Volvo sent wrong discs

[silverhorse]

Was just going to change front discs on my V70 2.4 T5 and thought i would measure to check. My car has 316mm and Volvo has sent me 320mm. Will they fit and be OK or will they cause problems?

Should be 320s, 316 and 336 are for xc90s

100% 316mm. Confirmed with Volvo and a while ago bought 316's from Jamie at PFV. Even measured them today

It's unusual although the car you have also has m14 hub bolts to caliper hanger, so you could put on 336s

I've come to the conclusion that my car is a bit weird. I went to Volvo for a new MAF to turbo pipe and my standard 2.4 T5 engine has a lot of R pipes and parts. Had the parts manager scratching his head. And now you say I have XC90 discs!!!
Anyhoo, do you think I will get away with the 320mm's when they should be 316mm?
