Okay, so the website says:
MRP ALSO OFFERS OEM DISK BRAKES USING THE OEM NUMBERS FOUND IN THE REPAIR MANUAL SECTION.
So I type in the search bar:
45121-LDB5-E00
And I get back 4 results with these varying prices:
$63.80
$85.20
$4.35
$66.92
All are 58x4, but with a different overall diameter, so maybe this is not important???
Anyway, did you see that 3rd price, what is that "DISK FRONT BRAKE MATRIX"? I gotta know, lol. It won't let me post the link to the search results page right, but here is where I typed it in:
