Hey everyone, I need some help deciding if I need to purchase a SPC camber kit or anything else for my car. I just purchased 4 - Hankook Ventus V12 evo K110 XL for all around the car and want to make sure they get the proper lifetime.

This is what i was looking at to purchase: http://thmotorsports.com/combo_packa.../i-221817.aspx

2006 350z Touring

Riding 245/40/18 Front and 275/40/18 in rear
140K on stock suspension, Motegi Touge Rims

I've noticed on each previous set of tires even after alignment, the front inner tires would wear. I'm not sure if this is from lack of tire pressure or is a suspension problem, i've now set them all to 35 psi

 

350Z's come with slight negative camber from factory, and the 140k on stock suspension may have caused some sag in the springs which would account for additional negative camber.

Do you have a copy of the last alignment report you received?

I don't see a need for a camber kit if you have stock suspension, I'd look into replacing your struts/springs though (and then you'll want at least a rear camber/toe kit)

 

If you haven't lowered the car more than ~1", no camber kit is required. Just get yourself a proper alignment at a competent shop, and you'll be good. I just put the same barnd/size tires on my '08 (Rays LMGT4 wheels), and it's a fantastic setup. You'll like them. No matter what you do, though, the rears will still only have maybe 1/2 the life of the fronts - that's just the Z. Sounds like you have an alignment issue with the front, maybe from just the settings, or possibly worn bushings/balljoints.

 

I'll see if they have a record of my visits, this problem has been happening since the beginning of owning the car with original tires, as well as around 30k miles when i changed the size to what i'm currently running.


Any specific struts/springs recommended?

 

Just to clarify, how many miles have you been getting out of a set of tires, front and rear? If you got 30K out of a set of fronts, I'd say that's a pretty long life, and 20K would be really exceptional for a set of rears.

As for springs/shocks, ask 10 guys, you'll get 10 different answers. Check out the Suspension forum. I've got the Nismo S-Tune on my '08, and I wouldn't change a thing. Check out the classifieds, too, and some of the vendors have package deals on springs shock kits, like the Tein's, Tokico's, etc.

 

Around 10k the front inners of each front tire would be bald, and the rest of the tire would have plenty of thread left.

Rear tires i've never noticed a problem. I probably get 20-25k on rear tires.

If i recall correctly, the alignment shop I've been using stated he didnt have 'enough' adjustment and he 'maxed' out my setting.

 

Not sure what to tell you. Maybe the shop has the wrong specs? I think the '06> cars have the same alignment specs, and mine is an '08. I can get 25K on fronts, but the inside edges are bald at that point, but 10K sounds like there's a major issue with yours. I get almost 20K on rears, and again almost bald on the inside. That was with Falken ZE912's, which are harder than the Hankook V12's, and I've only got ~3K on my V12's now. Here's my last alignment sheet, and with me sitting in the car, the front camber comes into better spec, while with me out of the car, the RF is slightly off:
