Upgrade your BMW's safety features with the Rallye Cross harness from Schroth. This 4-point harness features Schroth's patented ASM technology, ensuring optimal safety during track driving. Unlike Rallye 3 or 4 harnesses, the Rallye Cross boasts independent shoulder straps that go directly to the mounting point, eliminating the need for quick disconnect buckles. Perfect for track driving in cars with no back seats, this harness is compatible with stock seats and offers a safe harness solution. Please ensure proper structural reinforcement for the shoulder strap mounting points. Contact us for installation inquiries.
There are many benefits to installing harnesses in your BMW -
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:
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.
