Any more news on the sizes and offsets for the RKR's? The sizes seem to vary for different countries.

Also the Kyusha's? They look hawt 8)

In the USA I notice they have 17x9.5-10 for the rota rk-r.
Anyone know if we can get the -10 or lower??

Here's my rota question:

Why are the RBX's made in 17"? The most popular Zed watanabe set up under flares is 9.0" front 9.5"rear, but 16" diameter. If they were 16" instead I would have bought a set.

Much larger and cheaper tyre selection.

Much larger vehicle selection as well. 16" is a bit of an orphan size when it comes to wheel selection.

yeah, makes sense... I guess... it's not impossible to find 16" tires though. And everyone knows that zed's and watanabe's are like cookies and cream so if you gonna rip them off you might as well do it properly.

Yes they fit with stock suspension. I think backspace is 4.75"?? Could be wrong..

Flares are needed for these wheels. Although I have seen a 9" on the back with stock guards, but 9.5 no chance!

Quick answer NO. 8.5" +20 gives approx 5.5" of backspace and the stock suspension is only good for 4.5" on the front of a 260z. A 8.5 +4 would work but it is going to require lip rolling on the front - the rear of 2+2 has a little more room than a 2 seater so they might fit without mods but that is just a guess.

So has anyone got photos of Rota RK-R's on a 240z? In 17" since that's the only size available it seems?

I have always wanted Watanabe's but if you can get almost the same thing for a fraction of the price I'd seriously consider it.

Well I am working with the local agent here in NZ on a set of 15x8 RK-R right now - I will hopefully be getting a rim to test fit and see if they clear the 12.19" Wilwood setup on the front of the 260z race car. So I might have photos (no tyres) of a single wheel in the next day or so.

Hi i was wondering the best offset for rota rims to fit under stock 260z 2+2 no coil overs just 1.5" lowered

Id like to have no mods but guard rolling would 17 8.5+10 front and 9" -5 rear with no flares ?

Or would 8"+5 be a better fit?

I have a set of 18x8 1/4" wheels with a -2mm offset if you want to see what they look like and give you an idea of where the extra width will sit. No tyres mounted on them at the moment, but the final fit and whether you have enough clearance will depend on the final tyre size you ant to run.

They dont make a +5 in the RB only +4.

16x8 +4 will fit front and rear with 225/50s but you will need to roll your back guards.

I wouldnt go with +10s on a Z when there are better options. http://forums.hybrid...hat-size-tires/ here is a guy running the 17x8.5 +4s and they fit fine. Amazing what you can find when you search the internet?  :o


I'm going to say you arent going to be fitting 9" rears on with -5 offset. If you read the post about backspace i wrote in this thread you will be able to work out if it will fit but im 90% sure they are going to stick out. On top of that chances of running a 9" rear without coilovers is pretty much 0. In saying that im only experienced with 2 seaters so maybe the 2+2 will - maybe it's time to research it a bit yourself...

Stiva's 260 coupe is running 15x9's at -10 with stock struts I believe. But the 17" rim might fit a little different.

I had a little bit of a measure this weekend on my 2+2 that sounds to be lowered the same as the one described above.

Its worth noting that I'm looking at Rota Shakotan 15x9's in -10 offset (also available in 0 offset and 15x8 in 0 offset) and I measured (through the spokes in my existing rims), from the face of the rear brake drum, out 124.3mm (as best I could with a steel rule) which from my limited understanding should be how far out the wheel will sit.

I.E. 9" rim = 228.6mm.
the centre of that rim will be 114.3mm (+0 offset, right?) therefore -10 offset would have the rim 10mm further away from the car, meaning:
114.3mm + 10mm = 124.3mm from the hub.

Am I right? or have I got it all arse-backwards? I am a drummer after all, I usually only count to 4  :-[

Anyway, by my - probably shoddy - mathematics this wheel will just fit in the rear guards of a 2+2. The fronts might be a little tight.
As for backspace, I'm yet to measure that. That may be another story  :-\

It's a shame the Shakotan doesn't come in any higher offsets than -10 (or do they?) a -20 or so would do the trick and fill out flares properly, -10's look like they wont.
