About ALTA Performance
ALTA Performance has been a cornerstone of the MINI Cooper aftermarket scene since its roots in the mid-1990s, when founder Adam Taft began selling import performance parts out of a home office in Beaverton, Oregon. What started as a passion project quickly grew into a full-fledged operation, and by the early 2000s ALTA had firmly planted its flag as a specialist in MINI Cooper performance engineering — designing, manufacturing, and supplying parts right here in the United States.
Today, ALTA Performance is recognized as one of the premier names in MINI Cooper modification. The brand's philosophy is straightforward: use only the finest materials, engineer products with precision, and manufacture domestically to ensure the highest standards of quality and performance. Whether you're building a spirited daily driver or a dedicated track-day machine, ALTA offers a comprehensive suite of upgrades to transform your MINI.
What ALTA Performance Makes
ALTA Performance covers virtually every aspect of MINI Cooper performance modification. Their product lineup includes cold air intake systems, cat-back exhaust systems, front-mount intercoolers, supercharger pulleys, suspension components, sway bars, end-links, control arm bushing kits, and turbo accessories. Each product category is engineered to work in concert, so enthusiasts can build a cohesive, well-balanced performance setup rather than a patchwork of mismatched parts.
- Cold Air Intakes: Laser-cut aluminum construction, CNC bent for precise fitment, with documented horsepower gains on boosted and naturally aspirated MINI engines.
- Exhaust Systems: Constructed entirely from 304 stainless steel for maximum corrosion resistance and durability, even under extreme heat cycles.
- Intercoolers: Engineered to maximize airflow from the front bumper opening, with precision powder coat finishes for long-term protection against the elements.
- Suspension Components: Sway bars, adjustable end-links, and control arm bushings made from solid steel with polyurethane bushings for sharper handling and improved turn-in response.
- Supercharger Pulleys & Turbo Accessories: Precision-engineered bolt-on upgrades for both supercharged R53 and turbocharged R56/R57 platforms.
Why Enthusiasts Trust ALTA
What sets ALTA apart in a crowded aftermarket is its commitment to domestic manufacturing and purpose-built engineering. Rather than sourcing generic components, ALTA designs its parts specifically for MINI Cooper platforms — accounting for the unique packaging constraints and performance characteristics of each generation. The result is a lineup that installs cleanly, performs consistently, and holds up over the long haul.
With a history spanning nearly three decades and a loyal following among MINI enthusiasts worldwide, ALTA Performance continues to be a go-to brand for anyone serious about unlocking the full potential of their MINI Cooper.
