BMW 4-Series F3x DYFI Fast Road Trackday Wide Bucket Seats 14-20

Vehicle-Specific Barbarian Racing Seat Package for BMW 4-Series 420i/430i/440i F3* 14-20

About the BMW F3x 4-Series Fitment

The F3x 4-Series is well suited to fast-road and track-oriented upgrades, and a more supportive seat helps make the driving position match the capability of the chassis. The complete package combines the selected seat with the required vehicle-specific fitting hardware.

Cabin and installation notes: Coupe-style cars place more emphasis on access to the rear, so a reclining seat can be a sensible choice for cars that still carry rear passengers. Fixed-back shells are better suited to more focused builds. Check shoulder width against the B-pillar and door trim before ordering.

Seat Model and Specification

DYFI Wide Fixed-Back Fibreglass Bucket Seat

The Barbarian Racing DYFI is built for drivers who need noticeably more room than the compact-shell seats. Its 56cm lower width, 59cm shoulder width and 34"-40" recommended waist range make it one of the widest seats in the Barbarian fixed-back range.

Why choose the DYFI? It is the natural alternative to the DRUID when the driver needs more hip, thigh and shoulder space. The performance-weave trim also gives it a more technical finish than the brushed-felt DRUID.
