M45 Sport Wheels on an M56

[Big_Tone]

Hi guys! I currently own a 2008 M45x with the 19" sport wheels. I may be trading it for a 2011 M56x. Will my wheels from my 45 fit the 56?

[Ilya]

Yes, it'll be fine. Might not look quite as good (offsets) but you'll definitely be able to install them.

[Debonair]

I could have sworn I saw a pic of a Y51 with the 19" sport wheels on it somewhere.

[Big_Tone]

Really? Will they be more narrow?

[Debonair]

A quick search returned these numbers. I am 80% sure they are correct.

M45 19' Sport Wheels - 19 x 8.5 / 50mm
M37/56 Base Wheels - 18 x 8 / 43mm
M37/56 Sport Whees - 20 x 9 / 43mm

[DoN_BLaZe34]

Those numbers look accurate to me

[Big_Tone]

Thanks for the info! Looks like they're better than the stock 56 wheels, which is exactly what I needed to know

[BlackCat81]

They'll definitely fit if it doesn't have the big sport brakes. I'd imagine they'd fit with them as well, but I'm not 100% sure.

Edit; if it has 18's it doesn't have the sport brakes. Disregard my rambling.

I remember reading somewhere that someone had upgraded their M35 or M45 to the Akebono calipers and had to use wheel spacers for the 19" sport alloys to clear.

[DoN_BLaZe34]

Correct, when I had the Akebono's on my 45, 15mm spacers made the sport 19's clear the caliper.

All of this is null and void since he's getting a 56x which won't have the sport calipers lol.

Actually I have seen M56x with the Akebono installed from the factory. But here is an example:

Correct. The M56xS, like the one in your link, have them from the factory, the M56X does not. OP is looking at a 2011 and the "S" version of the M56 was not offered until 13' (I think).

That car is a 13 56xS so it has the sport package along with AWD. That's outside of what I was speaking to.

The OP mentioned he was getting an '11 56X which doesn't include the sport package, hence my statement. Infiniti didn't offer the sport and AWD combo until the 13 Y51.

Even if the OP's 11 had the sport brakes from the factory, his car would've also come with the sport 20's which again would make this entire convo null and void lol.

So with my M45 sport wheels having a 50mm offset, am I to assume they will sit wider than the factory M56 wheels that have a 43mm offset? Or do I have that backwards?

According to the chart provided by Debonair, the M37/M56 20" Sport alloys are wider and sit further away from the wheel hubs. This gives the car a much better stance and also more clearance if you ever do decided to upgrade your brake system to the Akebono calipers.

A quick search returned these numbers. I am 80% sure they are correct.

M45 19' Sport Wheels - 19 x 8.5 / 50mm
M37/56 Base Wheels - 18 x 8 / 43mm
M37/56 Sport Whees - 20 x 9 / 43mm

[Big_Tone]

Thanks for your reply. What I'm comparing is my M45 19" sport wheels with a 50mm offset to the factory M56 18" wheels with the 43mm offset. Will the 7mm differential between the two sit the M45 wheel closer to the car or further away?

[DoN_BLaZe34]

The 45 19's will sit closer to the car

[Big_Tone]

Ok thanks. I may be better off with the M56 factory wheels and upgrade at a later date then. Thanks everyone!

[Debonair]

It should be a 7mm difference.

"Package 2" is the Y51 18" wheel.

[Big_Tone]

It should be a 7mm difference.

"Package 2" is the Y51 18" wheel.

Thanks for the info! The more I looked at it the more I liked how the stock wheels looked compared to my old M45 sport wheels. I may consider upgrading to the 56 sport wheels at some point, though

Hi all,
I have a '13 M56xS, I test fit my '19" M sport wheels are requiring spacers. I was looking online and the 12mm don't get bolted on the 15mm ones do.

Has anyone done this? If I use the 15mm do the wheels clear the stock bolts.

If I do the 12mm spacer could I use the stock lugs?

Thanks

Andy

So I put the 15mm bolt on spacers and the wheels clear, barely, Ok just like the stock clearance from the factory with sport brake package. I'm using the 19's for snow tires but may sell them due to how expensive 19" snows are.

The wheels have the hole in the inside to clear the factory lugs and studs to clear.
