For Your Driving Pleasure
RESEARCH & DEVELOPMENT – In order to provide the best products for the North and South American markets, TUSA established a full R&D center. Here all products are test fitted, and road tested to ensure not only performance and ride quality but also proper product fitment. TEIN's dedication and specialization to suspension components has led us to develop our street applications specifically for each region of the world. This means the TEIN products available from TUSA are not available in other parts of the world. The large majority of TUSA sales are to US consumers, and we have developed our street applications for the US market. This means the S.Tech, High.Tech, Basic, Super Street, Flex, and Mono Flex models were all developed and tested specifically for the Americas. Spring rates, valving, ride height, and ride height adjustability were all chosen for local (US & Canada) road conditions and consumer demands.
