Not always, depends on who aligns your z. I've noticed with my tires the inside and outside wear evenly. I'm at about 12k.

Depending on the drop he might not be able to get the car back to spec.


I have the swifts and I can tell you that you will need camber arms to get measurements back to spec. Can't speak for eibachs though.



OP if you are interested, I have a set of Nismo springs for sale that will drop you .4'' You should be able to get the car back to spec with those and thus not eating tires. PM me if you're interested.

Ron, did you get camber arms for the front wheels? I think my front wheels still has a little bit of negative camber. It is currently -1.6 and -1.5 for the front left and right, and -2.6 and -2.5 for the rear left and right. It's probably slightly worse now after a couple of days.

Yep I got front and rear camber arms and adjusted them to the same length as stock when installing for the time being.

Rear camber is pretty noticeable now, fronts don't look that bad but I'm sure I'm out of spec. It's been a week since the install so I'm getting an alignment tomorrow. I'm sure your camber increased if you got the alignment done the same day of the install. It took my front 4 days of driving around to settle from 2in wheel gap to 0.75in

Hope that helps! :)

the reason i was asking was because i havnt lowered mine yet and since my tires in the front wear on the outside more, if i lower it shouldnt it make it wear more evenly without a camber kit (just in the front)?

how strong are the stock non-nismo 370z struts? how long can it withstand a 1-2 inch drop?

Well you are the exception not the rule, as most of us with Swift Spec R's do NOT need camber kits. I was able to get mine to -1.4 front and -1.9 rears.

If you stay under an inch you should be fine. Tein H tech springs have the most mild drop, more so than Swift or Eibach. (about .5" drop I believe) but are harder to find.

you need an alignment. alignments from the factory suck.

OP if youre on the lookout for springs let me know and I can get some for you, Swift are currently on back order, the Tein H tech are special order only and the eibach are good in stock, I'd say one of these 3 won't kill your tires, but definately do an alignment and if you're still unsatisfied buy a camber kit ( the Rear SPC kit is like 200-300 so its not horrible)

damn i had no idea that factory allignments were bad haha. i thought it was just normal for the car. thanks though

Toe eats tires, not camber. The toe is likely going to be what goes way out of spec when you lower the car. The SPC rear camber/toe kit is cheap. Just get that and have it installed when you do your springs. The fronts you'll most likely be OK.

correct, however camber will wear the inside of your tires moreso than the outside, leading to lower treadlife. im "slammed" with no wheel gap with my coils and my front camber is -1.7 and rear is -2.5, but the toe (front/back) was able to be brought back to factory specs without any camber/toe kits. and by the way...my toe was horribly out of spec after my install!

I finally decided to go with the Swift Spec-R lowering springs and SPL rear camber arms and SPC Toe Bolt installed. Some guy from Precision Z told me that the SPC front camber are trash cuz the caster and camber is all together in the same joint so its almost impossible to get alignment back to spec. He said with the mild drop i can get my front pretty close to spec. i hope he's right? cuz im not trying to buy a set of front tires ever other month since my Z is my daily driving car.

yea they can fix toe but it increases your camber. they fight themselves if you dont have a toe kit. that was my understanding during my cars alignmment. they can get camber back to factory but toe starts to go.

bottom line you need a rear camber AND toe kit if you have any signifigant amount of drop. (1"+)
