About Us

Built from obsession. Tuned for precision.

At SEB’S GARAGE, we don’t just work on cars—we live and breathe them. Whether it’s chasing tenths on the Nürburgring, obsessing over oil chemistry, or debating aero setups at midnight, our mission is simple: to build, maintain, and enhance performance cars without compromise.

Founded by Sebastiaan Asselberghs, MSc, PhD candidate with a background in science and a passion for motorsport, SEB’S GARAGE blends technical knowledge with real-world automotive and entrepreneurship experience. What started as a one-man obsession has grown into a workshop where no detail is too small and no corner is ever cut. The team is rich and young, we want to explore new cars and platforms, and do our own brakes from 130i 325i to fully built F82 and F80s at the workshop. Recently, we found more and more friends and familly trust us to do maintenance work on their cars and tire prep. We opened the workshop for everyone in May 2025 and are exceited to welcome you for tires, storage, or general workshop maintenance service throughout this season. Visit us at our humble premises, we're still making everything nice and tidy, and investing as we go along.

We specialize in high-performance street and track cars—from weekend warriors to full-on competition builds. Our services include:

• Track-prep & setup: suspension tuning, brake upgrades, corner balancing
• Performance lubrication: custom high-zinc oil formulations, fluid analysis
• Aero components & motorsport livery coordination
• Diagnostics & reliability engineering
• Component testing & R&D consulting

And yes, we build cars that get driven. Hard. We even crash sometimes but see this as a good learning and growing opportunity, to hone our workshop skills further!

If a job is too big for us, we outsource it to reputable partners at the Nürburgring, luckilly, Seb has made strong ties with motorsport shops and workshops, allowing us to offer any type of job. We don't touch important jobs ourselves, as we want to guarantee only the best quality service. 

We’re not interested in fluff. We’re interested in results.

Whether it’s a high-speed vibration caused by an unbalanced wheel, a camshaft worn out by low-ZDDP oil, or tire wear from poor geometry—we solve problems before they become failures.

Because in racing, failure isn’t an option.

You’ll see our builds around Nürburg, Spa, Zandvoort, and the backroads of Benelux. We work with clients across Europe, and our cars are often wrapped in bespoke motorsport liveries—carrying not only our brand but those of partners we trust.

We’re not a dealership. We’re not a parts shop.

We’re drivers, and detail freaks who care about every nut, bolt, and molecule of oil. Everything at SEB'S GARAGE started as adventures, trackdays or driftdays saddled us with workshop challenges, and we thought, we can do this to the extent and attention we want. We work on our own cars, from 130i 325i to next level F80 M3s, all to learn and grow as a young team of car enthusiasts!

At SEB’S GARAGE, we take performance seriously—but we keep the vibes real. You’ll find us under a car, covered in brake dust, sipping coffee, and talking compression ratios.

Whether you’re looking to prep your car for its first trackday or need support for a full race season, we’re here for it. Reach out. Stop by. Let’s build something that shreds.
