Porsche 718 Cayman GT4 RS: Where “Road Car” and “Race Car” Shake Hands

Where the GT4 RS “falls” in racing: GT4, and the Cayman GT4 RS Clubsport

The road-going 718 Cayman GT4 RS is the street car: 493 hp, 0–60 in 3.2 sec, 196 mph top track speed.

The race world mainly revolves around the 718 Cayman GT4 RS Clubsport, which Porsche introduced as a customer race car with a 4.0-liter engine derived from the 911 GT3 Cup and around 500 hp, built for GT4 competition.

Key series where you’ll see the Cayman GT4 RS Clubsport (GT4 class)

You’ll typically find it in:

• IMSA Michelin Pilot Challenge (Grand Sport / GS class in the U.S.)
• Pirelli GT4 America (SRO America)
• GT4 European Series (SRO Europe)
• ADAC GT4 Germany (where Porsche noted major Cayman GT4 RS Clubsport success)

Top teams racing the Cayman GT4 RS (by series)

IMSA Michelin Pilot Challenge (GS)

A few of the most visible Porsche-running operations in 2025 included:

• RennSport1 (RS1) – a headline Porsche GS team with the Cayman GT4 RS Clubsport
• Unitronic/JDC-Miller MotorSports – Porsche Cayman GT4 RS Clubsport in GS

(IMSA’s results pages and season entry lists routinely show the Cayman GT4 RS Clubsport among GS entries, including the Porsche-running teams above.)

Pirelli GT4 America (SRO)

Notable Porsche Cayman GT4 RS Clubsport teams in 2025 included:

• ACI Motorsports – repeatedly referenced in GT4 America race reports in Porsche Cayman GT4 RS Clubsport entries
• NOLASPORT – confirmed running the Porsche 718 Cayman GT4 RS Clubsport in series coverage
• VPX Motorsport – referenced as a Porsche Cayman GT4 RS Clubsport entry in season reports

Europe and Germany: GT4 European Series / ADAC GT4 Germany

On the European side, Porsche Cayman GT4 RS Clubsport teams include:

• W&S Motorsport – Porsche highlights W&S as sweeping all titles in ADAC GT4 Germany with the Cayman GT4 RS Clubsport
• AV Racing – listed as a Porsche 718 Cayman GT4 RS Clubsport team in GT4 European Series entries

2025 podiums: what the Cayman GT4 RS Clubsport accomplished

Here’s the tricky part: you asked for podiums for 2025, and that can mean either:

1. Podiums in a specific championship, or
2. Overall podium volume across customer racing worldwide.

Good news: we can cover both, using published sources.

“Big picture” 2025: podium volume across GT4 racing

Porsche stated (in a September 2025 customer racing update) that the GT4 RS Clubsport had notched over 200 podiums from more than 550 race starts, and highlighted W&S Motorsport sweeping all titles in ADAC GT4 Germany. ([Porsche Motorsport Hub][7]) That same Porsche update also noted 103 podium finishes “so far this season” from more than 400 race starts (context: 2025 season progress).

“Series-specific” 2025: IMSA Michelin Pilot Challenge (GS) Porsche wins (podium highlights)

One of the cleanest, well-documented ways to show 2025 podium success is to point to race wins (top of the podium) by Porsche Cayman GT4 RS Clubsport teams.

• RS1 (RennSport1) won at VIR in GS with its Porsche Cayman GT4 RS Clubsport (IMSA race report + supporting coverage).
• Porsche’s own North American newsroom recap noted RS1 earned its third GS victory of the season in the Cayman GT4 RS Clubsport.
• Season-level results tables list additional Porsche GS wins (including RS1 wins at venues like Laguna Seca and Watkins Glen).

“Series-specific” 2025: GT4 America Porsche podium mentions

GT4 America race reports repeatedly place the Porsche Cayman GT4 RS Clubsport at or near the front in class battles (including ACI Motorsports leading overall early in a Road America report). And team communications also reference end-of-season podium efforts (example: ACI’s own release around Indianapolis).

If you want, I can tighten the 2025 podium section further to one championship only (IMSA or GT4 America or GT4 Europe) and list every Porsche podium from official results pages—but that becomes a long ledger.

The GT4 RS itself: what makes it special on the street

Porsche’s own headline numbers for the 718 Cayman GT4 RS are already spicy:

• 493 hp
• 0–60 mph in 3.2 seconds
• 196 mph top track speed

The character is what hooks people: mid-engine balance, a high-revving flat-six, and aero/intake sound that feels more “pit lane” than “country club.”

And crucially: it acts like a bridge. You can drive the GT4 RS to dinner, but it’s also the spiritual showroom partner to the Clubsport race car Porsche sells to teams.

GT4 RS vs GT3 RS: same attitude, totally different physics

If the GT4 RS is a track tool you can live with, the 911 GT3 RS is Porsche’s “what if we turned downforce into a personality trait?” machine.

718 Cayman GT4 RS (mid-engine, “precision first”)

• Layout: mid-engine (neutral balance, incredible rotation)
• Power: 493 hp
• Top speed: 196 mph
• Vibe: the car feels like it pivots around your hips—fast responses, compact footprint, “point-and-shoot” with finesse.

911 GT3 RS (rear-engine, “aero first”)

• Layout: rear-engine (traction monster, unique feel under braking/turn-in)
• Power: 518 hp
• 0–60: 3.0 seconds
• Top speed: 184 mph
• Vibe: it’s less about top speed and more about how hard it can press the tires into the planet with aero and chassis tuning.

The practical difference

• The GT4 RS is the “driver’s rhythm” car—lighter feel, mid-engine poise, huge engagement for real roads and track days.
• The GT3 RS is the “lap time religion” car—more extreme aero philosophy, bigger presence, and often more punishing outside the track context.

They’re both brilliant. They’re just brilliant in different dialects of Porsche.

Why teams and series love the Cayman GT4 RS Clubsport

GT4 racing exists because it offers a relatively controlled, customer-friendly rung of sports car competition—fast enough to be serious, stable enough to be sustainable.

Porsche’s own writeups emphasize that the Cayman GT4 RS Clubsport draws directly from Porsche’s racing pipeline (engine lineage from the 911 GT3 Cup), and then backs it with a global customer racing ecosystem.

And the results show it: Porsche points to wins, titles, and huge podium volume—not as marketing fluff, but as the natural byproduct of a car that teams can run hard without turning every weekend into an engineering crisis.

Closing thought

The GT4 RS is a road car that feels like it’s constantly trying to talk you into “just one more lap.” The GT4 RS Clubsport is what happens when that idea is handed to teams and turned into a global racing tool—IMSA, SRO America, SRO Europe, ADAC—pick your battleground.
