SUB2 SpeedHouse is a curated performance parts destination and build consultancy founded by Alex Bernstein—also known in the automotive world as @bernooo. With over 15 years of industry experience as a commercial automotive photographer, director, and lifelong enthusiast, Alex brings a unique blend of creative vision and technical insight to every build.

Born from a deep passion for BMW M cars and time attack performance, SUB2 SpeedHouse was never intended as a business-first venture—it’s a purpose-driven project built by and for enthusiasts. After years of navigating misinformation across forums and social media, Alex recognized a widespread need for clear guidance, trusted recommendations, and proven parts—all in one place.

SUB2 SpeedHouse simplifies the build process by offering only the highest-quality components from respected brands—parts tested and used on in-house vehicles. The philosophy is simple: eliminate guesswork and deliver results. No replicas. No gimmicks. Just the right tools, expert support, and a track-focused mindset to help clients unlock the true potential of their cars.

Whether you're starting your first project or aiming to shave seconds off your PB, SUB2 SpeedHouse provides end-to-end support for BMW M platforms and the A90 Supra. The brand's motto, “Buy once, cry once,” reflects its commitment to doing things right the first time—with precision, performance, and integrity.

Welcome to SUB2 SpeedHouse. Built for lap times. Backed by passion.
