Wheel Spacers

[Dbrier]

Just an Fyi - I'm currently running 275s on the Front and 315s on the Rear with my new wider aftermarket wheels and there are absolutely no issues whatsoever with the fitment.

Bumping an old thread. What offset are your wheels? I'm thinking about going 20x10 with 275 tires all around. I'm guessing about 40 offset would work. these cars have lots of clearance.

To add to this, from what I know from speaking with Force Ten the setup has been working out great for him and looks killer!

I am OG so I love HRE wheels!

There is a pic on this forum somewhere of a bolt and it is 40 mm. Bolts at 55 mm are getting up there in length and would be concerned.

I have been communicating with Bonoss about this out of curiosity for my OEM 19" that I use for winter. My summers are custom offset of +32 which has my front tires flush. Back are a bit inset still but wanted square set up to allow rotation front to back.

It has been a battle Bonoss because they are in China, every email back takes a day turn around, if not longer, and they don't always answer my questions.

They finally pointed me to the link below and offer choices of thickness of 11, 15 and up (11 mm would be perfect offset to minimize poke for my 19s) and optional bolts bolts, direct buy.

You can then choose length of bolt here. Anything 52 mm up 75 are custom lengths.

Thing is, at almost $400 US just to have my winters a bit more flush, it's gonna be a hard pass.

I have a 2025 GV70 3.5. Bonoss has no idea what length stud to use with their 20mm spacer. The bit they sent bottoms out on the wheel hub after it passes through the spacer. Any help with proper length would be super.

Search this post , I did all the math with Bonoss rep and fits perfectly.

My guess is they shipped the wrong ones and want to bandaid it with sealing the bolts?

I did 20 and 40 and fit perfectly.

Soon as I land and all items load I can help with the math if still needed.

That looks great!

I have have this exact brand, size in box ready to ship if anyone wants a discount on them?
Even comes with all new black lug bolts so you don’t have those ugly rusty stock ones.

Message me if you want them before I post on marketplace.
The set I have is 15mm/20mm and is the perfect amount for stock wheels.

I even had mine lowered and zero issues not even a tire rub fully turned.
