Z1 Street Pro R200 Limited Slip Differential was produced exclusively for all 350Z and G35 manual transmission models. The benefit of the upgrade is not only on acceleration, significant improvements are experienced in corner entry, overall cornering stability & corner exit. This leads to a safer and more controlled driving experience and yields the driver more confidence at the limit.
Z1 Street Pro Differential
The factory differential in many 350Z and G35 manual transmission models is a standard open differential. The biggest flaw with open differentials is their inability to distribute power between both wheels. With an open differential torque is applied equally between both wheels, however in situations where wheel slip occurs (such as rapid acceleration) the slipping wheel will receive almost all torque. This imbalance between the left and right wheel leads to poor cornering stability and poor straight line acceleration, infamously known as the "one wheel peel". The factory upgrade to this is the OE Viscous Limited Slip Differential. While the VLSD is an upgrade from the base open differential, they often wear out over time and despite their ideology of being non-newtonian fluid, the tolerances inside the housing change and fluid leaks out over time. Long story short high operating temps in the differential lead to poor and inconsistent performance with the viscous. Often their performance will become erratic at times behaving like an open differential making the car unpredictable at the limit and ultimately leading to poor performance.
The Z1 Limited Slip Differential (SP) addresses these shortcomings without giving up great street manners. The SP is a helical differential that is a dramatic improvement over open & viscous differentials given its considerably greater ability to distribute torque at both wheels. With its internal gear design, it boasts exemplary street manners and is operationally quiet when compared to clutch type differentials that have a tendency to chatter or clunk when cornering at low speeds because of axle bind. The Z1 SP differential is a helical unit that exhibits no axle bind and provides smooth operation in any circumstance. Because of the internal construction the Z1 SP is low maintenance (only regular fluid service intervals) and ensures exceptional life span with no special fluids or friction modifiers needed. Standard fluid may be used, however Z1 recommends the use of Red Line or Motul differential fluid.
Installation Note
It is VERY IMPORTANT that this installation is done by a competent and experienced driveline shop. Incorrect gear pattern, out of spec back-lash or pre-load will result in accelerated wear, noise, etc.
NOTE: This Limited Slip Differential is only compatible with Manual Class Final Drive Ratios.
If you choose to locate a driveline shop for installation, we recommend purchasing new side bearing and side axle seals. As a convenience, this has been included as an option below. (Different spec side shims may be needed for install - available separately HERE).
