(For the critics street/track is not the same as track/street which is more aggressive than the first)


Thoughts on my story above?
You can select whatever gearing you want. The higher the gearing the more acceleration, but you lose top end speed. As for the clucth LSD you get real lock up of the wheels that holds through cornering.

You have to determine the right mix of gearing, agressiveness of lock-up when it comes to street/track. But that is really the driver decision as many people have different tolerance for NVH. Clucth LSDs are known to chatter and pop and they vary in how progressive they lock-up. All part of the action of the clutches.

I like the OS cause you can set the LSD to 1 way, 1.5 or 2.0, (2.0 would be straight track). You can also customize the angles and ramp up rates between the clutches changes how progressive the lock up rate, but that needs to be done by a speciality shop (Dan -diffsonline, are great shop here in North East)

Have a look at this link too, its a good read.
