Direct fit subframes for the Vauxhall Astra Mk2, also sold as the Kadett, fixing to the mounting points the car already has.
There are two listings for this car
This is the direct fit frame. We also list an adaption version at the same price, and the two are not the same thing: a direct fit frame replaces the car’s existing arrangement, an adaption part works alongside what is already there.
Which you want depends on what is still under your seat. If the car is complete and standard, this is normally the one. If a previous owner has already been in there, tell us what you find and we will confirm which suits before you order.
Included in the price
Base frame and sliding runner, in the price, where the other five makers sell the runner separately.
Seat compatibility
Cobra base mountable buckets and reclining sport seats, 291mm or 405mm wide handle. Not a side mounted seat without adaption bars or side mounts.
Tell us the seat at checkout. Priced per frame, which fits one seat.
Have you written anything useful for my car?
Yes: Top 5 reclining seat choices for your Vauxhall Astra Mk2, including our fitting guide. Those are written around the same car, from real fittings and customer questions, so they are worth a look before you decide.
Will this fit my car?
This frame is made for the Vauxhall Astra (Kadett) Mk2. Chassis code and years matter more than the badge, as floor pans change between generations, so if your car sits near a changeover year, send us the registration and we will confirm before you order.
Which seats does it take?
Cobra design each tailored frame around a particular seat, so check the Compatible seats tab above for the designed pairing. Other seats with a matching bolt pattern can work as cross-compatible components rather than a designed set, so ask us before mixing brands.
Do I keep fore-and-aft adjustment?
Yes, and unlike most brands the sliding runner comes included with a Cobra frame, in the price. That changes the like-for-like comparison against other makers, where the runner is a separate part on top. Our guide to sliding runners covers how they work.
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.
