http://www.rx8club.com/tech-garage-22/rx8-lsd-13501/page2/The LSD in the RX-8 is NOT a worm-gear type torsen LSD.
Mazda calls it a "Super-LSD", its appearance is very close to a normal differential. The Super-LSD however, has friction cones (not plates, or clutches) between the side gears and the differential gear case.
If you are familiar with the operation of a normal differential, you will know that speed differences between the two wheels causes torque to be transferred through the side gears, to the pinion gears, thus allowing you to get around the corner.
This same torque forces the side gears out, towards the differential gear case, and when you get enough torque, the friction cones lock with the differential gear case and you end up with a limited-slip effect.
Obviously, if there is little speed difference between the wheels the cones won't lock and variable axle speeds allow you to get around slow corners.
The spring in the center provides preload, so the thing doesn't rattle (there is probably a more technical explanation, but for us I think this is enough).
This LSD is used in later Miatas, and is primarily designed for improved acceleration and better traction. I am not up to date with the track record of it, but its simple construction leads me to believe it is probably more sturdy than the worm-torsen design, and definitely cheaper to repair!
The Super-LSD is actually classified as a torque-sensing (tor-sen) differential though, just to confuse matters.
I'll let you make your own judgements on whether it is suitable for 'DUHrifting' or not.
Happy camping!
btw ik denk wel dat je bij autocross bij de start met een RX-8 in het nadeel bent ten opzichte van de MR2's omdat deze meer gewicht op de achterwielen hebben en daardoor meer tractie zullen hebben vanuit stilstand eenmaal op snelheid heeft de RX-8 mischien wel weer een betere gewicht verdeling over de wielen en zal beter sturen. Veel succes met je project en als je het diff. uit elkaar hebt/haalt maak dan een paar foto's voor ons mede forum gebruikers.
