Snow chains won't fit on 18" wheels. (If I'm not wrong)
And again, depending on the front rotor size, the front blue caliper have different part numbers.
Braking power is about the same for 340/345 and 370/345. The larger rotor just looks way better with 19" or 20" rims.

Ah okay. Well I've got 18" and don't plan to ever change that. Would 340mm look too small? Also when I look at:

I don't see 370mm listed?
