18 x 10.5 square fitment

What lowering springs and are you using camber plates? I have nismo version, not sure if it needs those.

lowering springs? No sir

Topline Aragosta Type-S coilovers
SPL Parts all adjustable arms

The Z has double wishbone front suspension, which does not use camber plates. Those are for MacPherson Strut design cars like the S chassis, EVO, WRX, GRC

There is no front camber/caster adjustment on the Z, you must get Front Upper Control Arms, with SPL parts or nismo rebrand recommended

If you were aiming this at me, I'm running MCS coilovers. Ultimately, you'll see 99% the same clearances no matter what you use to lower in terms of coilovers. You may see some inner rub running stock front suspension as the springs are wider if you're going to go really aggressive, but I can confirm the 285's will fit just fine on the front with a +22 offset without any rub at all on oem suspension.

Optionzero is correct that camber plates don't work for our cars. Adjustable upper control arms need to be used. I'm running the Z1 forged arms, which I'll be selling soon here so I can experiment with the SPL as a comparison, but truth be told I expect them to be the same performance in the end. For clearance purposes they will all be the same.

Years back Z1 had a defective batch of control arms, and from what I recall, it wasnt fun for anyone that had to deal with it. Their original control arm design was not adjustable on car either, so they are really late to catch up

As a practical matter, Z1 isn’t a manufacturing company. They are a label that sells basically everything. The level of involvement in design varies, but they are almost certainly sourcing from elsewhere

this is neither good nor bad, simply a reality of our world today. The takeaway is to do a little digging before jumping in on large purchases

One simple test is to look around the paddock, or watch what is used on the track. I see SPL stuff getting beaten on across all platforms and tracks and everyone loves them. Nismo is using them under their brand (with different colors). My alignment techs literally said thank you bc everything is adjustable on car with locking mechanisms. Thats why im pretty confident in SPL stuff

also used them on my S14

Thanks both for the responses. My Nismo suspension feels alight, it just seemed like I was lacking lots of grip. Was hoping not to have to buy entire coilovers and wanted to just try new wheels/tires so I was looking at the suspension upgrade just to make sure there's clearance but sounds like I might not need any (getting -2.5 camber stock).

Very true, you gotta look at what's being used competitively, that's the quality stuff. I plan to get the SPL arms maybe next year. Will get baseline timings first with slightly lowered suspension and corner balance.

Z1 quality has been spotty, inconsistent with their labeled products, outsourcing has lessen the QC on parts.

It's amazing how much difference it makes with no camber. Mine are just tucked a bit at the top with -3 camber on +22 offset with 295 wide tires. I snapped some quick pics in the garage. Hopefully these are good enough angles to be useful to you.

You think this setup would fit with stock suspension, but with FUCA's for the negative camber

Yes, I ran this exact set up both before and after coilovers.

I'm looking to get some track wheels and tyres too. Is 18 inch a better option than 19? There is certainly more tyre choice in 18.

Are you on 40 profile too @Maximum_Jars?

 

[Maximum_Jars]

I ran with 18" for the cost savings on tires and also more tire options. The disadvantage is if you want to upgrade to a big brake kit later as not all bbk's will clear 18" wheels.

I've run both 35 profile and 30 profile. I don't generally like 30 profile as it's pretty harsh and you get more grip out of the 35 as it has a bit more compliance. I've never run a 40 profile as of yet.

Enkei is probably the most popular "budget" wheel used on track
They also bought Konig and vastly improved their selection, i've heard good things

Anything in 18x10.5 or 18x11 in the +15 to 25 range should be fine, provided you have front camber adjustment

 

[wisner99]

I ordered Bronze Apex VS-5's from their 4th of July sale. 18x10.5 +22 all around, excited to get them on the car. Probably going to do 275/40 all around for an easy fit. I'm lowered on Ark GT-S springs, and currently at -2.0 camber in the front. Might throw a 10mm spacer on the back too

For those new on this thread, here’s my fitment on 19” Nismos which is similar to 18” when dealing with widths and offsets. 19x10.5 +23 V2s square on 255/275 RE71-RS with maxed OEM alignment settings (front camber non-adj) no spacers. Plan to put on 285s square, still plenty room.
