That was one of my wonderings......no ideas unfortuantly, havent given it much more thought 
Id say no, as the bumpstops sit at the top to the strut and will only come into contact if the suspension is compressed enough, if the car was lowered by 35mm then removing 35mm from the bottom of the bumpstop ultimatly lets the suspension move that extra before it bottoms out.
Having said that, lowered suspension is also uprated, so i figured it would have less chance compressing that extra 35mm anyway......and as i said above i didnt cut mine, as i thought id see what happened and then uprate if need be.
