Best performance alignment settings?

What’s the optimal performance alignment settings—toe, caster, camber? Stock wheels, tires.

Depends on what kind of performance you're looking for, what type of driver you are, how you like your car, so you can extract the most performance. If you like a stable car at high speed, you want slight toe in at the rear. If you want a more lively rear end, neutral. Same goes at the front. If you want a very darty but quick steering response, toe out. If not, neutral toe. Camber is for high speed cornering on long sweeping turns. It's so that when the car is leaning on one side while cornering, the outside tire gets pushed all the way onto the road, but high amounts of camber reduces braking because not all of the tire touches the road during straight line driving.

So for a street driven car, I'd do maybe -1 to -2 degrees of camber (if it'seven adjustable), 0 toe front and rear, maximum caster. Then adjust from there on how it feels. Just remember, more toe you add, the faster your tires wear. Camber makes them wear uneven, not faster.

I'm getting an alignment next week, interested to hear what everyone recommends on this. I have read some people preferring a little toe in on the rear to make the rear end feel more stable. Danny that's only for high speeds it aids stability? Also, do you have an alignment shop you recommend in NE Ohio?

Toyota in Bedford. On Rockside road. Ask for Mike Hawkins. Does all my performance alignments.
You'll notice alignment settings more as you go faster. Driving around town won't matter much. At highway speeds and beyond you'll start to feel if the car feels stable or not.

I’m getting my alignment tomorrow, any other thoughts/opinions or real life changes people have made? I don’t love how the rear end gets that nervous feeling when pushed hard (similar to what's described here: https://www.supramkv.com/threads/rear-end-wiggle.2388/). Wondering if a little toe in on the rear wouldn’t be a bad idea.

I’m going to try Brunswick Toyota and see how it goes. I hit a curb so they had to order a strut for me ugggghhh. Here’s what mine looks like now (R for red, meaning out of alignment). Rear end is essentially 0 toe.. there are some people who reported their rear toe settings were off from factory (https://www.thedrive.com/news/31031/is-the-2020-toyota-supra-broken-straight-from-the-factory). Not so with mine

Now that I’m looking at it more closely - it looks like my rear is actually toed OUT stock, and that is considered in the normal range of 0.01 to 0.11 inches. How much difference does a couple millimeters make with an alignment?

positive toe is “toe in”

as for the other question, youre asking what difference mm’s make in a precision environment aka alignment.

Thanks.. just wanted to make sure I shouldn’t expect anything except perfect symmetry. And thanks for clarification on toe

So sounds like my stock rear alignment could have been a reason for the rear end nervousness

It's possible but I don't think anyone knows for sure. I'm still waiting on delivery of my 2021 so I can't speak from personal experience.

From what I've read, I don't think there's a definitive answer as to what's causing the nervousness. It's all been thrown out there over the last few months: from bump steer (https://www.supramkv.com/threads/toyota-supra-ruined-by-bump-steer.5377/page-3#post-89151), bad factory alignments, e-diff issues, traction control (rear brakes activating), or just an under-sprung rear triggering all of the above. I'm curious to find out!

Tech wouldn’t talk to me about alignment settings beforehand, just told the sales rep to tell me he can only put it to factory settings. Overall, it’s fine. The readout is confusing on toe - they assured me that the rear is toed IN .12 degrees and front is toed OUT 0.04 degrees, but neither of them are negative values. Can anyone confirm?

Also annoyed camber and caster aren’t perfectly symmetrical. I’ll go to a performance alignment shop next year when I get wheels/tires/suspension upgrades. Hopefully it will be a better experience

Toe in (edit) on both.

.1 of a degree difference you're not gonna notice at all. It's actually really good to be that close, considering camber isn't adjustable on the Supra if i recall. Rear toe seems to be exactly where it should be according to it's dead center position so it should be fine.

You’re sure it’s toed out in the rear? They definitely told me it was toed IN on the rear. And according to this post https://www.supramkv.com/threads/2020-supra-documents-added-to-tis.1915/ (go to last bullet point), normal values for rear are toe in as well.

Just Googled it. You're right, it is toe in.

Leave it to these jerks to make camber in negative, but toe in positive

Because making everything the same would be too easy right??

Edited my previous comment.

Front camber is not truly adjustable stock without camber plates (rear is). If you're looking for gains, consider lowering springs. Refer to Art of Attack's thread to see ballpark gains from springs: https://www.supramkv.com/threads/art-of-attack-mk5-track-build.2324/page-2
Toe can be negative. Positive toe is toe in, negative is toe out.
If you're looking for a baseline track performance alignment, consider this thread: https://www.supramkv.com/threads/track-alignment.2951/
If you're after the perfect track alignment (track dependent), you will need consistency and a pyrometer. Outer / Middle / Inner temps will tell you all you need to know.
Don't use a dealer if you're after custom specs or want to be fed anything but bullshit
Please dont run 0 toe on the rear of a car with this amount of hp (as I read in an earlier post) unless you truly know what you're doing.

Ugh I’m confused now. Does that mean my front is toed in? They told me it was toed out in front, but the value for both from and rear is positive :what:
