Hi,

Is there a need to reduce the caster when going from power steering to manual steering? It is hard to steer at low speed and I would enjoy it more if it was a little easier.

Thanks,

No, same specs. If you are using radial tires, though, I'd use the Shelby specs.

Actually, yes. The more cast you have, the more the tire wants to return to center. Which sounds like a good thing. But that also means it takes more energy to move it off center. With PS, you can easily use 5-6* of caster, it improves turn in, and makes for a very stable ride. But without the PS, you'll be musceling that car all around town (or the track). You'll be pretty beat up.

I put manual R&P in my '66 coupe (302/C4). With the stock caster, it was a real bear. I changed it a couple of times to see what I'd like, and finally settled on 2.5*. That seemed to give me the best combination of ease of steering and good stability.

My street/track roadster is also manual steering. I use 3.5* on the street. But I decrease that to 2* for the track.
