Just love it....
I actually wonder if I would have been bummed out with an AMG LSD rear with only 30% lockup as I still squeal the tires off the line (well PS'2s) with 60% lock with Kleemann......but it's a little squealing and the best part is ESP of death rarely comes on anymore.
Only time I have ever heard the famous LSD Klunk was once when going around a 90degree corner such as an intersection and I punched it hard to get into traffic.....one real wheel must have lifted and really tried to spin....contacted Brandon at Klemann and was told it was not that big a deal, but try to avoid.
Here is the response from B man....gosh I love those guys.
This noise is somewhat inherent to the design of the mechanism in the
rear. The mechanism is always applying outward force to the two
planetary gears, the force is determined by the spring pressure in the
clutch mechanism. It is possible to overcome this pressure if the input
into the rear exceeds the clamping pressure. During this time one of
the wheels will slip in relation to the other until the the input force
becomes lower than the clamping force, then, clunk. The clunk comes
from the tolerance in the clutch mechanism and a large axle pin that
passes through it for the smaller planetary gears. I dont think you
have much to worry about- that said, avoid making it happen if
possible.

Yeah, I know that sounded weird. Just a real political way of saying....if you keep doing that s)*&(t, you're gonna roach the gears in the LSD/REAR, but for now, you should be fine.

Yeah, same price Pete...2300$
I am thinking of someday bringing up the gear ratio on the 55 a tick...think that will be best thing I can do to increase performance for the cost.
Don't really give a rat about top end (170-185mph) as I know that would come down....would love to get a little more kick on the low end without hurting the drive train too much. EVO has that right??

New rear runs 3500$...Would be pissed, but not end of the world for me.
If you ask me...the real daredevils are the Nitrous guys....I am in awe of someone with the Kahunas to mess with a 30,000$ motor with something that can be risky like Nitrous...it would be obvious from what I hear, to the techs, if you burnt a piston leading to catastrophic damage....I am all for them modding, but just past my "ball level" at this point.
Sure in awe of them though....maybe someday.
