I was wondering, which lsd do you guys recomend. I don't know much about it and could use some opinions, and mostly facts

Quaife is the best, although a bit pricey. It's worth it, very strong, can hold up to some nasty wheelhop without flinching. Lifetime guarantee.
Phantom Grip and B+M tranny make inserts that make your stock diff a lot like a true LSD, but not quite, plus they ADD stress to the diff, so they're only good for up to about 275 HP and definately are junk if you get any wheelhop.
Kaaz makes a clutch type LDS that's a little cheaper than the Quaife, but I don't have much info on them. Can anyone fill in the gap here?
I've also had some luck getting both front tires to spin evenly by unbalancing the tire pressure. On my car the right tire would spin while the left got traction, so I let some pressure out of the right tires to flatten the contact patch.

Quaife all the way...do it right the 1st time...

I'm currently running the one from Turbotrix (same as bmtranny) $200 and it works pretty well. Haven't tried a hard launch but from a slow roll no spin or torque steer at all. If I break something or if it sucks on the launch I'll be sure to let you know.
