Direct fit subframes for the BMW M3 E30, locating on the factory seat mounts, so nothing is cut.

Reversible, and on this car that matters

The frame bolts to the mounting points already in the floor. Nothing is drilled, nothing is cut, and the original seats go back whenever you want them to.

On an E30 M3 that is not a small point. The car has moved into the bracket where originality is priced, and a modification that leaves no trace behind it is the only sort worth making. Keep the standard seats stored flat and dry; they are part of the car now.

Included in the price

Base frame and sliding runner, in the price, where the other five makers all sell the runner separately.

Seat compatibility

Cobra base mountable buckets and reclining sport seats with a 291mm or 405mm wide handle. Not a side mounted seat without adaption bars or side mounts, and Motorsport seats and the Nogaro need side mounts.

Tell us the seat in the checkout comments so we can confirm the pairing. Priced per frame, which fits one seat.

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.

Have you written anything related to this?
Yes: Top 5 reclining seat choices for your BMW M3 (E30), including our fitting guide is worth a read before you order.

Will this fit my car?
This frame is made for the BMW M3 (E30). 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.

Availability

Cobra seats are handcrafted in the UK

Each seat is built to the specification you choose, which is why the wait is what it is: on average around 4 to 6 weeks, depending on the trim and options.

Cobra do not allow queue jumping. Orders are produced in the order they are received, so the earlier yours is placed the earlier it is built.

Made to your specification

Because each seat is made for your order rather than picked off a shelf, a made-to-specification seat cannot be cancelled once it is in production, and our special order terms apply.

Working to a date, or not sure which trim to pick? Ring us before you order. Getting the specification right at the start is far easier than changing it later.
