Fits 2014-16 GT3/GT3 RS models
Purchase Rear Lower Diffuser
  • Rear Lower Diffuser SKU: SKUGT3DIFF

    ★★★★★ ★★★★★ 5/5 Stars. (2 Reviews)
  • MSRP $1,053.15 $795.00


Redeveloped engine underbody paneling with an increased surface area compared to the 911 GT3, as well as four additional fins.

Made of stamped aluminum and shaped so that it rises toward the rear. It thus fulfills the function of a diffuser and ensures downforce. The four plastic fins channel the airflow under the rear, further accelerating the airflow and increasing the diffuser effect.

A direct fit for 2014-2016 GT3 & GT3 RS models, but minor modifications could be required to match openings on the original engine cover. Due to the aggressive aerodynamic effects caused by this product, consult a race specialist to ensure aerodynamics are balanced for high speed or race applications.

Not compatible with standard 911 models.

Limited availability. Limited Stock.

Bolts Right On - 991.1 GT3
| April 3rd, 2024
Very easy to install; removed one rubber gromet from the 911R diffuser (same spot on OEM).
Fits perfectly on my GT3 RS

It bolted on in 10 minutes. The 991.2 GT3 has this part with no hole for the PDK pan so I figured cutting a vent hole would not be needed.
