A group of friends who live and breathe cars.
Based out of Hemet, California, we're a team of enthusiasts who all come from different backgrounds, different experiences, and different walks of life. Some of us were born and raised here in the valley, while others found their way here over the years. The one thing we all had in common? A passion for cars.
Ironically, we all ended up building some pretty wild BMWs along the way.
What started as working on our own vehicles in driveways and garages quickly turned into helping friends, then friends of friends, and eventually building a reputation throughout the Inland Empire. We saw too many shops cutting corners, rushing repairs, and charging customers without delivering quality work. So we decided to do things differently.
At Built Better Performance, every vehicle is treated like it's our own. Whether it's a European, JDM, or American platform, we take pride in providing honest diagnostics, quality repairs, and attention to detail that you can trust.
From routine maintenance and electrical diagnostics to engine swaps, drivetrain work, and performance upgrades — we've worked on just about everything. No matter what you drive, our goal is simple: do the job right the first time and keep our local car community moving forward.
Built in the Inland Empire. Driven by passion. Built Better.
