*The 1.5 Way LSD (shown above) is ideal for road racing because under deceleration the diff does not lock up as aggressively, allowing for more control and traction going into turns. The 2 Way LSD (shown below) is ideal for drifting because under deceleration the diff does lock up, allowing for better control when sliding. Kaaz diffs are known for their consistancy and quality. Kaaz LSDs are considered to be far superior to stock LSDs and are widely used in racing and drifting circuits. Driving styles differ greatly. This is a general definition; there are certainly instances where these definitions will cross over. **Note- If you have an 89-92 RX7, please let us know if your original diff was open or Limited Slip. ***WPC is a coating applied to the LSD to allow for less noise when turning. If you will be using this LSD in a street car and would prefer not be noticed every time you turn, it is recommended that you get WPC coating. However, if you do not mind a loud "banging" noise when turning, WPC coating is not needed. |

| Kaaz recommends using ONLY their gear oil in their LSDs. Using synthetic oil will destroy your diff. | ||

| 93-95 Twin Turbo | 27-200E-P099 | |
| These very unique torque
sensing differential limited slip units are now available for 84 and later
RX-7's. They really are the absolute best design for rear traction under ALL
different conditions. It is able to transmit far more torque to the wheel that
still has traction than any other type of differential. It uses the friction of
the worm gear teeth and the thrust washers for the differential limiting force.
In comparison with viscous type, or friction type LSD, it has the following
benefits: 1) Large bias ratio torque proportioning 2) Less change of bias ratio over time of car use 3) No special differential oil or LSD additives needed 4) Improved overall traction and improved controllability under acceleration. 5) Virtually no change of torque sensing or traction control through differential temperature range. *Note- if you have an 86-92 Non-Turbo rear end we KNOW that 86-88 N/A stub axles will work. We also KNOW that 89-92 LSD stub axles will NOT work. If you have 89-92 Non-LSD stub axles, we do NOT know that htey will work with this diff. Some measuring will be necessary. |
