I plan to get a good LSD on my DD 335i(I drive very aggressively on the street and the lack of traction from LSD-less BMW is killing me).
There are many threads on clunking issues with the Wavetrac, but not everyone posted what the real problem was and the solution. It didn't seem like it was a setup issues at all. Was it something internal, QC or design flaw with the Wavetrac?
I would rather have something that will work right the first time and not have to worry about it down the road. So far I am leaning towards the Quaife.
Manufacturing flaw with some batches. I don't know the specifics but I think it's a crapshoot. I lost. Thankfully I had a great shop to back me up.
I wouldn't say they are the best shop in the world. But from my experience, they do back their products with excellent customer service.
