Hi Ps_Z

Want to share with you a suggestion from one of our forum member dpathfinder which helped alot with my alignment and made my Z really run very good. Read on and follow his suggestion.

As you mentioned the front upper arm for the Z does not allow much camber adjustment.
With this type of set up do you think I need to have a camber kit bolt on in front and rear?
I do not track the car mainly on street driving with occasional wild driving.

Thanks for the input.

Dpathfinders response:

It all depends on what you want to do. If you need to bring the camber back to spec, the OEM front suspension will not allow you to adjust camber at all. The rear camber can be adusted to a certain degree in the back. With a 1.25" drop up front and a 1" drop in the rear, which is typical of most lowering springs (even Tein S, despite advertising a 3/4 " drop, my friend's drop seemed more like 1 to 1.25"), your camber will likely sit at around -1.6 to -1.9 up front and -2.4 to -2.8 in the rear. I was lowered on coilovers and I decided to get SPC camber kits front and rear to allow for freedom of adjusting my suspension as I wanted. For an aggressive street/occasional track setup, I ran the following specs: F = -2.2 camber, max castor, 0 toe, R = -2.0 camber, 0.15 deg toe in. The increased front camber actually improves turn-in response.

So, I would recommend that you allow the springs to settle first and then do a wheel alignment. If your front camber is fairly even left compared to right and if your camber is in the neighborhood of -1.6 to -2.0 then just leave it. I suspect your rear camber can be adjusted back to a maximum of -2.2 to -2.4 with the stock suspension pieces. That may cause a bit of uneven wear. Ideally, it should be somewhere between -1.5 to -1.9. So if that bugs you, you can get a rear camber kit.

Hope that helps out.

Thanks a lot for the info bro!

Peter... when do you are going to get the alignment complete bro? we can go together hahaha!!

Wouldn't lowering the car change the caster? If the caster becomes further away from 0 compared to the stock spec steering response will decrease. What is the stock spec and what did your alignment sheet say?

thanks again zoren! i do in fact have the spc rear camber kit, so adjustments can easily be made. up front is completely oem. ill be going back to the shop in about two weeks to let the springs settle, and ask for the specs suggested. lets hope they can also provide the alignment sheet this time
