i am going to purchase an lsd soon, and i was wondering which is better for a street driven, auto-x car?, clutch or helical?

 

Helical.Better turning traction and control.The only drawback is pricing.

Not really, virtually every FWD Honda race car turns better lap times running a mechanical (clutch type) LSD, plus you have a more direct path to put power to both wheels at the same time. There's a reason companies like ATS, Mugen, and Spoon all run mechanical LSD's.

Most quality mechanical LSD's will cost more than a Quaife, and tons more than something like an OEM ITR unit. A helical LSD will last much longer though.

 

Clutch type I say provides a better performance than helical type like quaife. Quaife is a lot easier to deal with when used for everyday.

Clutch type, be it 1.5way or 2 way is pretty rough when you are taking a turn from a dead stop or low speeds.
