STG Adjustable Rear Toe Link Arms | Cup Car Style | Porsche 981 & 718
Motorsport Precision for the Road and Track
The rear toe geometry of the Porsche 981 and 718 chassis is critical to mid-engined stability. Our String Theory Garage V4 Adjustable Rear Toe Links are the result of extensive development on the GT4 and Spyder platforms, offering a "Cup Car" style solution that far exceeds the durability and adjustability of the factory components.
By replacing the soft rubber bushings and limited eccentric adjusters with our motorsport-grade arms, you gain total control over your rear alignment. This is the ultimate solution for drivers who need precise, repeatable toe settings that won't "knock out" during high-G cornering or heavy kerb strikes.
The STG V4 Evolution
Our latest Version 4 (V4) design has been refined through years of setup work on the latest Porsche GT models. We believe these represent the best value-vs-performance toe link on the market today.
FK Stainless Steel Bearings: We spec ultra-high-grade, motorsport-spec FK bearings. Unlike cheaper spherical joints, these are designed for longevity and harsh environments, providing a silent but rigid connection.
Easy Adjustment: Featuring large hex turnbuckles that allow for a solid purchase with a spanner—making trackside "string" adjustments quick and effortless.
Better Than OEM: We utilize OEM-grade turnbuckles paired with outers that exceed factory strength specifications, finished for maximum corrosion resistance.
No Deflection: Eliminates the "squirm" felt under heavy braking and high-speed cornering caused by factory rubber bushes.
Vehicle Compatibility
These arms are a direct replacement for the following models:
At String Theory Garage, we don't just sell parts; we specialize in the geometry of the cars they fit. Installing adjustable toe links is the first step toward a bespoke track setup.
