Reminds me of another question. I am considering an electric power steering for my 73 scamp. Any changes to the skosh recommendations for power vs manual steering?
But if you use that for manual steering you might want to reduce those caster numbers depending on your front tire width and if the manual steering ratio is 20:1 or 16:1.
Caster is not as performance enhancing as Camber then Toe. Caster can induce some camber in cornering. The caster is mostly driver feel and high speed stability
