Caster and Camber

[RR Fan Dan]

I know the b bodies like positive caster. From my understanding on another thread the 73/74 control arm set up allowed more caster than previous years which was an improvement. Most people are achieving between -3 to -4 degrees of castor. Is there a point where there is too much negative castor? In your experience, what's the ideal setting for caster and camber in a daily driver street car? Not for drag racing or road racing. What should I be looking to achieve on my 74RR.

More negative caster steers easier but, tends to wander at speed. Too much, steers hard at low speed but, steadies that wheel at speed. We must have specs here in previous threads.

I did a search and didn’t really find anything. I’m also not looking for FSM settings, I’m looking for settings based on user experience of works best.

You want positive caster and any camber would be negative. 74 RR should be power steering right? 0 or neg caster would be for manual steering cars.

Alignment tech is going to have to tell you what they can get out of it. Caster +3-5*, adjust side to side for road crown, Camber -.5’ish*. 1/8” total toe.

Thanks that was what I was looking for. It is power steering. Is there anything as too much caster. I’m assuming you can’t get there in these cars.

With excessive castor as the steering wheel is rotated the front of the car is raising and lowering.

Adding positive caster lowers the attachment point of the outer tie rod. If the outer tie rod is lowered it will eventually cause bump steer. 2-3 degrees positive is plenty of caster. Run the camber -1/2 to 0 unless you are trying to autocross or do trackdays.
