Hey guys, I received some project kics wide tread spacers as a gift and need help finding out what size they are (20mm, 25mm, 30mm). The labels are in japanese. My brother bought them off his friend who has a STi and both of the boxes' labels indicate this:

 

Why not just open the box and measure them if you are that unsure?

...they are 30mm

 

That would be harder than taking pics and posting them.

 

Just measure the width of the spacer with a ruler. Use these specs to find out what size they are...

1.18 INCHES = 30 MM
APPROX. 1 INCH = 25 MM
0.78 OF AN INCH = 20 MM
.393 OF AN INCH = 10 MM
0.197 OA AN INCH= 5 MM

It should take all the guess work out of reading all the jibber jabber on that box you got there...

 

Would using a ruler be too obvious?

 

Are Japanese millimetres different for US millimetres?

 

thanks guys
