A staggered fitment is also referred to as a staggered application. Basically it means that you are running different sized wheels on the back of your BMW than from the front. Usually a staggered wheel fitment refers to wider wheels on the rear of the vehicle, for example 19x8.5 on the front and 19x9.5 on the rear. Running wider wheels on the drive wheels means more grip on acceleration and from an aesthetic perspective, it means larger lips.
Handling can be improved by running larger wheels. Larger wheels mean you will run a low profile tire, and usually, a wider tire. A low profile tire often performs better when cornering and braking, as tire roll is greatly reduced. A low profile tire will result in a stiffer ride. Extremely large wheels are heavier and can increase braking distances. However, Beyern will always endeavor to keep the wheels as light as possible without compromising the strength of the wheel.
With regular care and regular road conditions, Beyern offers a two year finish warranty on its wheels with chrome and painted finishes. Beyern provides a five year structural warranty for wheels it manufactures that are structurally unsound because of a manufacturing defect caused by Beyern that makes the wheel unfit for its ordinary purpose. Damage or issues with wheels manufactured by Beyern that are not caused by, or the result of, a manufacturing defect by Beyern are not covered under the warranty. Additionally, the following are expressly excluded from the warranty:
• Beyern does not offer a "road hazard warranty," so any damage or issue with a wheel caused by the wheel colliding with a pothole or any other object or debris will not be covered by the warranty;
• Wheels that have been used in racing are not covered by the warranty regardless of the damage or structural unsoundness; and
• Wheels mounted on vehicles with a load rating in excess of the load rating of the wheel are not covered by the warranty regardless of the damage or structural unsoundness.
• Wheels that have been modified, repainted, or powder coated.
THE WARRANTY ONLY APPLIES TO THE ORIGINAL PURCHASER OF A WHEEL AND THE WARRANTY IS LIMITED TO THE ACTUAL AMOUNT Beyern WAS PAID FOR THE WHEEL.
To submit a wheel for determination of coverage, a distributor must first obtain a Returned Goods Authorization number from an authorized Beyern salesperson. Wheels sent to Beyern without first obtaining a Returned Goods Authorization number will be refused and returned to sender. After obtaining the Returned Good Authorization number, THE DISTRIBUTOR WHO PURCHASED THE WHEEL FROM Beyern must send the wheel by freight prepaid, as freight costs, shipping costs and any consequential damages are not covered by the warranty, to Beyern headquarters in Huntington Beach, California for inspection by Beyern. The invoice of the original purchase must be included with the wheel so Beyern can verify the wheel is being submitted for coverage under the warranty by the original purchaser. A customer of a distributor cannot directly send a wheel for inspection to Beyern as Beyern does not communicate, correspond or deal in any way with the customers of Beyern's distributors. A wheel submitted to Beyern by a customer of the distributor will be returned. After receiving a wheel submitted by a distributor for inspection, Beyern will inspect the wheel and notify the distributor if the wheel is covered by the warranty. If Beyern determines the wheel is covered by the warranty, Beyern will issue a credit note to the distributor for the amount the distributor paid Beyern for the wheel.
The Beyern Spartan Wheel is manufactured using a highly advanced production technique called Rotary Forged® Wheels /RF™ Wheels. The rim of the wheel is forged at high pressure while the wheel is spun at high speed. This alters the molecular structure and enhances the strength of the alloy. The benefit is a much lighter weight than a regular cast wheel. Most importantly, the weight saving is in the outer rim of the wheel which dramatically reduces rotational mass and enhances vehicle performance.
Some wheel designs are enhanced utilizing a CNC Milling technique. CNC (computer numerical control) milling machines are used to perform complex drilling and contouring operations to enhance the design of these wheels. Take a look at closeup image of these wheels (click on any wheel image) and notice the milling grooves that flank the spokes and central contours of this wheel, giving it a machined artisanal look
