ABOUT MST PERFORMANCE AUTO PARTS
HISTORY
Founded in 2011 and based in Tainan, Taiwan, MST Performance was created from a lifelong passion for automotive engineering.
The founder, Mr Chiang, began his journey modifying motorcycles before moving into cars, where his desire to improve performance led him to design his own intake systems.
Starting with Ford Focus models for himself and friends, his first products delivered outstanding results and fuelled MST’s growth. A commitment to developing high-quality, performance-focused parts quickly became the cornerstone of the company’s success.
THE MST MISSION
MST aims to develop premium-quality automotive performance parts for enthusiasts around the world. Since 2011, MST Performance has pushed the limits of intake system design and construction through continuous innovation and rigorous testing.
From prototype to production, every MST product is dyno-tested and road-tested to ensure maximum efficiency, durability, and performance. The MST philosophy focuses on achieving strong power gains throughout the RPM range, enhancing the overall driving experience rather than chasing peak horsepower alone.
MST remains dedicated to producing innovative products at the forefront of the market, expanding thoughtfully while maintaining a steadfast commitment to quality and customer service.

Sean arranged a Quaife LSD for my 135i and I couldn't be happier. He advised multiple seals and bearings needed replacing unbeknownst to me so these were done as well. Now I have a more reliable car and one with tonnes more mechanical grip!

Fantastic customer service from the team at Southern BM. Expertly repaired my 2011 323i and did so without the attitude and excessive cost of a dealer. Thank you and I will be back for all future servicing.
