After-market seats like the Corbeau Boss reclining sport seats are fitted in a vehicle using a fitment frame or more commonly known as a subframe. A subframe is an interface between the unique fixing points of a specific vehicle model and the base of an aftermarket seat. Tailor made frames are specifically made to use the original bolt points of the original seats to attach the new seat. This allows quick fitting with no modifications required.
Which sub frame to use?
We strongly recommend you only use the correct subframe for the correct seat. If you have a Cobra Daytona reclining car seat as shown in this photos, we recommend using a Cobra sub frame for your car to make sure fitment is 100% perfect.
By using the correct branded products fitment will be straight forward and all bolt holes will line up for easy fitment to your sports seats and your car.
How to bolt them to your car
Sub frames come in all shapes and sizes depending on the shape of your cars floor plan. These bolt directly into your original bolt points to create an extremely secure and safe seating position. No custom fitting should be required.
Sub frames are commonly and primarily used for road use for this reason. They are not FIA approved when fitting sports seats or racing seats to a vehicle but they are MOT legal.
What will you receive?
When choosing your make and model from the fitting option lists with some of the seats you will notice the manufacturers list letters which relating to the following items:
Cobra Seats : A-E = Tailor made frames, R = Runners only, U = Universal frames only, H = Adaptation frame and original parts required.
Can I use them with reclining sport seats?
Reclining sport seats are commonly based mounted and require subframes for fitment and not side mounts. So the simple answer is yes, only a small range of bucket seats allow for this kind of fitment and most commonly use side mounts. Please click here to refer to the side mount information.
What adjustments are available?
All sub frames shown on our site allow for sliding back and forth. This allows greater flexibility when it comes to fitting and different height drivers.
Some frames also allow a tilt mechanism when using base mounted bucket seats for more access to the rear as bucket seats do not have a built in tilt mechanism like reclining car seats.

If you found some seats that look great in another car as standard like the Civic Type R or some Recaro seats from a Cosworth and want to put them in your car. Sadly we won't be able to help with subframes.
All subframes are tailor made from each manufacturer to fit their own specialist seats. This means bolt holes and fitments may be very different to the seats you are wanting to install. In this case we would recommend custom work.
Which brand of bucket seats are available with sub frame fitments?
The following brands all make sport seats and reclining car seats with base mounted sub frame fitments:
What happens if direct fitment frames are not available for my car?
There are many cars on the market where direct subframes are not available. However if you still want to replace the seats in your car and your car is not listed there is only one option for a safe and secure fitting.
We recommend you choose the seat you like the look of the best and use a local garage to modify your original seat frame to bolt to the new seat. This may take some fabrication work and a small bit of time but should be worth it for the finished effect and provide you with exactly what you want.
