Product Details
The ISR Performance Pro Series Coilovers for the 1986-1991 Mazda RX-7 (FC3S) drop your ride height, sharpen turn-in response, and pull the chassis together without beating you up on the commute. Built around a monotube shock body with 32 clicks of rebound adjustment, these Mazda RX-7 coilovers give you the range to set the car up softly for daily driving and crank it back down for a canyon run or track weekend.
Every Pro Series Coilovers kit ships with pillowball front upper mounts for precise camber control, high-end Japanese internal bearings, and a spanner wrench to tune ride height at home. Whether you're running the FC3S RX-7 at a local grassroots drift event, carving through back roads, or simply wanting a cleaner stance and tighter feel, ISR Pro coilovers deliver factory-quality fitment with aftermarket performance.
