Gotcha. Thanks a lot, man! Taking the Z to the shop this weekend.

 

I'm going to be installing tein s tech springs with some sort of aftermarket shock (likely koni yellows) and picking up rs3s/re11 on stock v2 track wheels, no other suspension mods. This is a weekend car which will see 3-4 track days this summer.

I know that with these springs I'll be able to get an alignment done within factory specs. However, what would be the recommended settings for my use on the track? Should I go as negative camber as I can on the oem arms? (Eg within the oem range, should I go to the most negative end of the range?)

 

Up front camber is your friend, you want as much as you can get -2 to -2.5 is pretty streetable. The rear, upper side of OEM works great -2. Toe, outer edge of toe up front, close to 0, and OEM rear, delight toe in. IMO , this would be a great starting point.

 

So for fronts, I'll go to the max negative within OEM specs (which is -1 minimum), or closer to -2 if I can, and close to 0 toe (oem is 0mm to 2mm, so I'll go between 0 and 1mm)

Rears, I'll go with upper side of OEM, so -2, which I believe is minimum according to OEM specs. For rear toe, what does it mean to have delight toe for the rear? for OEM, it ranges from 1.1mm to 2.7mm, with 1.9mm being nominal

Thanks for your help!

 

OEM front is about 0.5 to 1.1 and rear is 1.1 to 2.1, unless you have adjustable front arms , you can't change the front.

At minimum, I would match the front camber to the rear. Less front camber, less traction, more understeer. The front OEM specs suck.

 

On Dunlop Star Specs, after checking tire temps across the tires and watching tire wear since I drive the same tires on the street as I do at the track I have settled on the following:

Front camber: -2.2
Caster: stock (no adjustment)
Toe: -0.01°/side total -0.02° toe out

Rear camber: -1.8°
Toe: 0.15-18°/side (total toe 0.30-36°)

 

Is that for camber? I got the factory alignment specs from the posting by DavesZ#3 here:
https://my350z.com/forum/wheels-and-...ent-specs.html

According to that, front OEM range is -1.33 degrees to 0.17 degrees camber
Rears are -2.08 degrees to -1.08 degrees.

And since the fronts are non-adjustable (oem control arms), I can't do much right now, so i guess I'll just have the rear camber to -2.

for the toe rear, you mentioned "delight toe in", can you clarify? sorry I'm not familiar with these terms

 

For you guys running more than -2.0 negative camber in the front, what kind of A-arms do you folks have? Tried to have my car aligned yesterday and they they couldn't do more than -1.27 in the front. Currently running Kinetix 2.0 arms

 

I modified my Kinetix arms to be able to get more negative camber since I am at stock ride height. I was in the same boat as you but now I am currently running -2.2°, could probably get one maybe 2 more turns out of them to get near -2.5° (0.18°/turn).

To modify them I had a friend machine the threaded tube as far back to the U-shaped portion of the control arm as far as he could so it would give me more room to be able to screw the upper ball joint in to get more negative camber.

If you check out Kinetix webpage they have only designed these arms to give you an additional -0.5° or 1.5° camber. They are designed more for people that have lowered their cars and are trying to add positive camber to get the alignment back to OEM specs for tire wear.

which camber arm would you recommend for people running stock height? Trying to get to -2.5 on stock suspension

 

If I ever buy a different set of front camber arms it will be these: https://www.splparts.com/SPLFUAZ33.html

 

I just took a set of these off of my Z due to classing rules. (SCCA STU = no metal bushings)

I am now running modified Kinetix A-arms. I intend to sell my SPL's once I do a couple of events on the Kinetix. (I want to make sure the "modified" A-arms hold up under track use first)

 

I got -2.4º out of my modified Kinetix arms on stock suspension

 

Re-reading this thread...
Total noob question here.

When all of you say "1/8 toe out" in front..
Are you guys referring to total front toe? or each individual wheel?

 

Hi everyone,
I was wondering if anyone had their alignment specs for an autocross setup. I have been staying on the drag strip for two years and last year i started road courses and autocross. I really need some help in seeing what everyone is running as far as suspension setups. i have fully adjustable coilovers, sway bars, and i have two frame braces. i have all the pieces just need some figures, because as you all know drag setups are way different than autox setups

 

For my STU build:

Alignment:
F -2.75 camber, 1/16" toe out
R -2.5 Camber, 1/8" toe in.

This is a compromise (drive to the track) alignment.

 

what kind of tire wear are you seeing

 

I just went to these specs. After one two-day autocross event, it looks like the edges, (inside and outside) are wearing at a similar rate...but faster than the middle of the tire. I expect the insides to wear a *little* faster than the outsides over the life of the tire.

Since the Hankooks I'm now running require a little more air than other tires in their class, I'm hoping normal driving will wear the inside some and give the edges a little break.

 

ventus rs-3 v2?
