How Porsche Made The 911 GT3 R Even Better

Porsche Motorsport’s approach to its GT3 customer car still leans heavily on mechanical refinement, incremental changes, and years of feedback from teams who run these cars in endurance series around the world.

Front-end behavior was the first target. The GT3 R’s double-wishbone setup was originally a major departure from past-generation 911 race cars, and Porsche has now paired it with reshaped louvres in the tops of the front wheel arches.

The goal is to better control pitch sensitivity, a key factor in how a race car behaves when braking from high speeds. Reducing the tendency for the nose to dive means the car remains more stable as downforce shifts and helps drivers commit deeper into braking zones without upsetting the chassis.

Rear aero and suspension changes were required to maintain that balance. Porsche has fitted a revised rear wing with a small 4-millimeter Gurney flap—an idea popularized in the 1970s by American racer Dan Gurney that remains a staple of motorsport aerodynamics. The tab sharpens the wing’s pressure differential, adding rear grip and increasing the range of adjustment teams can work with.

Beneath the car, the fully enclosed underbody has been strengthened, and at the rear axle, Porsche has altered suspension geometry to increase anti-squat under acceleration. That tweak helps settle the chassis when the driver rolls back onto the throttle, keeping the load distribution more even and tightening up the car’s transitions out of corners.

Steering feel hasn’t been ignored either. The GT3 R’s electrohydraulic power steering now benefits from liquid cooling to stabilize temperatures across stints, which in turn gives drivers a more consistent steering weight. That may sound minor, but during long races, consistency often matters more than peak performance.

Supporting hardware has been updated throughout: new ceramic wheel bearings, improved driveshaft cooling, and more accessible rear brake cooling adjustments. Porsche will also offer the upgrade package to existing GT3 R owners, ensuring older cars can be brought up to the new spec without requiring a complete replacement.

In a racing environment increasingly defined by energy recovery systems and complex electronics, Porsche’s latest revisions to the GT3 R are a reminder that traditional tuning—geometry, airflow, and mechanical grip—still forms the backbone of a fast and confidence-inspiring car.
