Thanks James. It’s fantastic. The best mod I’ve ever bought for a car.
I mainly wanted it to make slides easier to handle, but the overall increase in traction on windy, wet roads is amazing.
Regards
Mark

BMW’s M135i has received many positive reviews for its fabulous straight-line performance, its improved ride and handling, and its incredible on-paper value for money. The BMW experts at Birds completely agree, and believe that it’s very nearly a true M-Power BMW... Nearly.

Dear Mr James,

I've put 700kms on the diff now, and it's performing brilliantly! The increase in traction on slippery surfaces is fenomenal, far greater than I expected. With the exception of one squished belleville washer Arctic Trucks did a fine job installing it, so if you get any other customers from the Oslo region you could always recommend Arctic Trucks as an installer :)

Hi Kevin,
It’s just ... great!
Initially when you first drive off the changes seem very subtle but within 20 minutes or so…. and some familiar stretches of road it really hits you how different things are …..When pushing on, the car now just inspires confidence ....the steering seems much more responsive especially when quick inputs are required.

I will try to call tomorrow (Wednesday) about 5 PM to give you my Switch details. The parts arrived at Simon Graeme’s yesterday and I collected them today. Thank you very much.
