Here is my setup right now before lowering: 2003 350Z Touring

19x8 front wheels +40 offset
19x9.5 rear wheels +20 offset


I am going to be lowering the car with Tein S Tech springs. The front wheels are getting Ichiba 25mm spacers and the rear wheels are getting 15mm Ichiba spacers. Every person I have asked seems to have a different opinion on my question, and I want to make sure I get everything I need before dropping it off at the shop. With this setup, will I need to purchase any sort of camber/toe adjustment for the front or rear of the car ?

thanks in advance for you guys help

 

30 views and nobody can respond ? lol

 

I just had my 2005 Z lowered with Tein S Techs. After they were installed, I went and had a performance shop perform the alignment. They suggested a camber kit.

Lowering the Z will increase the negative camber, bringing it out of oem spec. The rears are affected the most. If left alone, it will cause greater wear on the insides of your tires. One thing that many people do is swap their rear tires around every 5k miles to promote even tire wear. Naturally, only non-directional tires will allow this.

My suggestion is to go ahead and purchase the camber kits and have them installed with the springs. That way you will only be charged for one alignment job.

 

An eibach(SPC) rear camber kit purchased from ajusa.com is a cheap investment to get your rear camber/toe back in spec, ~$150 shipped

 

greatly disappointed with the lack of responses lol

 

You don't NEED to but if you're really worried about tire wear then yes, go ahead and get some. Tein S-Techs don't lower the car too much, so I wouldn't worry about it.

It's really owner preference.

 

Before you do any lowering make sure your spacers don't push your wheels out too far.

+40 in the front and +20 in the rear? Are you sure these wheels were meant for a Z. That's a drastic difference ins offsets from front to back.

If you're dropping an inch or more you'll need a Camber/Toe kit installed in the rear. Front camber/toes kits are about twice as much in price, so I would only get them if you really need it.

Also if you plan on running stock rear camber (-1.6 degrees) you'll probably need your fenders rolled.

 

yeah, the wheels weren't meant for a Z, but they've been on for over a year now with no issues. I've been told that the spacers are basically comensating for the offset, which will be fine (correct me if I've been told wrong). And I'm only lowering the car .7 inches with the Tein S Techs so it isn't really going to be an issue with clearance.

 

You probably don't need a rear camber/toe kit then. Make sure you get an 4 wheel alignment from a reputable shop after you install the spacers and springs.

 

Is an alignment necessary when just installing only spacers?

 

I didn't get an alignment after I installed my rear spacers, but it wouldn't hurt. My tire wear is still even after 5000+ miles.

 

Thats becuase your a pimp baller with the Convert

 

my main concern the the front wheels since I am using such large spacers. Should I be ok as long as I get an alignment ?

Some tires like Nitto Geo Gens have lettering on the side walls that read "Inside" and "Outside". Would it be safe to reverse these when tire wear becomes an issue along the edges?

 

Some people have swapped front wheels to even out feathering. Rather than dealing with that, just get the camber/toe set properly (not sure what kind of wear you're referring to) so that you don't have to deal with it.

it's more of a pain in the ***, but it's well worth it in the long run.

 

The fronts shouldn't be that bad. I was looking at your rears, though... 20 offset with a 15mm spacer? Maybe I'm reading it wrong, but then you're looking at a 5mm rear offset? That seems a bit excessive considering the wheels you are running.

I'm not an offset guru so I may be off-base here.

 

^^^ possibly but what would be the downfall of that aggressive an offset ?

 

Wheels that stick out farther than the fender and terrible fender rub every time you hit a bump.

Plus it would look really stupid.

In my opinion, don't worry about rear spacers. +20 is fine.

 

Look people are going to have their personal opinions about offsets and whether or not an aggressive offset looks good blah blah blah. Do what you want. You may get some negative feedback but oh well. I am running a -2 offset on my rears and I love it. So do what you want. Don't listen to what people say. But I don't think you will need a camber/toe kit
