Z1 Motorsports 370z Adjustable Suspension Kit? Any Good?

Hybrids · 07-20-2021, 04:30 PM

Looking into swapping out the stock stuff for adjustable arms and all while doing coilovers at the same time. I was wondering if anyone here has used this "kit" and if they enjoy it? + it fits my budget.

I am mainly concerned about reliability of the kit since it is my daily and I don't want to have to worry about stuff going wrong down the road... also concerned about the fitment and quality of these arms? I have seen some z1 products lacking in either quality or fitment and this is one I don't want any problems with when I go to tear my car fully apart.

Another question is should I stick with the SPC adjustment bolt kit or go all out on the z1 toe arms too? It would be out of my budget if i went with the toe arms but would it benefit me any in the long run?

Not reliable at all. Bite the bullet and go with SPL. They will outlast the car and probably you and your progeny.

Useful for people needing to maintain rubber bushings, but the front upper control arms require removal at each pickup point for adjustment.

If rules allow for sphericals, then SPL is much better.

Get the SPL's. There is a reason why everyone here uses them. They work with no issues. You don't have to remove the arms to make adjustments like you have to do with other arms. The only reason not to get them is if you do autox and the rules say that you can't use them.

BettyZ · 07-20-2021, 08:58 PM

Just go whole hog and buy the SPL FUCAs, rear mid link, camber, and toe arms. Do it once and be done. You'll save $300 on alignments if you do it all at once, and you'll save infinity on alignments in the long term; because you'll never need one ever again.

Z1 is ****

SPL is bulletproof, better adjustment for you alignment tech, more range, better support

I only plan to keep this car on the street, I just want a better more responsive feel while driving. Would it be a waste of money to go with all SPL stuff if that is all I am doing with the car? If the z1 stuff is not reliable, what other brands would be a good option that would fill my needs? I am going to check out SPLs stuff and price everything out and see what I can do money-wise though since I really like their stuff and have seen it used a lot.

As has been stated above, go SPL and move on! My Z is a weekend fun car and may get out for a few miles, 1-3 times a month. That being said, I still bit the bullet and went SPL. ZERO regrets and will be buying more from them in the future given the quality, the ease of adjustment and the peace of mind that their parts provide.

Not at all a waste of money. Don't get me wrong, SPL is expensive as heck. But you're really buying peace of mind. SPL is about the only aftermarket stuff on my Z that I dont worry about when I'm driving

I had the z1 kit for years. Primarily for autocross. It's a pain to adjust but I never had any rattles. Good budget option for a person who is just looking to lower the car and won't be making changes all the time. SPL is great but completely overkill for that scenario.

Yeah but your first Z got murdered by hail which was attracted to the Z1 kit like filings to a magnet. It's #science

Lol. SPL would have stopped that for sure.

abm89 · 07-21-2021, 11:40 AM

I have the Z1 front arms. the only downside is that you have to take the wheel off to adjust the alignment, which ends up costing a little more. Other than that, my alignment specs have not deviated significantly in between appointments, so they are at least reliable. I would recommend SPL if you're going to change alignment settings often though, as the cost comparison will eventually favor the SPLs down the line.

I have SPL rear camber arms with the toe bolts. They work as expected.

I’ve been looking into coilovers with true style rears. Is there anything to replace the rear mid link with that doesn’t have the huge bucket for the spring?
