33 Differentials

Testimonial - E87 130i - B1 Dynamics Package (Quaife LSD, B1 sport suspension, B1 anti-roll bars) - Mr Wagner

This is the first time I've proactively offered to write an unsollicited testimonial after ordering some parts, but Birds' service exceeded expectations. They were easy and pleasant to do business with and took time to offer helpful advice (Kevin Bird in particular). I have a 130i which I felt could be improved (trouble getting the power down, an unnecessarily stiff ride, somewhat nervous handling and an oversprung rear end).

Hello Kevin,
 
I just want to tell you that I'm really very happy with the diff performance.
 
Driving slowly there is no difference whatsoever unless is slippery, when under mid acceleration you can feel the diff trying to get traction and pulling the car forward without the intervention of the traction control. Amazing!
