I see this has been asked before and forgive me if this is in the wrong category. I’m looking for a single rotor spacer for gen 4 wheels to make it fit my gen 5 10r. I bought a set of OZ piega wheels for my gen 4 but would also like to be able to use them on my gen 5. I believe I read that I need larger captive spacers along with the rotor spacer. Does anybody know of a retailer that still sells these? Everywhere I look they’re all sold out and don’t offer them anymore. Does anybody on the forum make them currently or could make them for me? I believe all I need is a 5mm spacer to push my rotor out to be in line with my caliper. I’ve had conflicting info saying I need larger captive spacers but also read that the OEM spacers from a gen 5 will work. Can anybody chime in and give me a little more info??

You dont need wheel spacers. AFIK the only difference is the diameter of the brake rotor. Only the RR has narrower wheels requiring a rotor spacer


Your Gen4 wheels should fit using your gen5 spacers. If necessary order a set of Gen5 spacers.

The only difference was 310mm vs 330mm rotors.

I figured the wheel spacers would be good to go but my main concern was the rotors. I contacted a guy that used to make them on the forums and confirmed I need a 5mm spacer to align the brake discs with the calipers.

I do not believe that is true. Please post here what you find. The misconception comes from what dimension people are referring to. In order to use Gen5 rotors on a Gen4 spacers are required to move the caliper out from 210mm to 330mm. I do not believe the rotors spacing (width) is different between Gen4 and Gen5.
Please prove me wrong.

IF you are correct, then the RR Marchesinis should fit on the Gen4 without issue, as the RR has a narrower wheel and requires different brake rotors. On the flip side, If you are correct, the RR rotors should mount to the Gen4 wheels and work on the Gen5 just fine.

There is a lot of conflicting info out there. I have yet had anyone actually measure the rotor face to rotor face distance on a Gn4. to compare.

OZ wheels should be here in a few weeks and I will report back with the findings to finally clear the air.

I just looked up the wheel spacers and the Gen4 are 32mm and the GenV are 40mm. Thats 8mm per side. Which are the same spacers used on the RR Marchesini wheel. So now curious to measure the rotor pad on the wheel.

I wish I had a Gen4 wheel handy

after some digging I found that I can use the OEM gen 5 WHEEL spacer. Supposedly I need a 5mm spacer for the brake rotor to make a gen 4 wheel work on a gen 5 bike.
Here’s the forum I read and I contacted the person selling the spacers and he said all I need is a 5mm spacer for the rotors.

In order to use 2011 to 2015 front wheels on the 2016 bike, you need to space the rotors out slightly, and also use 2016 wheel spacers. Once you've...

Hi, I saw ur post and I have the same issue. I have 2021 Zx10r and I’m trying to run oz peiga from gen4 to gen 5-6, I already bought a 5mm brake rotor spacer to push the rotor out. But what do I need for the wheel spacer? Will gen5 Driven captive wheel spacer work?

No It won’t, the hub width is different from Oz to oem wheels. I tried that first and fell short. First call or email an Oz dealer and see if they can get you the spacers, they offered to sell me just the spacer but at the time it would’ve taken 5 weeks to receive. Ended up making my own spacers for the front ROTOR. Used washers and torqued to spec until everything was spaced properly. For the wheel spacers itself I had taken measurements and had them machined by a member on here. Sorry this doesn’t help much bud but if I could do it all over again I’d just order from Oz and be done with it.

Is there anyway you can measure the new wheel spacer that fit on gen5 for me? I measured the OZ wheel spacer that come with the wheel for gen4 and it’s 21.5mm. Some member on here said add 5mm so that would come out to 26.5mm? I would really appreciate and relieved lot of my stress if I know the dimensions of the new spacer.

i don’t quite remember it being that easy. I’ll get you some numbers ASAP. May take a couple days since I don’t have my bike with me while we are moving into new house.

Any chance you could share a link for the 5mm brake rotor spacers please?
