Except I can tell you those look like cheap, generic spacers. Spend a bit more and get a proper set like H&R. Check out Z1 Motorsports.

On z1 i only saw a 20mm I need at least 25mm to clear my calipers, and i was hoping to get ones with studs built in not the ones where you have to get extended studs because when i go back to my stock wheels im not gonna be using spacers.

Thanks for your response, ill look at some other companies to see what they have. I was just wondering if the spec of the spacers i found on amazon was correct for my car to ensure proper fit.

As I already mentioned, no one is going to be able to answer that without you providing you current wheel specs ...

Thanks for the link, I don't know how I missed that. As for the fitment I mean the spacers fitting to the car. But now that you showed me these I think I'm all set.

Thank you for taking the time and helping my noobness.

Yup, those should fit just fine.

For the record, hub size on the 370Z is 73.1mm. The inner bore size is 66.1mm. Hubcentric rings ?

Any way to avoid open end lug nuts with extended studs?
Looking to add 15mm on the rear on 18x10.5 +15.. i currently have rays lug nuts.

As long as you size the studs properly, you should be good.... can you get studs that are 15mm longer than stock?

I have 15mm spacers and extended studs and don't use open ended lugs

I have 15mm stud replacement spacers from H&R all around, but am toying with the idea of Swift springs and would want to jump to 20mm for the rear. H&R said I couldn't just swap the spacer itself because there wouldn't be enough thread, so I am wondering if I get a pair of 20mm bolt on's will the extended studs from the 15mm set fit in the cavities in the back of the wheel? (Sport model for reference)

RanRich · 08-29-2017, 08:58 AM

Bueller?

TLDR; I have 15mm stud replacement spacers, can I use 20mm bolt-on's in the rear without issue?

5mm ain't that much you should be fine.

Leaning towards running the ARK GT-S Lowering Springs w/ the Nismo OEM struts along w/ a rear camber kit. A couple of questions.

-Will I need wheel spacers?
-Will I need toe bolts?
-Will my car scrape w/ this setup? (Car has to remain functional and driveable).

RanRich · 08-30-2017, 12:48 PM

Spacers - personal preference. If you don't want the sunken wheel look, yes. 15F/20R will do the trick.

Toe Bolts - yes. SPL arms and their "eccentric lock out kit" seems to be the way to go.

Scrape - yes. This drop is more aggressive than the Swifts, and will wear your shocks quicker as well. Just be wary of inclines for driveways/parking lots.

Thanks.
Will my Nismo OEM struts be able to handle the lowering of the car?

Yep. Most people run springs on stock shocks and report zero issues for tens of thousands of miles. The things to keep in mind are spring rates and reduced right height, as these will effect shock travel and stress. Hoping to get a set of swifts in the future and will not be worrying about damper replacement.

Are extended studs worth the $$$ for me ? Not doing any track time and it's a weekend car. Got a pair of H&R but didn't realize they were not bolt ons. Going bolt ons in the back and either installing the extended studs ones I have and paying for installation or selling them and picking up a pair of bolt ons for the front. Have read some say go for the safest bet = extended studs but have also read many state they are full bolt on with no problems at all.

Going 20 in the front and either 20 or 25 in the back, lowered on swifts, on stock sport setup. Anyone ?
