"Too bad there isn't a good substitute for the B4 fronts. B3 wheels have radically different dimensions, and Losi fronts are totally different."
On my last B4 I used Losi steering spindles and front wheels. The spindle must be drilled to fit the Associated hingepin and the steering arm is longer which increases ackerman effect. I felt that the car steered more smoothly and could be driven more aggressively off of the corner but running the rear hole on the steering link brings it closer to stock. I'm not sure why I haven't changed my current B4 over.
