What is on this page
What has changed on the BMW cages
Every SW Motorsports BMW cage on our site has been checked and rewritten. The listings now say what each cage is built to, how it is made and which models it fits, so you can see quickly whether it suits your car.
SW Motorsports bolt-in cages are a popular choice for track day drivers. SW build them from the same materials they use for their own race cars, and they add a good level of protection in the event of a roll. The range runs from the E36 Compact and E46 through the 1, 2, 3 and 4 Series to the F80 M3 and G82 M4.
Rear half cages
The half cages have no door bars. They reinforce the rear of the car and leave the front of the cabin as it was, which suits a BMW that still does road miles as well as track days.
They are designed to go in at home with a basic set of tools and no welding. Each comes with all the fittings and fixings needed, and can be powder coated in a range of colours. The tube is 45mm x 2.5mm CDS to the E355+N specification the Motorsport UK regulations call for. For the E46, E92, F21, F22 and F82 there are full bolt-in cages too, built to Motorsport UK regulations.

Seat delete kits
Once the rear seats are out and a cage is in, the bare bodywork is on show. SW's seat delete kits solve that. They are 3D scanned and CNC cut to fit around their own cages, and finished in black carpet, so the rear of the car looks tidy and finished.
Kits are made for cars including the E82, F20, M2, F80 M3, M4 and M6. Garreth's advice is to order the cage and the kit together, since the kit is shaped around that cage.

A showroom discount on seat mounts
In the showroom we hold M2 and SW Motorsports side mounts and all-in-one fitting kits, ready to dispatch or collect, including frames for popular cars such as the Renault Megane Mk2. For a limited time, every SW Motorsports side mount and M2 frame we hold in store has 15% off, applied automatically at the checkout.
Before choosing a cage for competition, check your championship’s rules. Our guide to roll cage rules explains the basics, and our SW Motorsports roll cage range lists every car we cover.
