Same, it's like my thread has been deleted and merged with an already-existing thread!
My original question was:
If I'm changing the 15" alloys on my '06 147 to 17" Supersports, will I need to be worried about anything else or can I just change them over and start driving?
You'll find the car looks like it's on stilts.
But, other than that it's a straight swap. Some wheel designs came with different length wheel bolts, I don't think your swap would be affected, but it's worth checking you get a good 8-10 turns on the bolts at least.
