OK.....Take a look at what Porsche do with the Carrera cup cars, its basically a maturation (more extreme) version of the GT3 air deflector.

Wouldnt take much to make some bigger suspension mounted air deflectors, sadly the current regs dont allow it.
The correct fixing of the front bumper and under tray is absolutely crucial to air flow as Rick will tell you after his brake failure at Croft.

Told you its out there and easy to find after 10 min on google!

Here's a photo of the massive, two-part GT2 duct in place:

These wouldn't last five minutes on a race Boxster - its too low. This rennlist thread says this one is also used on the 996 GT3 Cup but I'm not sure I believe that.

Here's a nice comparison between the standard ducts, the 997 GT3 and the 997 Cup ones. Note the cable tie hole on the largest one.

You can get these from Porsche Reading (on our discount) for not very much - in fact they're so cheap you might as well keep spares.

Rear ducts are also available for the GT3 and Turbo but I have no idea if they would fit on a Boxster.

This is what Steve is on about. 911 996/7 CUP cooling.

Need air flow through the inner wheel arch and a barge board to deflect onto the brakes.

Part numbers:
996-575-232-30
996-575-231-30

But £130 each so a DIY might be a better option, any old inner wings or bumpers lying around!

Chris

Can we clarify if the GT2 part is permitted? As mentioned last time I asked it was not, and in fact the GT3 deflector is a bit of an 'interpretation' of the rules.

As far as I can tell the inner wheel arch mod is ok as we are not changing the front bumper aperatures.

From the 2014 regulations:

5.11.5 Deforming or removal of brake backing plates is permitted. Additional brake cooling may be fitted provided no bodywork has to be removed or modified.

That says to me that you can fit any Porsche or non-Porsche cooling. Bodywork is also defined in the regs:

5.6.1 Modifications Prohibited
Other than those modifications permitted above, all bodywork must be as produced by the manufacturer
in all respects as to material, thickness & contour. For the avoidance of doubt, this includes the wings, doors, bonnet, boot-lid, and all other body panels.

The opening or use of additional apertures other than modifications permitted above or the taping of normal bodywork gaps, spoilers or any profiles is prohibited.


I really don't think anything you put underneath or in the wheel arches can be described as "bodywork". That last phrase though could rule out modifying or removing the wheel arch liners - which I know some drivers have already done.

You need to verify ideas with Nick and possibly also with the BRSCC - I'm just the media representative, remember!

Was looking at Guillaume's 997 Cup this morning and it has special wheel arch liners together with the scoop as shown in Garry's photo above. Personally I wouldn't simply cut a big chunk out of the existing wheel arch liners without some form of grille protection for the rads.
