I've had a Quaife on my 130i before, good product. Now I have a 135i, and considering upgrading this one also. On thing that I'm wondering about is the stock "LSD-function" on the 135i/335i that works through the brakes, (that functions even when you have the DSC/DTC completely turned off.)
- How does the Quaife unit work together with this function and is there a way to turn it off?
