BMW Seat Belts and Racing Harnesses for BMW 3 Series G20 (2019+)

Clear BMW chassis

Please ensure your correct model is selected

The advantage of racing harnesses cannot be understated. Aside from the obvious improvement to your safety, harnesses keep your body planted in the seat and allow a much more confident and focused driving experience. Without your body strapped in you're constantly fighting to keep youself planted in the seat and these forces distract you from controlling the car. It also prevents you from getting and maintaining the ideal leverage point for working the steering wheel and pedals. Turner Motorsports offers several harness and seat belt accessories to make the use of harness belts easier.

There are many benefits to installing harnesses in your BMW -

  • maintain a proper driving position
  • keep you planted in the seat and not bracing with your left leg or shoulder
  • lower lap times thanks to improved driver confidence
  • advanced technology is safer than standard 3-point belts

It's hard to put into words just how effective harnesses are in improving your driving experience. In addition to the obvious safety benefits, harnesses make you a better driver by removing distractions so your hands and feet are used for car control instead of bracing against a door panel or dead pedal. Everyone with harnesses will agree: they are a must-have upgrade to your driving experience and they wish they had installed them sooner.

The Rallye harnesses are Schroth's universal fit, bolt-in harness design that still meets DOT and TUV specs. The Rallye 4 harness fits most BMWs better than a Rallye 3 type thanks to its four mounting points that bolt to four existing anchor points in the BMW chassis: outboard lap belt anchor on B-pillar, inboard lap belt anchor on seat, and both rear seat belt anchors. The Rallye harnesses are a fixed, semi-permanent install but a quick-connect buckle is included in the rear seat harness so that the front and rear sections can be separated and tucked away when not in use. This also allows you to use the stock 3-point seatbelts in the front and rear seats without obstruction. All Schroth harnesses feature their asm technology that prevents your body from sliding under the lap belt and redces head and chest deceleration forces. Rallye belts are not side-specific; they fit either the Left or Right side of the vehicle.

Optional: Schroth Grips. Schroth harness grips slide into the ends of your Schroth harnesses and give your fingers something to lock onto when tightening the harness. Otherwise, your hand - or glove - has to yank on the end of the strap which might be slippery. Sold per harness for both shoulder and both lap belts (4 Grips total).

Seat Compatability: Schroth approves this harness only for stock seats or seats that have passed independent crash testing. The seat design must have a separate headrest and backrest. Single piece headrest and backrest (e.g. - F8X M3/M4 seats, Porsche 911 seats) are not approved because the shoulder straps fall to the sides and will not secure the driver properly. Observe all guidelines and instructions for installation and fitment.

E36 Fitment Note: a special bolt is required for installation on the stock E36 seat. Make sure you order this bolt for any E36 installations. Click here for the link to the bolt.

Rallye 4 Harness Summary:

  • Suggested Use:  autocross, daily driver
  • Shoulder Belt:  2" pull down
  • Lap Belt:  2" pull down
  • Buckle:  Rallye push button
  • Installation:  permanent bolt-in
  • Seat Compatability:  approved only for stock seats with headrest separated from backrest
  • HANS compatible?  No.

 

When using any racing harness in any environment - even normal street use - adhere to this advice: "all the way tight, all of the time". Never loosen or slacken the belts for comfort or convenience! A loose racing harness will not protect you.

The Profi II ASM is designed to be used as a four-point system. For this reason it is perfect for use in Driver Education cars or any other application where stock seats are retained. A seat that was not originally designed for use with a racing restraint should never be modified to accept a sub strap. The Profi II ASM incorporates Schroth's legendary ASM (Anti-SubMarining) technology that is the only thing like it on the market. ASM is an extra fold of material sewn into the right shoulder belt that elongates at a different rate than the outboard belt. This allows your upper torso to twist slightly. On the rebound phase, your torso is planted firmly back in the seat rather than allowed to slide under the lap belt. The Profi II ASM shoulder is only available in 3" width but is still suitable for use with a Forward Neck Restraint such as a HANS device You can add a dual sub strap to make this belt into a 6 point at any time. Schroth has recently tested this harness with a HANS device, and the results were great. So you can in fact use this harness with a HANS device. Another feature unique to the Profi Series 2" lap belts is the "Flexi Belt". The End Fittings and Cam Latches are wrapped into the harness, making it so that the lap belt can be changed from a Pull-Up configuration to a Pull-Down. This allows you to set the belt up just the way you want it for your specific situation. It also allows for Bolt In brackets to be wrapped in for the lap belts if needed. Snap-in brackets come standard on the laps. The Shoulders come ready to wrap around a roll bar. Snap-in or Bolt-in attachments can be bought separately. The Lap Belts come with Snap-in Attachments. Bolt-in brackets can be wrapped in if necessary.
