Megan Racing has unveiled our line of suspension components that offer the strength and adjustment that any competition vehicle will ever need. Constructed of forged aluminium that offer durability, strength and yet remain light-weight, these roll center adjusters have been track tested for months in road race, autocross events to assure quality and performance. Unlike other design that causes slippage and unnecessary movement, these solid offset RCA ensure front alignment stays constant. 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 (installed together with the optional plates) 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. *MRS-HA-1550 is used for adding additional negative camber (negative 2-3 degree, up to -3.5 degree adjustment) for S2000 front camber. - Extra thin piece is an optional adjustable piece (use depending on ride height for example). It can be added along for vehicles that are much lower for extra roll center adjustment. - For extensive track usage, please use aluminium or heat wrap on rubber covered ball joints for prolonging life on these parts. Application: Honda S2000 AP1/AP2 2000-2009
