What alignment would be ideal for my driving style (daily and canyons and hooning)? Like I know I can’t adjust much as is, but say I could adjust anything then what is the ideal setup for me? Like back to factory specs would be good? How much camber is ideal? Obviously no camber is needed to go straight down the road, and shouldn’t there be some dynamic camber under cornering suspension compression, right? Would a basic alignment place know the stock specs, or do I need to supply that or my wishes? Just looking to be prepared.

Find a place that accepts custom alignments, a lot of places just want to put it on the rack and make sure the numbers are green and make the quick buck.
With lowering you should be able to get -2 degrees front with camber bolts easily enough. Lower control arms in the rear is recommended for adjusting rear camber. I'd say -2F -1.5R is a good starting point but honestly if you can tell a huge difference on the street between -2 degrees and -1 degrees you are probably gonna get your car impounded at some point. I prefer zero toe but a teeny bit of toe in helps stability

This should be pretty good for a ~1” lowered car. Toe is the most important here, you want 0 up front ideally. The steering in this car is precise enough that it won’t be unstable at speed. Camber and Caster will be what it is most likely, it’s not adjustable on this car. They can adjust the front a tiny bit by shifting the strut mounts in the bolt holes, but they likely won’t. Quote:
That’s good! Pressure should be okay then! We do have to keep in mind than the range of acceptable tire pressure is pretty wide. |

Another thing to check is the condition of your shocks. If they're knackered then you can experience some strange wear patterns on the tyre.

UPDATE: I took the car in for the alignment. Here are the results. I am ordering some Michelin Pilot 4S, so I have them ready. I think the toe is part of the problem, but because the left front is so good and the right front is so bad, and the toe seems to be both bad, I can only conclude that perhaps it is just the driving style.
I was explaining to the technician how the left rear kicks out to the left under heavy throttle like 99% of the time, and how I thought it does it less with traction control on, which leads me to believe it is the VSC, and he said that could be the case. I asked how I could have such bad wear on one and good wear on the other, and the technician says in the US we make more right hand turns, which makes sense like I am much more likely to make a power slide on right hand turns from a stop (for fun) than during wider and longer left hand turns. Maybe that could explain some of it. I don't know.

Looks like Toe was all your issues, that plus slightly over inflated tire pressures. 35/38 cold pressures can easily become over-inflation after 15-20mins of highway driving. Old tires are also very sensitive to bad toe/camber and will start wearing unevenly.
I'm still shocked people make suspension changes and think it's ok to drive without an alignment. |

The "before" was not good.

The "chassis to hub/ground height" is irrelevant and not a constant or tangible measurement. Makes sense, most people, like yourself, don't understand how suspensions work. This is why I think there should be more disclaimers everywhere in instruction manuals and DIY's. if you make any change to your suspension geometry you should get an alignment. Best err on the side of caution rather than destroy your tires. $100 is good insurance when spending $500-$800 on tires, not to mention better handling. |

Even though you have very little camber, wear from toe out + neg camber is going to compound. -0.9 deg * half the total toe out is going to cause way more inside edge wear than -0.4 deg * half the total toe out. You might notice some outside edge wear now that your toe is zeroed, but high tire pressures could hide it. Watch it and think about camber bolts if you notice any appearing. |
