NEXT EVENTS ARE MARCH 27-29, AND OCT 17-18 2009.
We're heading out with our customer Tom. He has a blue 350 with a Greddy TT kit. As a matter of fact I need to get the car in here shortly and start finishing the prep for it.

isnt the TS diffuser made to go with the widebody G? I remember someone putting it on their G back in 05 and it took a hell of a lot of work (this was making it fit to a Kenstyle Rear)
Eric, do you mean using a balsa wood core sandwidched between carbon fiber (e.g., a la Corvette)? Just not sure from your response. Please let us know what you mean. Keep in mind we want to add a minimal amount of weight to the cars, but I don't mind adding 3 or 4 extra lbs. if it will save us 30% in fabrication costs.
another alternative (I gotta check the under body of a G again).. those with the GTSPEC or TANABE under body brace knows that it becomes a scratch post.. having an additional 1" below the exhaust wouldnt be too daily friendly since a lot of the G Z guys (including myself sometimes) scrape the mid pipe =\ or cats.. you can partially cover the bottom similar to the picture of the GTR underbody.. would making panels to cover the left and right side with a rear diffuser achieve the same results?

If you just do a regular sheet of carbon with no curvature its very weak in structure... you'll need a lot of rivets or mounting points to keep the thing from flapping around or flying off when driving at close to 200mph (i would assume) seeing how the "exotics" under panels all have some kinda core I'd assume they have this for a reason...

At this point we do not know whether a partial cover of the underbody will be sufficient...
Perhaps we can use a complete underpanel in the middle of the car and put an aluminum plate over the area that usually scrapes??? I don't know, but I am throwing that out for discussion purposes.
To me, the most important considerations are the front undertray/diffuser and the rear diffuser. In the worst case scenario we can use an aluminum plate in the middle section of the cars, though we do want to keep the weight minimal.

Thanks, would we be able to just eye it from pictures? it doesnt need to be exact.. diffusers with the same general design should all function the same no? wouldnt a cheaper alternative be something like the mastergrade rear TS diffuser.. granted that was a copy of the Z diffuser modfied to put on to a G.. we can probably purchase 2-3 of their diffuser versus one TS diffuser..
isnt the TS diffuser made to go with the widebody G? I remember someone putting it on their G back in 05 and it took a hell of a lot of work (this was making it fit to a Kenstyle Rear)

Based on XKR's experiences, we will probably eliminate the GTSPEC chassis brace.
At this point we do not know whether a partial cover of the underbody will be sufficient...
Perhaps we can use a complete underpanel in the middle of the car and put an aluminum plate over the area that usually scrapes??? I don't know, but I am throwing that out for discussion purposes.

TTg35fort, since you are already talking to the guys at Bulletproof you might ask them about the rear diffuser from First Molding. I know it for the Z but you guys seem to have the know how to make things work.

hmm I can do it actually I've thought about doing it for a long time with my car.
Problem:
1. Adding 1" to the whole bottom of the car.. ehh guys that scrape now will eat complete ****.. while the carbon will take a beating you're more worried about the mounting points and brackets
2. Rear bumper Kenstyle Rear, Chargespeed Rear, OEM Rear, IMpul Rear, Veilside Lip, while I have access to ALL these kits (obviously) theres too big of an extreme between something like the Chargespeed Rear and the OEM, a design similar to TS might get us around this problem but at the end of the day this is going to be one low diffuser
3. Method of mounting, while you can make the carbon millimeters thin the carbon, once again, will loose its structural strength without a curvature.. this will require more rivets or bolts/mounting points. It'll also make it pretty costly if you ever hit the middle of the car over a speed bump or something
But I dont think we're going to need to cover the ENTIRE bottom of the G I think partially covering certain areas will result almost the same as covering the entire underbody. IMO we would only need to do the two sides and we can leave the area where the driveshaft runs (along with the mid pipe) exposed... and maybe even be able to leave the trans area. Trans will need to be cooled and servicing the trans is going to be PITA if you have to drop that panel everytime.. The CATs are also there (common scrapping spot)... if the front under tray, again problem with the many different style of bumpers and lips, was designed well with a removable splitter working with a diffuser that starts axle back (now the spring cups will get in the way) should do the trick.

Klumzyee, you make some good points. Leaving the center section open allows for better exhaust, transmission, and rear differential cooling. That air flowing through that center section could be accomodated in the design of the rear diffuser, the way it does in the GTR. I hope you come up with something for the masses. I would rather have something in ABS plastic than either carbon fiber or aluminum, so that if (when) it starts getting worse for wear, it's not such a big deal to just replace it.

How about sandwiching a balsa wood core between two layers of carbon fiber? Of course, the ends would have to be sealed to keep the balsa from getting water logged.
Assuming we go with Carbon Fiber, I will be attaching an aluminum skid plate in the area where my car is prone to scraping.
