In the performance automotive world, having access to the right components can make all the difference. For workshops, engine builders, performance retailers and race teams, the challenge isn’t simply finding quality parts. It’s finding a reliable supplier, maintaining healthy margins and being able to give customers access to components that are designed for serious performance.

A performance camshaft is one of the most effective upgrades you can make to an engine. Whether you’re building a responsive street car, a powerful weekend toy, or a dedicated competition vehicle, a camshaft upgrade can unlock significant performance gains by improving airflow and optimizing the engine’s power delivery. However, a camshaft is only one

When building a performance engine, the camshaft is one of the most important components in the entire setup. It determines how your engine breathes, where it makes power, how aggressive it sounds, and whether the car feels enjoyable on the street or only comes alive at high RPM. At STK Performance, the camshaft range is

When building a turbo Opel Corsa 8-valve engine, one of the biggest restrictions in the setup is often the factory camshaft. While the standard cam profile is designed for smooth daily driving, fuel economy, and reliability, it quickly becomes a limitation once boost, airflow, and performance upgrades are introduced.

When it comes to pushing the legendary Nissan SR20 engine beyond factory limits, most builders focus on turbos, fuel systems, and tuning. But one of the most overlooked — and most critical — components in a high-performance engine is the valvetrain. And more specifically… the valve springs. If you’re chasing higher RPM, bigger cams, or

When it comes to performance and reliability, most enthusiasts focus on big upgrades—cams, turbos, injectors. But often, the real problem lies in the smallest components. In the case of VW 16V engines, one of the most overlooked culprits behind poor performance, noise, and long-term engine damage is the cam follower. And more importantly—the right hydraulic
