Z getting coilovers- Camber/Toe question

[hipertec]

Dropping the 2024 Z by 1.5 to 2 inches is a pretty big move since the suspension is basically the 370Z setup and gets pretty cranky once you go that low. If you don't add some supporting parts, you're definitely going to chew through the inner tread of your tires in no time because of the negative camber and toe issues that happen naturally when you lower this chassis.

For the rear, you absolutely need adjustable rear camber arms and rear toe arms. The factory bolts just don't have enough range to get things back to a safe spec after a 2 inch drop. I'd also highly recommend a lockout bolt kit to make sure your alignment doesn't slip over time.

The front is actually more of a pain because there is zero factory camber adjustment. You’ll need a set of front upper control arms to fix that inner tire wear. Brands like Z1 Motorsports or SPC are common choices, but make sure you get ones designed for a lowered car so they don't hit the top of the strut tower on bumps.

Also, let the coilovers settle for a few days before you take it in for the final alignment, or you'll just end up having to do it twice once the springs find their final height.

I ended up going with some parts from a local aussie brand gktech - camber arms, adjustable toe spring buckets, and two eccentric delete kits.

The toe buckets aren't as sexy (or expensive) as the nismo or SPL ones, but they play nice with the HKS springs while also allowing me to run any 2.5" ID spring down the track. Now I just need to take it back to the alignment shop.

thanks for all the feedback. After the installation on my Z:
FRONT Drop of 25mm (1") and REAR drop 32mm (1.25")
Right now my specs are:
FRONT: Toe at 0; Camber -1.5 Right, -1.8 Left
REAR: Toe at 0.5degree; Camber -3 Right, -2.9 Left

What is the best way, without changing every part of the suspension, to keep the inner tread from wearing out? I dont mind if its off by a bit, just dont want to invest a ton of $ and time changing out all the parts.

Or do you think a good alignment will be OK?

I don’t think you understand why I recommended new parts:

there is no front camber adjustment from the factory
sorry
dont get mad at me, be mad at Nissan

rears have eccentric bolts with a range of…half a degree?
again, blame Nissan

if you wanna be low, you need arms

Expensive, but if you want to do it right.

OK, here is what could be done, a very reputable local alignment shop's laser alignment. I'm on just Swift Spec-R springs, stock arms, shocks, etc. for now, about 1.1" to 1.2" drop per the spring specs. The recommended rear camber was reduced slightly on negative, toe was still w/in range, no problems with the stock eccentrics. Per their experience this will balance out the handling.

I wish I'd bought the full kit in hindsight. I'll end up buying every bit individually eventually

Yeah, I only bought the rear camber arms originally and quickly realized if I'm going to lower over an inch I need all the rear parts to keep the wheel straight in the rear.

Yep! I just put the adjustable buckets in with the camber arms. Now wanting to go lower and wondering if I need the FUCAs.

All part of the fun I guess!

The Z1 and SPL kit was so much more expensive. I was thinking of going Aliexpress until I found this.
