Dear James,
I just got the pumpkin installed today. Great difference! I can feel less power is wasted, quicker acceleration. Now the car has more traction, connering at high speed in sport+ is even more safe now (albeit the open diff was very hard to get oversteer at the beginning).
My garage man were impressed by the product, may I ask for the technical specification of my LSD? So that he could consider it himself and do some advertisement.
Best regards,
Charles
The popular QUAIFE ATB Limited-Slip Differential is now available and in stock for the F20 M140i, F22 M240i, F30 340i and F32 440i, exclusively at BIRDS.

Kevin
If not too late can I have the old suspension parts (not for me but when I eventually sell on they would be good to have)
Really pleased with the work
