BMW F80 M3 S55 3.0L

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.

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.

APEX ARC-8 18" Staggered Wheel Set -- 18x8.5" / 18x9.5"

This set of 8.5" and 9.5" ARC-8 wheels is an easy staggered fitment for the E46 M3 and Z4M models. These are a direct fit with no spacers or fender rolling required. We use an 8.5" ET38 on the front and a 9.5" ET22 on the rear. These are only slightly wider than the stock sizes. The rear wheels have a deeper concave face than the fronts, emphasizing the RWD chassis and adding some muscularity to the stance.

APEX light alloy wheels are the next evolution in flow-forged wheel technology for BMWs. Flow-forming is a semi-forging process that produces a wheel typically stronger than a traditional cast wheel yet is still light weight. The wheels are around 10lbs lighter per wheel than a comparable factory wheel! That's reduced unsprung weight that improves all aspects of performance. The spokes and barrel have been designed to allow generous clearance for big brakes. In other words, these wheels are very impressively engineered and look great too! The design is based on classic motorsport themes that blend with BMW styling and appearance. These wheels look right at home on many BMW models. Multiple color and profile options allow you to set just the right look and stance for your car. As well as being pleasing to the eye these are very strong and functional wheels that are at home on the street as well as the racetrack. Don't let the price fool you - these wheels are high quality, high strength, and in high demand.

Note: careful consideration of wheel width, offset and tire sizing must be observed when choosing and installing larger wheels. Adding larger wheels may lead to rubbing on suspension components or bodywork. Wheel spacers, new alignment settings, inside fender modifications, or other adjustments may be required.
