The TEIN Flex Z Coilovers are a complete ride-height adjustable coilover suspension kit engineered specifically for 93-96 Mazda RX-7 (FD3S). Built around TEIN’s twin-tube damper design and a full-length height adjustment system, Flex Z delivers a huge range of real-world adjustability for street builds and weekend performance driving.

Flex Z includes fully adjustable dampers with 16-step damping force adjustment (compression and rebound adjusted together) so you can tune the ride from comfortable daily use to a firmer sport feel. Kits include upper mounts/top hats where applicable (some vehicles reuse OE mounts), and spring preload is set from the factory as a baseline so installation is straightforward. If you want a dialed stance, better handling, and a more controlled ride without spending “race-only” money, Flex Z is the move.
