Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Dinan Performance Springs are matched to your BMW's chassis and suspension components to deliver better handling and looks without sacrificing ride quality. Dinan BMW springs are carefully engineered to work within your car's suspension travel and to improve suspension geometry. Spring rates are slightly stiffer than stock and dialed in to reduce bodyroll. A stiffer suspension makes the car more fun to drive and the lower ride height improves the looks by reducing wheel-fender gap.

Dinan spring specs -

• F: -5/8" (16mm)
  
• R: -1/4" (6mm)

Fitment note: Dinan only recommends these springs be used with their custom-valved Koni shocks. While not explicitly required, less than favorable ride quality and handling may result without them.

For over 35 years, Dinan has been America's premier tuning company, pioneering advancements in BMW modification while retaining a focus on balanced performance that preserves the original character and driving feel that a BMW offers. When you install a Dinan part on your car, know that it's not only carefully developed and tested, but that Dinan stands behind it with a four year, 50,000-mile warranty. Dinan believes so fully in their “total package” approach that once your car has been fitted with enough of their parts, they celebrate your conversion from stock to Dinan with an exclusive trunk badge, displayed proudly by BMW enthusiasts everywhere. The springs are worth 2 points towards your Dinan badge.

There are many benefits to installing harnesses in your E46 -

• 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

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 line of 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 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 Tuning harnesses are TUV approved.

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 Harness Summary:

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