Megan Racing has unveiled our line of reinforced suspension arms that offer the strength and adjustment that any competition vehicle will ever need. Constructed of high-strength steel alloys that offer durability, strength and yet remain light-weight, these control arms have been track tested for months in road race, autocross and drift events to assure quality and performance. Car alignment is absolutely crucial when modifying your car. Alignment can effect every aspect of your driving experience, from straight line stability, understeer, oversteer, 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. These Roll-Center adapters are installed to correct suspension geometry after a car has been lowered. The uneven length of suspension arms causes Toe adjustments to occur drastically during braking suspension "squat", these Roll-Center Adjusters make up for the travel in the suspension arms to return suspension geometry to it's correct starting point. This allows alignment and steering to remain more consistent and predictable during aggressive driving and competition. NOTE: Due to the complexity of the installation, professional installation is REQUIRED! Application: Honda S2000 AP1/AP2 2000-2009
