991.1 GT3

The 991.1 GT3 isn’t just another 911 — it’s Porsche’s first high-revving, rear-steering, dual-clutch-equipped track monster that blurred the line between road car and race car. With its screaming 9,000 RPM redline, aggressive aero, and laser-sharp chassis, it delivers precision like few others. But as every serious driver knows, it’s a starting point — not the final form.

This platform demands more when pushed hard. Rear tire temps skyrocket. OE toe links flex under load. The factory undertray scrapes on aggressive compression. Brake ducts can’t keep up. Sound familiar? That’s where we come in.

We’ve curated and engineered a full lineup of 991.1 GT3-specific upgrades designed to address real-world weaknesses and elevate performance where it matters most:

• Spherical suspension joints for sharper feedback and control

• Upgraded engine mounts to eliminate drivetrain slop at turn-in

• Aero enhancements that work with factory downforce, not against it

• Track-grade cooling for brakes, engine, and transmission

• Chassis reinforcements that add stiffness without NVH

Whether you're shaving tenths off a PB or just keeping the rear planted through Riverside at Buttonwillow, these parts are built for confidence at 10/10ths.

This isn’t just a parts collection — it’s the missing layer between what Porsche built and what the track demands.
