The Smart ForFour (2004 to 2006) is the first-generation ForFour, a front-engined, front-wheel-drive city car built on the W454 platform that Daimler developed jointly with Mitsubishi. It shares that platform with the Mitsubishi Colt of the same era. The ForFour is not a common track car, but it does appear at autocross and track day events, and the standard front seats are thin and offer very little lateral support. This listing covers the first-generation ForFour up to 2006 only. Later ForFour models use a different platform.
These sub-frames are matched to the first-gen ForFour’s floor fixing points. They are steel, they replace the OEM runners, and they accept a Corbeau base-mounted or reclining sport seat. The ForFour’s interior is tighter than it looks from outside, so checking the seat base width against the available cabin space before ordering is sensible.
Corbeau seats only. Side-mounted FIA competition seats do not use these frames.
