Recommended Alignment Specs?

Recommended Alignment Specs? - 06/15/21 06:25 PM


I'm getting my 71 Sebring aligned after installing the Borgeson box. It's been a while and I lost my notes on what a good street handling car should use for specs. Does anyone have recommendations for the caster, camber, and toe? I run 255/45's all around and have the Hotchkis uppers.

Thanks.

0 camber, 3 positive caster, total toe 1/8.

I agree.
A better handling car needs some amount of negative camber.

I run 1.5 degrees negative camber, 2.5 positive caster, and 1/16 to 3/32 toe in on my handling oriented mopars and my lemons valiant. For track only use the lemons car needs a touch more camber as I wear the outer edge faster.

Yeah, for road course use I've run 1.5-3.0 neg camber; but street, 1.0 is about max, except 2nd-gen GM F-bodies, mine liked 1.5-2.0.
The Drag Race chart caster seems odd - my Duster runs triple that, and goes straight as a string.
But you don't want your hand in between the steering wheel spokes when it unwinds in the staging lanes.

I ran around 3-4* positive caster in my drag cars and set these specs up with 1" of suspension rise in the front. Ran straight and solid at triple digit speeds. Had much higher steering effort, but with 4" wide tires, it wasn't much concern.

The more body roll a handling car has, the more negative camber it may need to keep the tire upright. Softer spring rates will typically require higher camber numbers than stiffer spring rates.
