Corbeau direct-fit sub-frames for the BMW E46 3-Series. Part code BMWE46.
The E46 ran from 1998 to 2006 across saloon, coupe, touring and convertible body styles. It is one of the most common cars on UK track days, partly because values make it accessible and partly because the chassis rewards driver input rather than correcting it electronically. Fitting a bucket seat is one of the first changes a track day E46 owner makes: the standard seat holds the driver adequately on the road but offers very little lateral support under cornering load. The E46 M3 in particular attracted serious owners from early on, and the seat is often the first upgrade after tyres.
These sub-frames bolt to the original E46 floor mounting points without cutting or drilling. The frame is built around Corbeau’s own bolt pattern, so it fits Corbeau seats directly and does not work with other brands. Standard seat runners come out, the sub-frame goes in their place, and the Corbeau seat drops onto the frame. Both driver and passenger positions are covered. The car can be returned to standard using the original floor fixings.
Price is for one sub-frame set. Seat is not included.
