My Japanese is a little rusty..

What does number 4 mean?? Is it just retorque after 100km?

[ck_chino]

I would have to agree with ur guess as well, thats good practice to re-torque anyways

[MarusGTR]

It's a spacer? Definitely retorque at 100kms to properly seat it in.

BTW, wtf are they using standard units!?

[coston]

They're lug nuts. Unusually do check tire pressure and re torque often. Just not sure if that's what the picture actually means haha

[Daryl @ RightDrive]

Yes, it says to check them again after 100kms.

[coston]

Thanks Daryl! My second guess was after 100km your car will magically levitate.
