Actually I was always significantly faster with my B3 than my B4 ... B4 just doesn't suit some people, not a bad car but not a universal one either

thanks for the replies, why will a b4 layshaft help

The gear is the same size as the B3 but the B3 slipper cant handle the power from the brushless motor when accelarating so using the B4 part you can fit the slipper system as well and give much more control of the slipper and zero burnouts of the clutch pads.

the b4 slipper does work better than the b3 one and is definately something to change if you want to race a b3 now, as welshy says, the single pad b3 slipper cant handle the power like the 2 pad b4 one can. in the end though it is all down to how you like your car, if you like it edgy and responsive you want a b4, if you like it comfortable and predictable then the b3 will work for you. my home done mid engine b4 handles very much like the b3, but with lots more overall grip which is a good result for me

Any idea who it was?? I expect a lot of us will know him!
