Wheel alignment

Faded2thamoon · 09-09-2017, 10:50 PM

Just got an alignment, car feels fine doesn't pull or anything. It's my daily so I'm not sure if this set up is too aggressive or whether I should adjust anything? Looking for feedback, car is lowered on ARK gts springs with SPL rear camber arms.

Your rear toe is way off; though it will drive straight-you will scrub your tires off quicker,as they are turned inward way too much.
You can even see the (X) showing it out of specs.
Staying on the maximum side of toe; will make car drive straighter & feel "Less-Nervous" at higher speeds.
Factory specs in degrees are listed on your chart in small #'s....& maximum is 0.12*F per side & 0.22*R per side.
You should be able to adjust your toe closer to spec than that w/eccentric's located on spring bucket's.
Your camber is more track oriented & for curvy roads....expect accelerated tire wear-especially if you do a burn-out.
Nominal Specs should be your target-if your wheel/tire set-up will allow it.

SPL makes all the part to put front & rear in specs...you have to find a shop familiar w/these cars to perform the adjustment.

^He provided great info. I would suggest getting and installing some SPC rear toe bolts and taking it back for realigning. Your camber should be fine once you get that toe zeroed out.

Doesn't look like they changed anything.

Thanks for the feedback! Just ordered the rear toe bolts, waiting for them to come in.

Just be sure & have a competent alignment tech. working on your Z,
As a Toe adjustment on rear,will also effect the camber.
The rear suspension is set from the factory with twice the amount of negative camber (top of tire leaning inward) and twice the positive Toe (Front of rear tires turned inward).
Max rear toe is (0.21* or 0.213") some alignment rack's read degrees & other's in thousandth's (some have both).
Your Front toe is OK-though it's near the maximum of spec...
Your Rear toe is 4x more than max...You should be able to get the toe corrected;
but unsure your ending camber result's.
May end up needing Front upper control arms & rear mid-links,in order to get alignment's back to oem spec....as those springs go pretty low.

I'm really surprised they gave you a printout of the alignment & all those X's ...I turned pic for easier reading & as May's said,,,doesn't appear they touched the rear. I can see a slight front toe adjustment. Here's a picture of quality parts for lowering & really dialing in your specs....not cheap-but Good Stuff!
