33 Differentials

Testimonial - Quaife LSD - F20 M140i - Mr Palmes

Kevin,

Loving the quaife already! It feels so much better, so much more predicable when the back breaks away. 

I used drive with the Dynamic Stability Control on the Sport+ setting before, because the car didn’t give me enough confidence with it turned completely off. But now I have it turned off all the time, and drives much better for it.

Thanks again

Mr Palmes

Testimonial - Quaife LSD - F32 440i - Mr Smith

Kevin,

Just a quick note to say that I’m very happy with the mods you made to my 440 today.  The gear change has improved immeasurably - shifts are shorter and the feel is much more mechanical.  I adapted to the heavier clutch almost immediately.  The LSD appears to have given the car much better traction on bumpy roads - it drives out of corners better and is more confidence inspiring.  Overall, I’m very pleased - thank you to you and your team for achieving this improvement.

Editorial - F20 M135i - Birds B1 review and M2 comparison - Autocar - March 2018

"Our M135i out-punches the M2 by 25bhp and 51lb ft of torque, so it feels stronger through the mid-range and more urgent near the redline. But with less power to deploy to the road, and wider tyres with which to do it, the M2 does have better traction..."

Kevin

Just a quick note to thank you and your staff for the work done on the car, it does indeed feel a different vehicle, the crashing about over bumps and jumping around has disappeared, the engine throttle response is much improved as is the power.

I got back here last night around 10.15pm, hoping I have not triggered any bloody speed cameras.

All being well I will return the car to you early on the 9th March for the brakes, if its ok I will wait while they are done, I can always go for a walk to pass the time.
