Guiding mount time: 0,25 hour(s).
Please note: The standard lenght is M12 X 1,5 X 28MM - that is why we name all wheel bolts "short" when the lenght is less that 28MM - if its more than 28MM we name them "long"!
Per pcs! the lenght is meassured from where the thread starts until where the bolt begins to get conic!
Let one of our BMW specialized workshops do the mounting, we got the know how and low prices!
