I am running Tein S-tech and have also had the dealer install the SPC camber kit on the rear as well as SPC toe bolt kits. to this day I've been to Nissan and Infiniti several times and no one can get the alignment right. In fact, the last alignment Infiniti did only got me about 2,500 miles out of my last set of rear tires.. what in the world am I doing wrong? They are not claiming responsibility and there are no custom shops in my area that specialize in lower vehicles. Also, ever since I changed to these springs the back end always felt like it was very loose and jittery, even over the smallest bumps. Handling and traction in the rain is especially bad..almost scary. I'm wondering if going back to Eibach springs would solve the issue because I did have those prior for about a year and had no tire wear issues. I'm on my second set of rear tires in 5 months.... any insight would be appreciated as this has been so frustrating!

 

It's not camber that kills your tires it's toe. If you can have your toe aligned to 0 then you should be set. My car is lowered on Tein Street flex coilover and I have no problem with toe alignment with stock camber kit.

 

If you do get it aligned to 0 and still eating through your tires I would check if the springs were installed correctly. I'm no professional but I would guess that it the springs aren't placed right in the seat they are going to move around and mess up the suspension dynamics.

 

That's what I was worried about. I tried to take it back to Infiniti to have them re-check the installation and they don't even want to mess with it now. I think I found a good alignment guy after hours of searching and will try him out after my new rear tires arrive. I'm almost tempted to just change the springs back to eibach anyway just so I can actually get some life out of my rear tires. Front are still great and had them since 4 or 5 months ago but the rear is just getting eaten up like crazy...

 

Infiniti is claiming the had the toe set at zero, however now I remember they didn't provide me with a printout at the time it was done.

 

I am running close to 4 degrees of camber in the back on some TOYO T1S tires and they have a 240 treadwear. After driving about 5000 miles they are showing signs of camber wear. I know I can get another 5k without worrying about changing them. Let me know if its the toe or the springs. Also you dont have to take it to the dealer they are designed to rip you off. There are alot of wheel and tire places that do alignment.

 

Do you think it makes any difference that my tires are pretty low profile on Vossen 20's?

 

I'm running 20x9.5 +15 with 245/35/20 and 20x10.5 +35 with 275/30/20. I'm not sure, but with my setup almost all of the tire makes contact with the ground. I don't think sidewall matters. Maybe widths do? Post a picture of your setup maybe I'll get a better understanding of what you mean.

 

This is 20x9.5 +25 with 245/35/20 and 20x10.5 +35 275/30/20

I added a 10mm spacer up front a couple months after these pics were taken.

This is when I took the wheels of for the winter.
Front (you can see camber wear, and this is after about 5k miles)

Rear (also after 5k miles)

 

OP, your problem is w/ the camber/toe kit and not the springs (at least the alignment problem). I was previously dropped the same as H&R springs on my B&G S2 springs (which are just slightly lower than S Techs). My rear toe was well in spec and my camber was just -.6 degrees. I had perfect treadwear and now have 25k miles on my 295s w/ my current coilovers and can go another 15k miles. They're A/S tires so they should wear a long time, but the totally even treadwear is what I'm emphasizing.
I doubt the toe slot was elongated properly &/or the technicians aren't up on aligning lowered cars w/ aftermarket camber kits.
There's no reason a competent shop can't get your G into perfect factory alignment specs w/ the F&R camber and rear toe kit.
G/L and hope you can find the right guy for the job

 

Op you should go demand a printout to see if they indeed actually worked on the alignment. Also take some pictures of the installation. Who knows maybe they installed the parts backward. You need to understand dealerships are specialized in oem parts ONLY. Don't expect them to install aftermarket parts correctly.

 

Can someone post their alignment specs so I can take it somewhere and they have something to go by? My front is wearing fine but the back is the problem

 

Son. As I've mentioned before you should take a picture of the installation and make sure the toe bolts are on correctly. Showing you a spec sheet is useless if the techs can't even get the alignment close to spec with the alignment kit that you have.

 

Gotcha, I will get some photos. How likely would it be that a camber kit installation or toe bolt install would go wrong?

 

The camber kit is straighforward, the toe bolt is something the avg. alignment tech might not be familiar with. Cutting into an OEM bracket isn't something that's typical for sure.

There's been members here & on G35driver that have had the alignment guy just install the new toe bolt in the unmodified slot and twist the washer to the point where it won't slide any more and be done with it. This will result in toe being quite out of spec.

I'm thinking this is what's going on w/ your situation, or the tech isn't up on aftermarket camber adjusters
