Feal Coilovers, 90-04 Miata NA / NB
Default spring rates:
The NA/NB 441 kit was developed hand-in-hand with the pros over at Good Win Racing. With many years of driving Miata chassis, many podiums, and even a few track records under their belt, Good Win has a solid understanding of the Miata chassis. Good Win employee Ryan Passey even piloted his 442 equipped NA chassis to a track record on our local So Cal track Auto Club Speedway in Fontana, CA. We continuously work with Miata enthusiasts and Good Win Racing to ensure that you are getting the best coilover offering for your Miata.
Certain variations of the NB model may have a slight chance of clearance issue with the front upper control arm. Although statistically the instances are far and few, you can follow the link below for instructions on remedying the issue:
Each shock is designed with expertise from our success in many top-level international motorsports and through years of experience tuning various shock brands. We at Feal Suspension strongly believe that our coilovers have an edge on shock design that gives you confidence and a competitive advantage where needed most.
441 - Damping adjustability that adjusts Rebound and Compression in one knob. Very easy to tune vehicle firmness, dive, and roll.
442 - Separate damping adjustability for Rebound and Compression. Rebound adjustability does not change compression force so that you can fine tune the roll and rate of weight transfer. The huge range of compression adjustability is independent of rebound force. The compression adjustability will allow you to adjust for more or less traction and more or less suspension movement on the compression stroke.
443 - All of the above plus separate damping adjustability for High Speed Compression, Low Speed Compression, and Rebound. Low speed compression damping adjustability allows you to fine tune chassis movement on the compression stroke over round bumps and/or throttle and braking inputs. High speed compression adjustability allows you to fine tune bottoming resistance and wheel movement on the compression stroke over rumble strips and square edge bumps.
