soo im looking into the asm overfenders. i have two questions about them....

1) how are they mounted? is it double sided tape or rivets?

2) is it possible to trip the quarter panel under the overfenders to accomodate wider wheels?

 

They use rivets but you need to cut a portion out of your quarters before you rivet them on. It's usually a non reversible process so make sure that you really want them and are willing to sacrifice messing with the stock quarter panels.
