Anyone...experience of those aftermarket LSD's

Doesn't it mess up the ETS or any other system that is end of computer..

For example, KLEEMANN’s Limited Slip Differential....?

I don't know about the kleemann but from what I understand it is not a real LSD. I have the Quaife unit and it makes a big difference with traction from start as well as on corner exit. I have had no issues as far as lights or ETS.

Ok, thanks
Was that Quaife unit expensive...?

I an in the UK i think it cost me around 2,000 USD installed

I'm here in Finland, i could install it alone. Where you bought yours..

www.birdsauto.com if I remember the guys name is Kevin he is very helpful.

That is very helpful link, thanks again

I just had the Quaife LSD installed last Friday. no computer issues at all. the esp button still works to put the nannies under a little bit of control. the unit works amazingly. I actually have traction now.

I ask them the LSD to my CL with installation kit and it was 2,121 USD to ship in Finland, and i have to install it myself ?

I may have got the numbers wrong but I think the unit was about 1200 pounds then install on top but I don't remember what the install was.

Yes they say it's 1200 pounds........+20% vat

Not sure you have to pay the vat if you are exporting it.
