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.

There are many benefits to installing harnesses in your E82 -

  • 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
  • Schroth Quick-Fit harness integrates with standard tensioner and airbag logic
  • Quick Fit Pro tested and approved with HANS device

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 Schroth Quick Fit Pro tuning harnesses are the most advanced 4-point safety belt on the market. They are perfect for daily street or dual-duty street-track use. Quick Fit Pro harnesses mount with the existing female belt receptacles and the reinforced seat belt anchor points in the chassis. By using the standard receptacles the vehicle's SRS system remains active, adjusting airbag deployment and tensioner response accordingly. Other harnesses that do not clip into the stock belt recepacles may not integrate with the SRS with potentially harmful results. On factory BMW systems the SRS also employs a pyrotechnic charge that automatically tightens the belt in anticipation of a crash. All Schroth harnesses feature their asm technology that prevents your body from sliding under the lap belt and redces head and chest deceleration forces. Schroth has revolutionized the racing and tuning harness industry which is why you will find their safety belts on everything from rally cars to military helicopters.

Quick Fit and Quick Fit Pro harnesses are vehicle-specific with the correct anchor points and seat belt clips included. The main harness is easily un-clipped and removed from the car with almost no trace left behind. Quick Fit and Quick Fit Pro use different latch types with the Pro being compatible with a HANS device and a slightly better and safer overall design. All Schroth Quick Fit harnesses are TUV approved and meet US DOT seatbelt regulations.

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.

QuickFit Pro Harness Summary:

  • Suggested Use:  track, autocross, daily driver
  • Shoulder Belt:  2" pull down
  • Lap Belt:  2" pull down
  • Buckle:  FE cam lock push button
  • Installation:  click in/click out with stock receptacles; partial permanent bolt-in
  • Seat Compatability:  approved only for stock seats
  • HANS compatible?  Yes.

 

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.

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).

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
