Hello

car is a 55 plate 330d m sport

I have put my vin into RealOEM and it lists two options for the fronts either 330mm or 348mm

is there any other way to tell without taking the wheel off and measuring?

also if they are currently 348mm what will happen if i replace with 330mm and vice versa?

is pagid front discs and pads ok?

Thanks

Post a picture of them is easiest way as the 348mm has a caliper that is about 30cm long lol. The 330mm disc has a much smaller caliper.

Also if yours is an E90/E91 then its very likely to have 330mm disc.

It'll be a 330mm. The 345 goes on 335i and 335d

As above, it should be a 330mm.

330d (245bhp) has 348mm front discs.

Could be either, depends on your caliper which gives it away. If 330mm the caliper is a slim and small thing, similar in design to the rear caliper.

If 348mm discs, you have the beast caliper as seen on 335i and 335d.

I have a 245ps 330D LCI (N57) and it unfortunately has 330mm discs but they can also come as 348mm setup.
