I had a Quaife LSD in an old Civic, and it was amazing. That car was nothing more than a toy I would take out & beat the snot out of, and the LSD was perfect. Until I sold the car to a friend, who managed to blow the tranny up in less than a week
Pro-Tip: When you have 1 drive wheel in dirt, and the other on pavement, don't try to spin the tires. Transmissions don't like that.
Another car I'm familiar with has a Quaife LSD, and is putting down over 500whp to the front wheels. Every track event results in a broken transmission... teeth sheering off gears.
The LSD is still going strong. I believe the owner of that car is about to part it out because he doesn't want to spend $6k on cryo-treated gears : /
I've heard good things about Wavetech products, but have no 1st hand experience.
We have the Carbonetic 1.5 and 2 way diffs on our website, but I'm pretty sure could get you the Quaife as well, since we have them for other cars. PM me with your zip code and I'll shoot you a price with shipping if you're interested.
