The E28 5 Series (1981-1988) and E24 6 Series (1976-1989) share a closely related floor plan, which is why Corbeau supply one sub-frame kit for both models. The E28 included the M535i with 218bhp and the M5 with 286bhp from the M88/S38 engine. The E24 6 Series carried the M635CSi with 286bhp from the same engine family. Both remain highly regarded by BMW enthusiasts and track-day drivers. The sub-frame works with the standard floor of either car without requiring modifications to the bodyshell, using the existing hole positions in both models.
The kit mounts to the original E28/E24 floor fixings without drilling in most applications. ±10mm bolt tolerance applies, and minor adjustment is occasionally needed. Corbeau base-mounted and reclining seats only; not for side-mounted FIA seats.
£245 per seat. Order twice for both positions and confirm each side. Tell us which Corbeau seat at checkout.
