KAAZ Supra GA70 / MA70 / JZA70 - Soarer MZ20/21 / GZ20 -Lexus IS300 1.5 Way
A 1.5-way limited-slip differential is the most common LSD upgrade option in performance and race cars. It is referred to as a 1.5-way because it functions under acceleration and to a lesser extent under deceleration. It provides differential locking characteristics under acceleration, maximizing power distribution to the wheels that need it most. Under deceleration, the 1.5-way LSD engages to assist in braking stability and smoother turn-in.
Specification:
- 16 Plates for medium to high power levels
- 1.5 way
- Rear Differential
- Fits cars equipped with or without factory LSD option
Factory Differentials vs Kaaz
Most factory differentials are open, which means power is sent to the wheel that has the least resistance. It allows the wheels to turn at different rates such as in a turn, but it is also inefficient in power delivery. It causes single-wheel burnouts when you launch and unwanted wheel spin when you accelerate out of a corner.
Some manufactures equip certain vehicles with viscous differentials. This is a type of limited-slip differential, intended to offer the benefits of an open differential but without the drawbacks of unwanted wheel spin. This is achieved by a series of plates separated by a viscous fluid, which work together to optimize the power distribution sent to the wheels. Although this is more beneficial to performance than an open unit, a viscous limited-slip differential cannot know where to send the power until a wheel starts slipping. Most factory offerings in this case are sloppier than a performance-oriented limited-slip differential.
Kaaz limited-slip differentials solve the problems associated with factory equipment. Kaaz products are built and tuned to deliver higher strength, more traction, and greater stability. The result is quicker lap times and improved handling characteristics with the car under your control in a performance setting.
