I have an 05 base with some minor mods done. Eibach lowering springs, and fully adjustable front and rear suspension. The issue I am having is im eating the inside of both back tires at a phenomenal rate. Every tire shop ive been too just tells me its just how the 350z's are... but it was never this bad before the lowering... i do have 18 inch rims from an 2010 and am running 265/40's on the back... i was running a 285/35 and thought that maybe it was just a bit to much tire for the car... but the narrower size did not help... can't the shops simply adjust the camber to compensate for the issue????

 

Have you gone to an alignment shop to get a baseline of what your specs are like?

 

I assume you have had a shop align the car.

Take a picture of the alignment sheet with your smartphone and post that to this thread.

 

If you have the adjustable camber arms and aftermarket toe bolts , it just takes a competent alignment tech to properly align it.

 

It would be interesting seeing the alignment page you get when paying for a wheel alignment,

 

Your toe and camber are probably beyond wacky.

 

Agree, alignment issues there. Have them check toe as that's often overlooked.
