Oh learned team - I am intrigued.
 
In the June issue (Vol 36, No.5) of AHC-USA magazine, there is an
interesting article from Chris Kellner describing the build of 'Annie'
the Red Racer.
 
Within the pictures there is a shot of Eddie Miller bending a steering
arm to "eliminate bump steer".  Now, I had got used to the excitement
generated when pushing hard through the twisties, but never really come
to terms with the unpredictable reactions in the bumpy bits.  I hadn't
considered bump steer, figuring that the handling was a feature of the
steering box or the 'period' suspension.  
 
Is bump steer a real factor in these cars?  Can it be reduced in the way
that Eddie has adopted?  Is it a closely guarded secret held only by
those racers that want to keep an edge, or can the arcane wizardry be
shared in public without shame?
 
Go on - I can take it.
 
Cheers.............AlanB
