Corbeau direct-fit sub-frames for the BMW 1 Series. Part code BMW1SERIES.
The BMW 1 Series is the rear-wheel-drive small BMW, sitting below the 3-Series in the range but sharing the same drive layout. The 1M and later 135i have a strong following in track day use and club motorsport, and the body’s lighter weight makes it a genuinely competitive tool at the right spec. The standard Sport seat leaves the driver sliding during hard cornering, and a bucket seat is one of the first changes drivers make for circuit use.
These sub-frames bolt to the original 1 Series floor fixing points without modification. Corbeau-seat-specific bolt pattern, not cross-brand compatible. Both driver and passenger positions covered.
Price is for one sub-frame set. Seat is not included.
