open lugnuts which size?

[void_kp]

Hi folks,
I've recently got a set of apexi wheels (love them btw) but I need to change lugnuts to get some open ended ones.
What is the thread size of the z/28?

which one of these? https://apexwheels.com/accessories/w...Pitch=m12x15mm

[void_kp]

I found M14x1.5mm .
What I believe the remaining specs are: 60 degree conical.

Can you please comment on which Apex wheel you purchased, and what specs (F and R)?

Did you stay square and stock tire size?

Not to thread jack, I went with Apex SM-10 in Anthracite 19x11 +11 all the way around. It gets that back tire out a bit .

^ beautiful set up! Well done.
What size tires are you running front and back please?
And the wheels are 19X11 ET11?

I contacted Apex a couple years ago and they recommended the 19x12 in the rear. Any reason you went with a square setup? Any spacers? I asked them if the 12 would fit without spacers and they wouldn't answer my question. Just told me the wheels would be wider or something general. I found it odd.

Your wheels look fantastic though!

no problem with questions about rim sizes. I've also ordered the MSI wheel nuts (open ended), will see how that goes.

Here's what I bought:
Apex SM-10 19x11" ET11 Wheels - 5x120mm / 67.1mm - Satin Black SKU: SM101911ET11-5120-671-TC-SMBK
Apex SM-10 19x12" ET41 Wheels - 5x120mm / 67.1mm - Satin Black SKU: SM101912ET41-5120-671-SMBK
There was a memorial day discount and wheels were 20% ( I think) cheaper.

I'm not into forged wheels for track usage as forged are lighter but less elastic, they can easily break with strong impacts (i.e. curbs). These are good wheels, light enough, good style, good fitment, good price for the overall quality. Support was amazing, 10/10 recommend to anyone.

These are going to be my track wheels. I'd like to downgrade to 18" wheels (more tire choice and cheaper tires) but in order to do that you have to "modify" the wheels and it's something I'm not fond of.
As a result I anted to keep OEM tire size. What I went for is:

I strongly recommend to reach out to apex fitment support, here's their answer based on the data I provided:

Hi , thanks for reaching out. The camber settings are just there as recommendations for track use. To be honest, a Z/28 can run 19x11" ET11 front and 19x11" ET35 rear without any mods. Many owners prefer the rear fender fitment of 19x12" ET41 better as it's more flush to the outside than the 19x11" ET35 is.

In the end I picked the 19x11 ET11 [edited] front and 19x12 with ET 41.
I've installed 305/30/19 tires (Goodyear Supercar 3R) and the fitment is good for me. Even on hard cornering on track you don't scrape the inside of the wheel arch.

It's hard to see on pictures but front fits like OEM and back fits better than OEM (more flush with body, as the support said).
Apologies for dirty car, I didn't have the time to clean it after last track day due to a pet medical emergency.
But as a bonus I'll show the grandma in the same garage.

Thank you, no spacers. I felt the wheel needed to be pushed out a bit to compliment the rear flare as the front wheel does and the offset of the 12" didn't get me where I wanted it.

Curious why you went with the +35 in the front? Also, why is Apex saying "can fit" a 19x11 +11 in the front? That's factory size and offset...

apologies, I realized I made a typo. I went for ET11 in the front, not 35. Just OEM ET in the front

Oh interesting. Alright that sounds good! Thanks for answering!

Cars look great! I think I would definitely go with the 12 in the rear too. Especially since you say they don't need spacers. That is great to hear! Thank you!

What is the thread size of the z/28?

I have some Of the black Forged Gorilla lug nuts that are open ended. I believe they are from my SS which is the same thread pattern. I can take some pictures tomorrow and if you want them you can have them for the cost of a small flat rate box from USPS. Which is like $10 I believe. I didnt like them because my wheel studs always looked rusty, so I swapped to a closed end lug nut.
