991.1 GT3 RS «Lab Rat» Performance Package

This is the complete performance system for the Porsche 991.1 GT3 RS. Every component is engineered, tested, and track-validated to work as a cohesive unit — not just standalone mods.

We start by unlocking real power with our D3 Street Power Package, which includes long-tube headers, a tuned intake, and our signature Lifetime Muffler and a Cobb Accessport with Dundon Pro Tune. The result? 

485whp Peak 

35 whp gains at 8200-8500 rpm

45lbft gains at 3000-5000 rpm

Then we add the Valkyrie Complete Aero Package — a full carbon aero system including a swan neck wing, dual dive planes, and a front splitter. This isn’t just for looks — you add more than 1500lbs of downforce at 160mph!

Handling is completely redefined with the Dundon Track Day Setup Package: titanium tie rods, caster and camber adjustability, adjustable end links, shims, and arms — plus MCS 3-Way Dampers that retain front axle lift and allow high- and low-speed compression plus rebound tuning. It’s precision race-car control with street-level usability.

We complete the system with 19" Forgeline GS1R lightweight forged wheels, reducing unsprung mass for better acceleration, braking, and chassis feel, and Performance Friction Track Day Braking system — the same used in pro-level racing — for serious stopping power with fade-free consistency.

Everything in this package is backed by engineering, data, and real-world track time. This isn’t a parts bin build — it’s a proven setup, developed through the same 3D scanning and modeling we use for our championship-winning clients.
