The Astra G (1998-2004) replaced the popular F-series and arrived on a significantly wider platform, giving it more interior room and different floor dimensions from its predecessor. The OPC variant launched with 190bhp from a 2.0 turbo, while the GSi 2.0 16V offered 136bhp in a more accessible package. Both drew interest from circuit drivers and the Astra G continues to appear in class-specific club racing categories. The Corbeau sub-frame for the Astra G is built to the G-series floor, which is a separate design from the equivalent kit for the outgoing Astra F.
The frame mounts directly to the Astra G’s standard floor bolting points. No drilling in most applications. ±10mm tolerance is standard, and minor adjustment is occasionally needed. Compatible with Corbeau base-mounted and reclining seats only; not for side-mounted FIA race seats.
£245 per seat position. Order twice for driver and passenger. Let us know your Corbeau seat model at checkout so we can verify the kit before dispatch.
