More wheelie bar questions

(1/1)

retroboy:
I read lots here about folk hitting their wheelie bars hard and unloading their slicks. When or why did sprung wheelie bars become unfashionable?

dreracecar:
Because racers being a creature of habit, will blindly do what others before them have done without question. I run spring bars. No transbrake, and weight on the front, no gages or tach, and still win races

dusterdave173:
This is a FWIW
I got the wheel and bar kit from N & P  made my wheelie bars unsprung   well for the longest time car would go straight, then not then left then right--I measured a dozen times from the edge of the brake rotor etc  come to find out
the holes I had frilled for sliding bar height adjustment were too sloppy--you could take the wheel and twist it  just a tiny amount either way--Redrilled all the holes so they are a PIA to get pin in and out and whammo--car straight as a laser every pass--NO play at all in the system---I used thin bars on top they give  a little flex--car runs great

retroboy:
Thanks for your thoughts. I'm going to go ahead and fabricate a simple pair of sprung bars as I ran decades ago. Makes more sense to me to have something to absorb any shock rather than transfer it to the chassis and so tyres. Cheers

THE FRENCHTOWN FLYER:
Curious - what are everyone's thoughts are on single-vs-two wheel bars? I've used both and aside from the weight savings of a single (sprung) setup I've had success with both.
