Alignment specs for spirited DD

[Nate_V8]

Toe in is a stable condition. Toe out, somewhere between less so and unstable. You want the rear to be stable rather than anxious to steer off in some other direction at least partly because you don't have direct steering control over the rear wheels.

So then why am I going to be setting 0.10-0.12 toe out in the rear? Shouldn't I be running toe in then?

Was going to use these tomorrow

Front
Camber: stock
Toe: as close to 0, same both sides

Rear
Camber: -1.4 to -1.6
Toe: 0.10 to 0.12 per side, thrust angle 0.00

Positive is toe in

I had over 2 degrees of negative camber and a good amount of toe out at one point in the front of my old 2012 Mustang. The steering was razor sharp and quick, but my tires wore out a lot faster so I would not recommend going any more out than 0 for a street car. As for my current car, I'm running factory toe specs front and rear and have about 2.0 degrees negative camber front and 2.3 negative rear (I'm also lowered about 1.5"). Handles much better than stock on the same wheel/tire setup, wish I had more responsive steering though but I don't miss the tire wear on a street car. Tire wear is fine. Car still hooks up at the drag strip too so it's a good compromise.

Would probably perform even better if you lowered the rear camber to -1.5. No reason to exceed -2 on the Mustang rear suspension. Not even track guys go more than that.

Well looks good now, that one front tire though was unexpected

 

[Nate_V8]

Looks good...just so little front camber!

Until next spring when I do the full suspension

 

[AlbertD]

I agree looks great!

@Brian@BMVK, what should the optimum street/spirited driving all-stock suspension alignment settings be? Is this acceptable or even possible with stock suspension parts?:

Front: -1.3 degree camber
Zero toe
Zero steer ahead
Rear: -1.2 degree camber
+0.12 toe (toe in)
Zero thrust angle

How spirited is your normal street driving? About like every other commuter/errand-runner? Can't resist rising to the challenge of a curve or corner? Somewhere in the middle?

It’s not an SCCA vehicle, but I do have some great curves during my commute.

Given that you can't adjust the front, pretty good. Is that 0.12 toe in on either side or total?

Shouldn’t the rear toe-in be 0.12 on each side?

Not being an "SCCA vehicle" would not exclude it from benefitting from Ford's own factory shop manual procedure for providing camber adjustability.

Does anybody have the stock alignment specs for 2019 Bullitts? Curious about that. I took it to the twisties right after buying it (to about 0.80Gs, due to new tires and 60F temp), and it was better than I expected for such a heavy beast. Zero hiccups, and no protest from the tires, but wasn't pushing it that hard either. Just slight (and expected) understeer, but easily dialed out with the throttle. It was fun. So probably not going to change anything, but want to know how aggressive it is from the factory. Thank you.
