I hope somebody can help me out. This problem has been creeping up on me as I have been lowered quite a bit for ~25k miles.

I got an alignment about 5k ago, I don't have the sheet with me but I will recall it the best I can.

Front - Camber -2.1 -2.0
Toe- Slightly Positive (Toe in)
Caster - Nothing crazy but definitely a decent differential between the two sides (.5?) Sorry I can't remember exactly.

Anyway here is my front tire.



Clearly, I need new tires asap, but here is my problem. From my understanding this would be caused by toe out. I am quite sure that my compression rod bushings are shot, they seem to be slightly torn from what I can see. But, wouldn't that cause the car to pull? This is not the case. My car drives pretty straight on the highway.

I plan to get the SPL Compression Bushings anyway because I know it is time, but is there anything else I am missing here? I am worried I am going to install this and not solve my problem.

Thanks to any help.

 

I hate to refer you to this, the sticky to end all stickies, but ALL of the information you need to know about the tire wear that's endemic to these cars is located here:

Does that part of your tire even touch the road? Is that the inside of your tire? Wheel/tire specs?

 

My friend just bought a G35 about 2 months ago and it had brand new tires. Just a couple weeks ago we pull the wheels to plastidip the rims & the tires up front look exactly like yours. Driver tire was worse than the passenger tire. In his case the lower control arm bushing was completely shot. The arm had visably moved all the way forward on the mounting bracket.

 

Chianti and Fava Beans, there is a call for Chianti and Fava Beans on the courtesy phone.

 

Compression arm bushing and destroyed control arm bushings will do this

 

This is what I thought

I just put on RS-3's in 285/35r18 265/35r18 today. I am going to put the Z away early this year for the winter and work on suspension. Next year, I will be orienting the Z towards autox and maybe take a stab at my first HPDE as well. I will still put about 3-4k miles on the street per year.

I am on a budget but will definitely get SPL Compression Bushing as well as Lower arm inner and shock bushings.

On the wish list are:

-SPL v3 arms
-Do you think these are necessary now for autox and HPDE to dial in more camber and get good tire wear? I will be looking at -2.0 but think I should be closer to -2.5. Keep in mind some street driving as well.

Down the road are better coilovers (currently on BC BR, oh well), potentially sways and adjustable endlinks.

 

Thanks, but from what I understand, the tire feathering issue results in a more lateral, choppy wear. This case seems to be different.

 

My last year of having my car as a DD, I ran -2.7 and put 20k on it. The tires still lasted just fine, I could have gotten maybe 5k more on then ( I ran V12's on the street, and different track tires)
