ALIGNMENT ISSUES. /// HELP

[quinfalls]

I have a 2021 GR and have been having camber issues. The shop I take it to has said everything is in spec as per their machine BUT I have owned the car since May 5th 2024 and have gone through three sets of tires…crying…

Has anyone else had this issue? How did you fix it? I don’t do burnouts or anything crazy…a pull here and there but not so much that I’d burn off 3 sets of tires I’d like to think.

It was lowered by the previous owner. It always seems to wear on the inner edge on the rear even though it is “in spec” any help would be appreciated as my wallet is suffering buying tires every 5-6 months.

I can post the sheet from their machine tomorrow morning if that helps.

Would help how much miles you drive per set

It has already been explained a few times in this forum. If you have quick wear on the inner edge toe is the biggest culprit, not camber.
In the front you can run zero toe or just a bit of toe in.
In the rear you need a bit of toe in, 0.10deg per side is fine, but I don't understand the total toe on your sheet.

Rear camber and toe look fine. If anything, they are on the more conservative side so they should be wearing slower than everyone else.

What is your mileage per year?

Toe. If that is the print out they gave you and you still get inner wear then they might not have let the car settle when doing adjustments. Then your alignment would be off compared to the sheet once settled. Or they didn't torque down the eccentric bolts well, or they are worn out, and have slipped.

Around 6000km per set on Michelin pilot sport 4S’s

My thoughts as-well, if it was the 0.10 toe on either side the total toe would be 0.20 I’m trying to find another shop that works on these cars for hopefully a better understanding

Per year about 20,000km (Canadian) on Michelin pilot sport 4S’s

I will be taking it to a different shop more suited for these cars. I’ll tell them what you said and go from there. Thanks!

I have very similar geometry settings and have done 6k this year with plenty of tyre left. I am not convinced that the read out is true and accurate.

0.10 toe-in is not enough to wear tire that fast, toe-out would accelerate tire wear but im still not sure if it would wear that fast. It is possible their machine isn't well calibrated, try another shop maybe. -2.5 camber is also not a problem on the front, im at -3 and 0.05 toe-in per side and my front winter tires barely wore over 7000km
