Alignment is obviously off and no one seems to know why

Big worm

So a backstory first. I have a 370z touring non sport. Previous owner added the 19" rays wheels. Since ive owned the car, ive added H&R sport springs and got an alignment right after. Few months after that, I added H&R wheel spacers, 20mm in back and 15mm in front. Didnt get an alignment because i thought spacers didnt affect that. Wrong, my rear tires were balding very badly on the inside so i got another alignment. The problem kept happening, so i took off only my rear spacers and left on the front ones.

Currently, now i only have front spacers and the lowering springs, and i noticed my front tires are balding like crazy once again. I dont want to have to remove my lowering springs or spacers. I dont even know if thats the problem. But its like the alignments arent really doing anything. Help! What do i do now?

Pic of my front tire attached.

What were the numbers on the alignments? Were they able to get back into factory specs?

i wouldnt know, how would i find that out? Im wondering if theyre getting it to the specs of my z with its stock 18" wheels rather than my replacement 19s

Because they should have given you a sheet with all of the numbers on it. I'll go ahead and tell you your camber is off. You most likely need front and rear camber arms. The factory arms have almost no adjustment in them. Might as well do toe bolts too. If you lower these cars, you'll need camber arms 99% of the time.

your alignment is off. because you have H&R Springs.

H&R is a nice low look, but crappy ride, bad for your OEM shocks and doesnt help your tires. I had a friend with H&R and he went through his rear tires in under 5k miles

You will need to:
1. Remove Springs
2. Add front/rear camber arms

suggestion:
1. Remove springs and go to coilovers or swift springs and add front/rear camber arms.

Is there a reason he won't be able to get the alignment back in spec with camber arms and toe bolts if he keeps the springs?

Ugh, another money pit. Thanks for your help though. I definitely know its the camber but i thought the alignment shops would have told me something if i needed the camber arms... guess theyre fine with just taking my money and telling me to have a nice day.

Big worm

curious as well. why get coilovers and arms/bolts if i would just need arms/bolts

Chuck33079

On the upside, camber arms aren't that expensive compared to tires.

sorry for the confusion.

option 1 and 2 are exclusive.

meaning he can remove them OR get camber arms

with the camber arms , he can get back in spec no problem.
But i would still worry about the bouncy ride / shocks

Chuck33079

Ah. Cool, that's what I thought.

Big worm

yeah, but now im looking at close to a grand just to get my car at a normal alignment. The tires need replacing anyway. i now have to get tires, camber arms, and an alignment. UGH just UGHHHH

Big worm

to hell with these springs. thanks all...

It's very well known here that you have to do camber arms when you lower the car. It's part of the deal. It's not that big of a deal. They're fairly easy to install.

Always have to consider things when changing something.

somethings are harder learned, and I think everyone here has gone through that lol.

Keep the spacers, remove the springs.

look in the for sale section, you can find camber arms and coil overs constantly at times. take your time buying and then when you have the right sets, put it on together.
