Hi, I have a 318 convertible with the standard 16" style 45 alloys with 205/55/16 tyres. I am wanting to fit the MV2 18" staggered wheels with 225/40/18 on front and 255/35/18 on rear. A couple of questions
1, will this affect the speedo reading by any discrepancy, if so by how much
2, will they fit straight on without any problems
3, I have heard that they may need longer wheel bolt, is this correct
4, Any other issues I may encounter
Advice greatly appreciated
