This is for a set of racing paddles for the BMW e46 M3 with the SMG II transmission. These beautifully vacuumed crafted paddles are made with carbon fiber and 6061 aircraft aluminum. Once you put these racing paddles on, you will never want to take them off again. It's the perfect item for track use and the bold design enhances the overall interior look.

You can wheel shift so much easier than the stock paddles. During turns, you can get a good 30% more rotation without having to remove your right hand and shift with these SMG lever. You can also wheel shift with your elbows resting on your legs since your fingers can reach the bottom of the paddles when your hands are placed on the lower (4:00 and 8:00) positions. So it's much more comfortable when just cruising, or when taking hard, tight turns. You can pretty much find these paddles on your steering wheel no matter where your hands are.

Replacing your SMG paddles is quite simple, and requires only a small allen wrench (we recommend a long "T-handle" style). As the SMG paddles do not connect to wires or switches in anyway, there is no wiring or difficult install required. This can be done in as little as 5 minutes.

In order to mount aftermarket seats in your car, you need a floor mount adapter. These high-quality aluminum adapters are made by Macht Schnell. These bolt to your existing seat mounting studs in the floor and offer the lowest profile of any floor mount (22mm height). This helps to keep your seat at the lowest position possible. Your seat adapters or sliders bolt to this adapter plate. These floor mounts are a matrix style with rows of threaded holes that allow you to find an ideal seat location. There are other options - including homemade - but these seat brackets for your BMW are the highest quality to match your expensive seats.

Sold per seat. Can be used on left or right sides of vehicle.

These adapters were originally designed for the E46 chassis. They can fit the E36 by modifying the mounting holes to match the bolt and stud locations on the E36 floor.

If you're going to use a 4 point racing harness with your racing or sport seat and don't want to drill through your floor and carpet, these harness adapter plates are perfect*. These sandwich in between your slider and seat bracket for a strong and secure mounting point. They are made from high-strength steel and powedercoated in stealthy black. Choose from a bolt-in or clip-in style harness end. These will only work with the Macht Schnell floor mounts.

* - note that most racing harness manufacturers will advise that drilling through the floor is the best method for mounting harnesses. This allows you to locate the mount in the ideal location and angle to fit your driving position. The proper installation is paramount to ensure the harness works correctly in an impact.

Many racing series and event organizers are requiring 5 or 6-point harnesses in their events now. Attaching the anchor points to the seat base is a desired alternative to drilling holes in your floor and carpet*. This set includes the 6-point anchor to attach to the Macht Schnell floor mount as well as side attachments for either a bolt-in or snap-in harness.

* - note that most racing harness manufacturers will advise that drilling through the floor is the best method for mounting harnesses. This allows you to locate the mount in the ideal location and angle to fit your driving position. The proper installation is paramount to ensure the harness works correctly in an impact.
