Collection: Builds, Tuning Packages & Tunes
FJ Motorwerkes – Performance Tuning You Can Trust
At FJ Motorwerkes, we specialise in BMW tuning and performance packages built through years of real-world experience, obsessive data refinement, and a drive to deliver results, not excuses.
We’re a small, independent operation, but we punch far above our weight. Whether it’s breaking records on the street, setting times on the strip, or featuring on YouTube’s biggest automotive platforms, our work consistently proves itself where it counts: in the real world.
Tested by Us. Proven by Results.
Every package we sell is tested first on our own cars. From turbo upgrades to ECU calibration, we run it hard before offering it to you. No dyno queens. No one-hit wonders. We chase consistent, usable performance that works every single time — on the road, not just on paper.
Our Proven Track Records;
- Fastest BMW X3M in the UK (2021 - 2023)
- Fastest Stage 1 only BMW M5 F90 in the UK (2020) Verified 10.4s ¼ mile
- Fastest Porsche 992 Carrera S in the UK Verified 5.85s 100–200 Dragy
- Winning multiple trophies across UK drag events
- Featured on AutoTopNL, Living Life Fast, and Officially Gassed
Unlike others who’ve been exposed or fall short when the cameras roll, we’ve kept a clean sheet — because we don’t cut corners. Whether it takes 3 logs or 45, we’ll get it perfect. Our name is attached — and that means everything.
