Designed for the 22 2.0, the Universal Joint (UJ) Driveshafts create less "Bone Bind" or "Driveshaft Lock-Up" allowing for freer rear suspension movement, especially on power. This allows the car to squat more on acceleration, creates more side bite, and is more consistent when throttle inputs vary. This is a valuable setup tuning option for high-grip surfaces or very bumpy surfaces, especially outdoor artificial turf, carpet and some higher bite dirt or clay surfaces.
