For what it's worth..
I have a set of "15 AMG monoblocks (copy of AMG), for winter tires. And a similar set only in "17 for summer tires.
The "17 requires 10 mm longer bolts that the "15.
Be careful not to get too long bolts!!
I thought i was really clever when i used the long bolts for the winter tires. -They totalled the internals of my hand brake (the drum brake part of the combined disc/drum brake system), because they were sticking too far through!
Never criticize someone until you've walked a mile in his shoes. That way, when you do, you're a mile away -and you have his shoes!
