A pair of Sparco direct fit sub-frames for the three door Vauxhall Astra Mk5. Part number 00499024-X2.
Note the three door part. Body style changes the seat mounting on a good number of cars, and a frame cut for a three door will not necessarily suit a five door of the same generation. If your Astra is a five door, tell us before you order and we will check rather than guess.
Fitment
Steel, on the 345mm by 271mm base mount pattern, using the floor mounting points already in the car. Sparco, OMP and Corbeau base mount seats all share that spacing. The old same brand only claim on this range was not correct.
Side mount competition shells need side mounts or adaption bars over the frame.
Ordering
Both sides in one order, handed between driver and passenger.
Tell us the seats when you order. Frames in this range are either complete replacements or adaption bars depending on the car, and the photograph is illustrative.
In a three door the seat back tilt matters day to day, because you will be tipping the seat every time somebody gets in the back. If you are choosing between reclining seats, a rapid tilt lever is worth having. Showroom stock.
