BMW 4-Series 420i/430i/440i F3* SECA Bucket Seat Package 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

SECA Wide Fixed-Back Fibreglass Bucket Seat

The Barbarian Racing SECA is a roomier fixed-back option for drivers who want strong lateral support without the close fit of the narrower shells. Its 51cm lower width, 55cm shoulder width and 62cm maximum upper width make it one of the more generous fixed-back seats in the range.

Why choose the SECA? It suits larger drivers, or anyone who finds the HELL, DRUID or ASCARI too restrictive, while retaining a conventional open bucket-seat shape rather than the more enclosed head-restraint profile of the TOGE or 130R.
