Hi Kevin,
 
I had the chance to fit the B1 springs and dampers this week, and I am absolutely delighted with the change. The car feels as it always should have done - still firm, but compliant, properly damped and really surefooted. It’s far more confidence inspiring than the limp dampers that came with the car originally. Thanks for a great bit of kit!
 
Cheers,
 
Mark

Great thanks.

The car is brilliant....a hand full in the wet as my maximum torque is around 2.2k....it seems more twitchy in dtc mode and more in control with traction control completely off....not sure how you run yours??
I feel i could do with a track or skid pan to find some limits really, and my tallent, or lack of it!! Haha

The couple of dry days i have had in it is incredible  and has transformed my car completely, thank you very much.

Team Birds
 
Just to say that this kit is transformational. I am now confidently sideways and loving very much the fact that I have lost none of the compliance of the original suspension. Speed bumps at 55mph now a pleasure!
 
Congratulations on such a well engineered upgrade.
 
With kind regards

Dear Mr Bird

I wish to record my sincere appreciation for your assistance in the matter of exchanging the lsd to my 335.

I am delighted with the suspension, as supplied by your company, which was fitted by Graham Martin. I have been considering changing my car for a M235, but after the recent modifications, I have decided that I have something worthy of retention.

Once again, a big thank you.

Your sincerely

Ken
