Not in the 328... the rotor size in the 328 is smaller...
Not sure what the rotor size for the 228 will be... but you might get bigger rotor in the 228 if you get the upgrade

Also, FYI be weary of pricing 
228i
36,000
1,500 (leather)
2,000 M Sport
1,500 M Performance
850 adaptive M
~42k and I think the M235i has some other things as STD
Edit: I could be wrong. Got this from another post, I am sure it applies
