Hi Kevin, hope you are well.

"The Quaife diff sits alongside the suspension as a must have for anyone thinking about modifying an M235i or M240i. Not merely because it allows big silly skids, but because it works with the chassis to better deploy the engine's ample reserves. The inconsistency and unpredictability that can come with a powerful RWD car running an open diff is gone, replaced with much more transparent (and enjoyable) relationship between throttle pedal, steering wheel and rear axle. This is what baby BMWs should feel like..."

Hello Team Birds.

Just finally got round to writing a testimonial for you to put up on the website

I’ve waited over a year since I investigated your workshop for you to do the modifications the B2 dynamics package of the Quaife diff and suspension.

For customers with highly modified cars, or who use their cars aggressively, or for those with high mileage cars looking to prolong the life of their differentials, we would recommend our high-performance bearings.

These uprated tapered bearings offer a 44% increase in load capacity compared to the standard BMW ball bearings, providing much improved durability and a longer lifespan.

Hi,
    My review is a bit lengthy, feel free to reduce it.

Kevin,

Only an initial review after a quick 30 minute hack but really, really pleased, transformation gets used a lot but in this case, deserved.  Car is far more settled, not upset by variable road surface which lets you keep the power down.  At the same time the car is a more comfortable place to be, secondary ride is another level.

Hi James,

Video has been released on 'JayEmm on Cars' channel. I thought over the best person for it that would give off a mature view. Since the car has been to you i have also added the M3/M4 LCA and TS also powerflex rear subframe inserts so its a semi frankenstein B2 dynamics setup. Which he covers the whole car in the video as a “review”.  Needless to say he was very impressed with your suspension and adding the quaife and during the filming he definitely mentioned your name.
