Installing seats is one of the most noticeable changes you can make to your Bmw M3. Keep in mind, though, that seats almost never mount up to your factory seat brackets. This means that installing seats (aka buckets seats) in your Bmw M3 requires you to buy not only the seats but also the brackets, which are sold separately. If you have any questions about how to install Bmw M3 seats, please call us at 1-800-419-1152.
