lowered my car back in 2004 with tanabe springs 1.5" front and 1.0" rear...front tires would wear pretty often..no issues in the rear..installed front spc camber kit back in 2009 and the tires are still going bald on the insides but not as fast as before...

after i installed the camber kit i got it aligned by a performance shop who worked on lowered 350z's and g35's with camber kits before...

so what gives !?!?! could there be something else wrong with my suspension?? any help would be appreciated. thanks

 

Possibly tie rods..get back on the rack and have your toe checked out

 

yup..im sure your toe is out of spec like jae said

 

+1 I have to agree..

 

+1 for toe. Willing to bet that that is the culprit.

 

IMO, even with a good alignment, factory specs are a bit broad, with too much toe for good tire wear. Check your alignment, and have them reduce toe a bit more next time. It could be the camber as well.

Beyond that, be sure to get your alignment checked every now and then, not just when you replace the tires.

 

Alignment shops don't usually touch aftermarket adjustments. It's possible they didn't touch it.

it's also a pita to adjust those SPC arms without disassembling parts. Alligment shops don't normally remove tires to make adjustments even, and that is the Minimum that's necessary to adjust those SPC arms.

Where's your Alligment printout? Is it actually in spec?

It's possible you have a bad component that's causing new issues, but I'd be more likely to suspect that it was never set properly.

 

You can also set caster with SPC front a-arms. Make sure that is checked when you get your toe settings looked at. I've always set the caster settings to zero on the SPC arm when I've installed them so caster will remain what it is from factory.

 

^Realllly? How you do that

 

There is a washer on the top of the ball joint that can be adjusted to give the desired caster settings. You have to disassemble the ball joint to adjust it though.

 

Fast forward to 2:00 in this video and you'll see what part is used to set caster/camber. It's in the same spot/same bolt. The ball joint underneath has an offset threaded bolt on top where the large flat nut threads into. You'll notice if you losen it up that the lower part pivots the arm forward and back. That is what sets your caster. Camber just slides in and out.

Hopefully that makes any sense lol. I can try to find pics etc if needed.

You can also adjust camber without having to remove the wheel on the SPC (I think you can on all aftermarket a-arms IIRC). Just need a big ole 27mm wrench

Are the shims installed as well?

 

ill post the alignment print out later tonight...i just installed the arms..didnt install the extra little parts that it came with..most people said i wouldnt need to.

 

Those shims allow for more positive camber adjustment. A 1.5" drop is iffy but we'll know once you post the sheet.
