increased caster and control arm options
I just completed swapping out the original power steering on my 63 Impala with a intergral Borgeson unit. I am about 90% happy with the outcome. The 10% remaining is a little 'wandering' and some slight highway speed vibration.
The instructions that came with the new unit recommended 3-4 degrees positive caster. With my stock control arms I could only get a little over 1 1/2 degrees. I think if I could achieve the recommended value, the remaining issues would be resolved.
To get to the minimum recommended caster, I believe I have to install different upper control arms. I've seen fancy tubular arms from Hotchkis and Global West that advertise upwards of 5-7 degrees but they are expensive.
Are there any 'stock' like control arms available that are less costly and would work?
Also, I am new to this front end 'science' and please set me straight if my analysis is off base. My car is stock hight and I am running p215x70r 15" tires/wheels.
Thanks in advance for any comments/replies.
