I know that there are certain allowed ranges in the 350z recommended alignment specs, but I'm wondering if there is anything to be gained in tweaking alignment (eg changing camber / toe) from stock specs. I'll be taking my car to the track next month.

For those of you who track their Z's, what would your optimal alignment specs be and why? thanks

 

1/4 track?
AutX track?
Road track?

 

how about road track?

 

I am running T2 suspension, 700 lb springs
EVO control arm, Evo sways on med F/R
SA Koni full stiff

Front camber 3.0 deg
Rear camber 2.2 deg

275x40 V710 tires on 17x9 wheels

Well balanced, and can bring out the rear with power

 

Please forgive my ignorance. I always thought you couldn't adjust camber on the Z, but I see here that apparently you can (perhaps C RAY Z uses aftermarket hardware) But still, I said as much to a tech at Nissan, and he said something like, "Oh there are ways to adjust camber".

In fact, I think they used one of their "ways" to curb my tire feathering. He said Nissan suggests +1.0 degree positive camber to help with feathering. In turn, the outside edges of my tires are worn down, and the inside edges are perfect. My real question is relevant to this thread... How would you adjust camber without using aftermarket hardware?

 

You can't, not in the front.

The EVO control Arms is what C ray Z used to adjust his camber.

 

A bit off-topic, but what are the camber settings for the Z's stock? My Z definitely has a good bit of camber from the factory.

 

Front camber (on '04 and '05 at least, not sure of the others) is between -1.33 and +0.17, nominal being -0.58

 

sweet you have the tire and wheels setup I'm looking into this season. Does the car have crazy turn-in with 3.0 camber? Being that I was running the typical stagger of 245/275 and had my sway bars f/med r/stiff with an alignment of 1.90 front 1/4in toe out and 2.1 rear 1/4 toe in, I was hoping 275s all around with adj front camber arms would cure the understeer (autocross).

 

with 275 all around and -3 degrees camber there is absolutly no understeer

 

Wow I wish I could have a 275/40 tire.

 

They sell them at TireRack...

 

not in 18

 

Oh... Right.

How about fitting 285/30R18 instead?

I'm going 17in for the track. Way more selection!
