718 GT4 «Lab Rat» Performance Package

This is the complete performance system for the Porsche 718 GT4. 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 Package and V11 Muffler. The result is +40 hp and +40 lb-ft you can feel through the rev range, with the flat-six wail to match.

Then we add the full carbon aero system, front splitter, swan neck rear wing, and dual dive planes — worth up to 1500 lbs of downforce, shaped to add grip without dragging the car down the straights.

Handling is redefined with the Dundon Track Day Setup Package and MCS 3-Way Dampers: fully adjustable tension arms and complete geometry control, plus independent high- and low-speed compression and rebound tuning. Race-car adjustability that still works on the road.

We finish with Forgeline GS1R forged wheels, cutting unsprung weight by up to 20% for sharper turn-in and better braking, and the PFC Track Day Brake Package for better bite, less fade, and the same pedal on lap twenty as on lap two.

The 718 GT4 LabRat Package is for the owner who drives their GT4 hard and wants the car to answer back. If you run track days, PCA TT, SCCA or club events, this is the setup we'd build for you. Balanced grip, stable aero, real torque everywhere, and brakes that hold up.
