Hey all,
I did dig up some of the under carriage covers that have been brought up lately, these are brand new and coming in from Germany. As of right now they should be about $230 plus shipping the price might come down a bit depending upon how many we order. Does anyone have any interest? Thanks here is the article on the cs resto from BMW which has one of these installed.

The purists buying belly pans

Before installing your new belly pan--treat its inner surface with POR-15 if new parts are still being made from pressed paper--this will prevent future absorption of coolant or oil and resultant damage--without detracting from its external appearance--

And--if still of pressed paper--will go a long ways toward re-inforcing the attachment points at corners thus extending the parts useful life.
 
Other than originality, does this belly protector do anything beneficial?

I like to drive my coupe and do not show ut too often...

Belly pan--purpose served

Perhaps:

It may serve to minimize front end lift by "smoothing' underbody air flow and reducing drag from front end underbody pressure and turbulence.

Test of before and after at maximum speed attained and degree of front end lift felt or experienced might reveal whether it really does make a difference. Big stretch--it could also contribute to the "greening" of our Coupes by improving overall fuel economy.

Who will volunteer to run at full throttle with and without a belly pan in place--Peder?
 
The belly pan on my P 928 is steel and some of the benefits are: block road obstacles from tearing off the Alt, AC, PS pump; or knocking a hole in the alu oil pan; or shredding a hose. It does help keep the engine temp down slightly as well as helps cool the Alt (though stock the Alt has a cover with a hose that runs forward of the radiator).

The shred-board that was under my e9's engine lost it's life in Deutschland by the PO. Not sure it could block and tackle like a metal type...

I almost had a horrible result observing a drive shaft in my lane on I80 westbound past Davis while running the e9. The car in front didn't see it hit it...flying through the air at me...I decel and slide right...it arcs down hitting my front left trim inches off center leaving a small dent and no marks on the belt trim, as it splits apart half the shaft hits below the left lights leaving a small elliptical dent, the other half spins up missing the windshield and just leaves a golf-ball size indentation next to the sunroof. No creases on any of the hits and didn't take out the glass or me...our coupes sure can handle the road. The two part shaft could have made a mess of things if it went under the car with a shred-board pan!

There have been some test I read on a 928 board a while back showing modest improvements for aerodynamics. Most of those guys that use it drop the pumps to lighten the load some have gone to alu skid plate/belly pan.

I have bought a few from W&N. Perfect fit. Screws and body nuts included.
Makes a nice addition.
Cannot be used with the Lokari inner fender protection in alu with rubber seals.

Besides the aero-dynamic function described above and the protection from dirt coming on the engine and the components from underneath, the cover also takes care of the holes in the front valance.

It's some sort of painted pressed paper / carton-ish like material, much like the interior panels. Easy to bend and brake. Definitely not a good choice of material for underneath a car. Will need some additional coating to make it last longer. But it's going to look good on the car.

"Shredboard"

I suppose it could be covered with a couple of layers of fiber and epoxy type bonding then painted...sort of like hull repair??

Nix to POR-15

I think POR-15 is nice stuff, but too brittle to be used on belly pans, it would crack and that would be that.

Rather use a flexible material. I have a five gallon can of urethane deck coating stuff that ought to be just the trick. For sufficient reimbursement I'll ship anywhere, but you can get the stuff, or something like it, from hardware stores, roofing supply houses, and so on. I'll not hold my breath that anyone will take it. BTW it can be had in colors too.
 
several years ago I distibuted POR-15

I no longer handle the product but I'm a believer in its many practical uses.
Unlike Tony's statement I didn't find that POR-15 was a brittle product in many types of applications--actually I found it to be flexible and strong.

For example--on the backside of door panels where application actually strengthens them and will permanently prevent future moisture absorbtion--door panel backs--same pressed paper material that the under pan is fabricated. I have done this treatment to both my 2002 recently and to BLUMAX 19 years ago--never a problem and both cars still have original panels still in fine condition--BTW--big help in preventing the clips from tearing out.

Two coats of gray POR-15 applied to the inner side would add virtually nil in weight but would have the effect of strengthening the pressed paper under pan--will re-inforce the part, prevent absorbing any oil or coolant that will inevitably present itself--and will prolong its useful life due its enhancing of its structural strength. When I decide to fit BLUMAX with a new under pan it will be coated--as noted.
 
not available anymore?

I tried to order another one of these and was told that they are nla again. anyone have another?
