RCZ's 370Z Journal.

Here's what I'm running, generally happy with this

Front camber: -2.00
Rear camber: -2.50
Front caster: +6.00 (stock is 5.0)
Front toe: 0.00
Rear toe: +0.10

I'm not the world's expert on all this but here are my thoughts...

I have less front negative camber, but I get more front roll-induced camber because I set the caster +1 over stock to 6.0. I like the higher caster angle b/c it helps hold straight track with a neutral to slight toe-out setting. I may toe-out front a hair to get quicker turn-in response and scale back understeer, but it is pretty much fine now and appropriate considering stock bushings create some minor compliance and toe-out under acceleration. I have modest rear toe-in now and will probably have that dialed to neutral or slight toe out next time around... Some rear toe out would be appropriate to help balance out understeer tendancy and more if you like to hang it out... as you mention tire life is tradeoff on toe settings.

The only thing I would worry about going toe out in the rear is bump steer. When under braking or going over bumps where weight is transfered off the rear, raising your suspension, your toe will go out even more and could cause some pretty hairy moments under braking.

The guys I went to are pro, and when I say pro, I mean they are no joke, and mainly setup track porsches etc

The guy I go to is also very good, he setup a couple of big time winning cars apparently. I'm not sure where your settings are, i looked at your journal and didnt find much in the way of a setup, just some camber settings.

I will take this into account too. I am going to ask him what he thinks I should do as well and go from there. I'll let you guys know what I end up with tomorrow. I'm not going to lower the front any more, just taking the rear up a notch so its even with the front. I know it could "look" more aggressive, but suspension travel is good on track...

No problem - Alignment/Corner Weight Results

I gave them the 2009 370z OEM factory settings that was posted on here as a baseline and told them to go more aggressive based on that...

Granted I havent tracked the car since then but it still feels solid. You might have to get it done twice just to get it the way you want.

That's a good point and considering this car is already light in the back prob better to run neutral rear toe or +0.1 like mine is now

RCZ · 06-24-2009, 10:38 PM

I think I'm going to keep the toe at 0 guys. Maybe 1/16th...will let you know what happens tomorrow night.

biggestbob · 06-25-2009, 05:18 AM

Got enough speed bumps? Eheh..... BTW, the stillen intake/exhaust system sounds awesome!

RCZ · 06-25-2009, 06:45 PM

Thanks!

Alright, so alignment went well. Everything is working brilliantly. I left the car up a little bit so I can clear my speedbumps.

We are doing a little bit of testing, went with -2 camber front and rear. and .05 toe in rear.

We will see how that fares.

beautiful journal, just went through the 17 pages so far

Thank you! It's been dormant for a little while, but it'll come back. Its too damn hot in Miami to do anything.

Tim · 07-19-2009, 07:55 PM

Car definitely felt a LOT better when the suspension was lower. I am going to set it back down and find a way to deal with the speedbumps...

LUVZTTZ · 07-24-2009, 05:33 PM

What's the status on your Stillen pulley? I'm curious to know what you think about it. Looks like the only mod left standing in your signature!

RCZ · 07-24-2009, 05:50 PM

Yup, never installed it. I was thinking about going to the underdriven ones. Next time the cars in the shop I might consider throwing it in...

From what I heard, not a huge difference, more difference with the underdriven ones. I may sell this one or trade with someone.

Well time to go bye bye!
