do some damage!!!
