What are the key differences between the standard 718 Cayman GT4 and the GT4 RS Weissach package?

Question

Accepted Answer

Here are the headline differences between the 718 Cayman GT4 and the GT4 RS Weissach:

1. Power & Performance
- GT4: 4.0 L flat-6, 420 PS, 8k rpm, 6-speed manual or PDK
- GT4 RS: same block but new internals, 500 PS, 9k rpm, 7-speed PDK only → 0-60 in ~3.2 s vs 3.9 s

2. Aero, Chassis & Weight
- RS swaps steel panels for carbon bonnet/liftgate, thinner glass, less sound-deadening → ~35 kg lighter
- Swan-neck rear wing, deeper front splitter, extra NACA ducts → ~60% more downforce
- Ball-joint top mounts, helper springs, rose-jointed rear suspension, bigger anti-roll bars
- 20" centre-lock forged wheels, larger steel brakes (optional PCCB carbon ceramics)

3. Weissach Package (on top of the RS)
- Exposed-carbon bonnet and rear wing, carbon window triangles, Race-Tex interior with contrasting stitching
- Indigo-blue accent logos, Alcantara steering-wheel marker, optional magnesium wheels for another ~10 kg saved

Net result: the RS is noticeably quicker, louder and sharper; the Weissach pack just turns the motorsport vibe up another notch while shaving a few extra kilos. Want help tracking down a GT4 or GT4 RS for sale?
