Wheel alignment is absolutely crucial when modifying your car. Alignment can effect every aspect of your driving experience, from straight line stability, under-steer, over-steer, acceleration, braking and tire wear. Although stock components allow slight alignments from the stock suspension settings, they often are not able to properly align the car after the suspension has been modified. From the factory, most cars are set to have under-steer and for optimum tire wear at stock height; under-steer is often undesired from a performance standpoint but is always dependent on driver style, therefore the adjust-ability of the alignment of a vehicle is critical when tuning for speed. The clock does not lie and having the vehicle alignment can make seconds of a difference. Megan Racing Inc. has developed reinforced and adjustable control arms to accommodate the needs of the aggressive and performance oriented tuner. Being constructed of a Lightweight Steel-Alloy which is able to withstand the stresses of extreme competition, these arms are powder-coated with a 3-Stage process to ensure durability and protection against the elements. These Rear Arms are adjustable to fine tune your cars handling in the rear. When lowering a car, these will eliminate premature tire wear caused by the rear wheels riding upon the inside tread only. Combine with Rear Toe Arms and Rear-Rear Control Arms for the ultimate in adjust-ability. Alignment is crucial to the handling of your vehicle.
