What We Do

Performance Services For BMW & Porsche

Every build is track-validated, not just bolt-on.

01
Performance Tuning
ECU maps, dyno runs, and power calibration for BMW and Porsche. Every tune is track-validated, not just bench-tested.
02
Suspension Setup
Corner balancing, coilover installation, alignment for track use. We set your car up for how you actually drive it.
03
Race Prep
Cage work, harness installs, fire suppression, data loggers — if you're going wheel-to-wheel, we'll get you safe and legal.
04
Engine Builds
Stroker kits, head work, forced induction — custom builds for street or circuit. We've built race winners.
05
Brake Upgrades
Big brake kits, SS lines, race fluid flushes. Fade-free braking for track days starts with the right parts and setup.
06
Diagnostics & Repair
Even performance cars need maintenance. Factory-level tools at half the dealer rate.
Track Day Prep Packages

Why Lang Racing

Real Track
Experience Matters

We don't just bolt on parts. We build cars we trust at speed — and build yours the same way.

01
Race-Proven Knowledge
Lang's team has built cars competing in NASA, SCCA, and Spec events. We know what works under pressure at 120mph.
02
Porsche & BMW Specialists
We work exclusively on platforms we know deeply — M cars, 911s, Caymans, and the occasional track-day M5.
03
4.6 Stars. No Surprises.
100 clients later, built on realistic expectations, honest timelines, and builds that perform as promised.

"M3 suspension overhaul before track season. Bilstein coilovers, alignment, corner balance, brake flush. Set my personal best lap at MRLS. These guys know BMWs at the limit."

"Prepped my E46 for HPDE — found a cracked swaybar link that would have been catastrophic at speed. Fixed it, refreshed brakes, car was perfect all weekend."
