An OMP direct fit subframe for the Vauxhall and Opel Astra, second series. Part number HC737.
This is the base part. A third series listing sits under HC737-2705, and that one carries contradictory year data we are currently correcting, so if you are choosing between the two, send us the registration.
The Mk2 Astra
Built from 1984 to 1991, and the generation with the GTE 16v, which was a genuinely quick car in period and is now scarce. The Astra has a long history in British touring car racing that keeps interest alive in the older shells.
In Europe the same car is the Kadett E, so if you are researching parts, search both names.
Practical
These rust comprehensively and very few good ones survive. Get the carpet up and look properly at the metal round the mounting points before you spend anything.
What else you need
Side mounts and the seat. Steel, black powder coat, no bolts. Both bolt patterns drilled, so OMP, Sparco and Corbeau shells fit alongside Recaro.
Will this fit my car?
This frame is car-specific, so match the vehicle in the product name to your exact car and generation. If you are unsure, send us the registration and we will confirm before you order.
Which seats does it take?
It takes seats drilled 345mm x 271mm (the Sparco and OMP seat pattern) and 405mm x 290mm (the Recaro seat pattern). If your seat is not listed, tell us what you run and we will confirm the fit.
Do I keep fore-and-aft adjustment?
Only with a sliding runner between the frame and the seat, which is a separate part on OMP frames. If more than one person drives the car, budget for the runner. Our guide to sliding runners explains the options and widths.
Base mount or side mount, and does it matter?
This is a base-mount frame: the seat bolts down through its base, the simpler stack that suits seats with a flat bottom and keeps the install low-fuss. Our guide on base mount versus side mount explains the whole fitting stack.
Is this for the driver or passenger side?
Both sides are available on this listing, pick driver or passenger side at the point of order (sides listed are for right-hand-drive cars). Left-hand-drive car? Ask us, as the sides swap over and availability varies by model.
