An OMP direct fit subframe for the Vauxhall Astra Mk5. Part number HC850.

Mk5 specifically

Astra generations do not share floor mounting points. The fourth series takes a different part, so order on the generation rather than the model name.

Vauxhall in the UK and Opel everywhere else, the same car either way. If you have been searching under one badge and finding nothing, that is usually why.

The VXR is the one that gets built

Mk5 is the generation that brought it, and a VXR carries enough power through the front axle that the driver ends up working. A seat that lets you slide makes that harder than it needs to be, because you are steering and bracing with the same hands.

The standard seats are soft and sit high, which is the usual combination on a hot hatch of this era.

Both sides

The pair listing covers driver and passenger in one order, and it is worth taking if you are doing both, because it puts them at the same height.

The frame

Steel, base mount, bolting to the mounting points already in the floor. Nothing is drilled and the standard seats come out whole.

Two bolt patterns: 345mm by 271mm for Sparco, OMP and Corbeau base mount seats, and 405mm by 290mm for Recaro. Sold singly and handed.

What's included?

Photos are for illustration: It is very important to point out that the main product photos are entirely for illustration only. With over 1000 different frames available for different vehicles and applications, the manufacturer images provided are entirely illustration. What you receive may differ from this image.

What will be in the box? There are several types of seat frames which may be supplied depending on the vehicle and application. You may receive 1 of the following 4 types. If you are using them with a certain seat, please contact us in advance for professional advice.

#1. A full replacement frame with a sliding runner and resisitor kit
#2. A full replacement frame with a sliding runner
#3. A full replacement frame only
#4. An adaption bracket kit

Additional seat belt brackets: Each seat frame can be used for a variety of applications including road car reclining seats throuh to Motorsport FIA seats. Seat belt brackets are not required in a range of application so manufacturers generally do not supply them with their frame kits. If you require seat belt brackets please contact us in advance

NOT SUITABLE FOR OEM/FACTORY seats removed from other vehicles

Bolt point tolerances:

Please note that OMP, Sparco and various other brands have a +/- 10mm tolerance on the bolt point locations on each of their sub-frames. This means that when installing the equipment into your vehicle, you may find that one or more of the bolt points may need extending for a perfect fit.

This is normal and, when installed by a skilled professional, it may only add five minutes to the total installation time. A prime example is the OMP Renault Clio MK3 frames and the BMW E46 frames as two bolt points need extending by 5mm in 75% of installations.

Drilling of frames and equipment may be required to complete your installation.

Matching seats and frames:

There are over half a dozen different bolt patterns in the industry for base mounted seats. There are over 30 different bolt patterns for side mounted seats. Aftermarket frames from different brands will have different bolt location points.

Seats and frames are not a direct fit between brands. Seat frames are also not suitabled for OEM seats (Fitted into a vehicle from the factory) Please ensure to contact us for professional advice before purchasing your seat frames. We will be able to provide you a recommendation as to which seat frame is right for which seat.

Will I fit in this seat?
Send us your height and waist size and we will confirm the fit. how a seat actually feels to sit in is a different question, and our showroom team sit in these seats every day, so call us and we will give you the honest answer.

What do I need to fit it to my car?
The car-specific frame for your vehicle, plus a sliding runner if you want fore-and-aft adjustment. Our guide on base mount versus side mount walks through the whole stack, and tell us your car and we will quote the full kit.

How do I know it will feel right, not just fit on paper?
Makers publish widths and weights, never feel, and two seats with identical numbers can feel nothing alike. We keep the ranges on display in the showroom, you are welcome to come and sit in them, and our head support measurements guide shows the kind of real-world data we collect.
