718 Cayman GT4 RS

The first Cayman to wear RS.

Hey — good to see you. Come stand here a second.

This is the 718 Cayman GT4 RS. The first Cayman Porsche ever let wear those two letters: RS. There’s a real reason for that — let us walk you through it.

Redline · Bangkok

Quick bit of history first, so it all makes sense.

2015

981 Cayman GT4

3.8L · 385 PS

The first one. A 3.8 flat-six, a manual, and proof a Cayman could really go.

2016

Cayman GT4 Clubsport

Motorsport

Same idea, but built to race. The Cayman heads into the GT4 class.

2019

718 Cayman GT4

4.0L · 420 PS

A bigger 4.0 six. The press basically called it an instant classic.

2021

718 Cayman GT4 RS

4.0L · 500 PS

Then someone asked: what if we drop the GT3 engine in? And here we are.

The heart
Redline · Bangkok

Start with the engine — it’s the whole point.

It’s the 4.0 flat-six straight out of the 911 GT3. No turbo, revs to 9,000. And the intakes sit right behind your head — so you don’t just hear it, you feel it.

It’s a little unhinged. In the best way.

Porsche 718 Cayman GT4 RS — swan-neck rear wing and aero
The wing & the air
Redline · Bangkok

See the wing? It’s mounted from the top — swan-neck, like the race cars. Cleaner air underneath.

None of it’s for show. The ducts, the splitter, the diffuser — all doing a job. And it’s 35 kg lighter than a normal GT4.

Redline · Bangkok

The numbers: 0–100 in 3.4, tops out at 315.

Round the Nürburgring it ran about seven-oh-four. Roughly 23 seconds quicker than the regular GT4 — that’s a huge gap for the same shape.

Redline · Bangkok

Climb in. Race-Tex, carbon buckets that actually hold you, a yellow marker at twelve o’clock.

Nothing in here you don’t need. That’s kind of the point.
