Hi guys,
can someone please provide me with the part number to open the lower gills in order to vent the brake by having actual working air ducts.
Thank you kindly.

 

T2R15213 and T2R15214. They are recommended for use on the CC brakes at the track, but no mention for the steelies. It is also advised that the ducts only be used on the track, and be removed for the road. Thanks to Dave (DJS) for storing this track guide:https://redirect.viglink.com/?format...1.pdf%3Fdl%3D0

 

As I recall, someone tried to procur a pair, and wasn't able to find them.

 

U.S. suppliers have discontinued the distribution of these parts. You can get them in the UK for £678 ($870) each side. Spend your money on a pulley and a tune.


Edit: I also found a US supplier asking $1700 each side.


I suspect they were discontinued because of a design flaw, or folks were abusing the use by not removing them after track use.

 

Does anyone have any pics of them?

 

Not worth it for that amount of coin.

 

google the part numbers and you'll find drawings of them.

 

It might be possible to simply remove the black plastic behind the dummy vents, I did this on the LHS of my old XFR, it was a single piece of moulded plastic.
Would cost nothing other than the labour of dropping and refitting the front clip.
If it could be done then it should improve the airflow to the brakes (but not to the engine intakes, as they sit way up high behind the grill).

 

By doing that, I would be concerned that the unrestricted airflow through those 2 openings would significantly reduce the airflow through the heat exchangers. Properly designed ducts would maintain sufficient back pressure to ensure that wouldn't happen.
