Anyone test alignments?
 

The car appears to have a large, maybe 2 degree negative camber on the rear, but zero on the front.

Anyone do any testing with front camber and caster, or the rear camber? I ran a lot of negative camber at the front on my last car, and it was a power rear steer monster, lots of fun.

With the Z, I'd guess the large negative rear camber makes it very hard to get sideways.

I haven't been able to drive my car to the limit yet, to see how she handles, with the cold and new engine.

No problem getting my Z sideways with the stock setup. Most of the time I prefer it not go sideways though.

Yes,i also noticed the rear have negative camber,what worries me is the rear tyres may wear the inside part first..

Related subject, dudes (doubt): My Z tends to drift slowly to the right while I'm driving at over 25-30 MPH. I checked the air pressure in both front tires, and they were a couple lbs/psi apart, so I inflated both to the right lbs/psi. I STILL got the "right bent" problem. Any suggestions, before I go blow away some moola at an alignment shop?! Thanks!

on these cars -2degrees in the back is normal.

Thank you for the alignment specs! As I guessed, about -2 on the rear...

The rear tires will definately wear more on the inside edge from normal driving, and will clearly show the -2 camber effect in an uneven wear pattern. If driven on track or very hard, this will partly offset the un-even wear pattern. And we cannot rotate these tires. The handling will get worse as the tire wears into the cambered pattern, and a noticeable edge shows.

What I am wondering is if anyone had increased front camber up to the max negative, -1.41 deg, and noticed any difference in feel?

I also have played with caster in my old car, and noticed a significant difference. More caster gave the car a much "calmer" feel when driving straight on, a bit steadier, and a bit more feel. Also makes turning the wheel harder. The Z appears to come standard with what I'd consider to be a lot of caster.

I also ran low pressure in the front of my old car, which was not good for wear, but increased feel at the limit. About 26psi cold, versus 32psi rear.

If that were the case then we would have an uneven tire wear "issue". Anyone experience this yet? I have 12K miles on my Z and the alignment seems spot on as I don't have any abnormal wear patterns.

Maybe the tires are designed to have a bit more rubber on the inside than the outside, knowing that camber will be negative on most cars that will equip them?


You can definately feel a difference in heat between the inside, middle and outside...

Not sure what mine was stock but after some suspension mods my rear was at -1.7 camber and at 8k miles my rear tires were bald on the inside. At 9k miles now and today I am having rear toe bolts installed so I can get -1.2 rear camber to get a more even contact patch and make my tires last longer.

That's not eough camber to trash your tires like that...You probably have a toe problem.

Moderate to aggressive driving will wear the tires evenly (more outside wear in turns balances out the inside wear on the straights.)

NO!

Awesome thread! Thanks Mod shack!. Is there are more aggressive setting besides the stock setting on stock suspension. On the S2000's there were Euro specs that were more aggressive than US specs. Does such a thing exist with the Z? Also I'm guessing minimum on the chart means stock settings correct?
