Topic: the 9th degree

is 9 degrees too much caster ?   car is a 77 chevy monza  and if i swap the upper control arms side to side thats what the caster ends up being       w/out the swap you cant get much more than a degree as the uppers arent adjustable and the lower adjustment is very limited

Re: the 9th degree

Caster or camber? Are you playing with bump steer?

Re: the 9th degree

No offense; a lot of racers say caster when they mean camber...and lots of racers don't think about caster... I've used over 10 to get camber gain in a pure stock car with rules about static camber....but it had power steering....the jacking effect might make low speed corners heavy if your steering is manual. Can't remember what the geometry is in a Monza but as I recall it's a recirculating ball system. Lots of engine options for a Monza!

Re: the 9th degree

I was thinking along the same lines.  Manual steering, try to keep it under 5 degrees caster.  Maybe 7 if you don't have to deal with a lot of tight turns.

If you have good power steering, I've heard of people running 10 degrees as Jim said.

Personally, I'd leave the caster at 1 degree.  It's a light car, ditch the power steering, and just go for 2-3 degrees of camber.  Should be good enough for Lemons... and no PS to worry about.

Re: the 9th degree

Just like you can have too much camber, you can have too much camber-gain through caster. It depends on bodyroll, your rack ratios, if you have power steering, etc. 9 degrees is probably too much, I've seen about 4-7 on most aggressive vehicles.
