    LSD - Quaife or Wavetrac?

    Contemplating adding a LSD to my 2010 335i - Dinan Stage 2 flash overwhelms the *one* tire. Does anyone have recommendations, preferably based on actual experience? Also, any recommended shops to do the install?

    Thanks, Sam

    Anyone can install a Quaife. Not everyone can assemble a Quaife.
    I have a Quaife and while I like it over the traditional clutch-pack LSD, I found my clutch-pack to be better in wet while the Quaife is better on dry.
    I had a recent discussion with Dan from Diffsonline regarding some locking up I'm experiencing. I just need to use a thinner fluid, but in discussing Quaifes,
    he told me I was leaving some power on the table at the track and I'd be better off with a clutch=pack.
    Maybe someone racers can explain that better?
    Not familiar with a wavetrac.

    Quaifes suck. Lift a wheel, they go open. Get one wheel on a surface that's too slippery, they go open. The plus side is that they are very smooth - that's why they are so good on FWD cars. Quaife/torsen/helical diffs are essentially the same thing.

    Looking at the web site for wavetrac, it's *probably* much better than a standard Quaife. Assuming it's reliable and works as advertised. Of course, it all begs the question of why you aren't looking at clutched diffs as well.

    Exactly my experience. Found that out first hand on the skid pad. Normally tough to break it loose. The next time, Quaife. I whipped it around without even trying.
