Bring on the flame, I'm absolutely ready and deserving for this stupidity.

I got into an accident with my last G, and decided to cheap out on the new one. 2010 G37X COUPE.

I bought these springs with the SPC BACK camber kit, ignoring what it clearly says in the title thanks to my stubborness, cheapness and the recommendation from a few forums and professionals that I could make it work no problem;


Installed them, let them sit a week, got it aligned, mechanic told me that he could not get it closer than 4.0 and that I would need a front camber kit. Ignored him too.

4 months down the line I see the uneven use on my tires and even some metal strips starting to show only on the back tires.

MY QUESTION IS, will a front camber kit really fix this? Even if it's the rear tires that are being used up and the front are perfect? or do I need to get different springs?

 

Don't be too hard on yourself, stuff happens and you get it addressed, which you're doing.*****I'm fairly certain you didn't install the SPC toe bolts in back, or if they're installed the slots haven't been elongated which is critical in getting your rear alignment proper. Unless these springs totally slammed your ride with something like a 3" drop your alignment in back will get back to spec w/ the rear SPC arms & toe bolts. Just curious how much drop those springs gave you, what is your measurement from the ground to the highest point in the fender arc? I'm at zero gap which is about 26.25" to the arc, I have F&R full camber kits and about 65k miles of perfect tire wear. *****Even with a drop of 2" the alignment shop should be able to get better than a -4, so I doubt they tried very hard **Oh, and FWIW there won't be a lot of difference in coupe vs. sedan springs, Tanabe uses the same exact part # for every G (except the convertible), the RWD, AWD, Coupe & Sedan all use the same spring and the drop difference is a 1/2" max.

 

Okay well that's very reassuring thank you.
I had eibachs on my last G but this seems slightly lower, advertised is a 1.25" drop, just measured it and its 25.98" to the arc so not a huge difference with yours but I understand these small differences can have big impacts.

I just rummaged through the old SPC boxes and found these which I assume are the toe bolts that should have been installed, unless there are separate ones I'm supposed to purchase (these are numbered 72056) ;


So now I guess I get these toe bolts installed and get the car realigned, at a different shop than my Infiniti dealer, correct?

 

Yep, that's your problem, at least in the back. At 26" to the arcs you'll probably need a front SPC camber arm set, but get those toe bolts installed and see how your alignment checks out. Might call around and see if there's a shop better versed in lowered cars, if the best they could do is -4 w/ the OEM setup maxed-out seems like they could get it better than that, but ???? Here's a link to the whole toe bolt install, it's really not a bad DIY but if you're not into turning wrenches then off to the shop you go https://www.myg37.com/forums/brakes-...-template.html

 

You are an absolute legend blnewt. You've helped me more times than you know. Seriously, thank you.

 

Not a problem, hope you find a good alignment shop.
