Brand new Megan Racing Rear Roll Center Adjuster for the Nissan S13 240SX/Silvia. Megan Racing 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!
