I would probably want to look at having something to hold the centre as well, though it wouldn't take much to have some small hooks which replace a couple of the plastic clips so you can just hook the bumper over them.
The most time consuming bit then would be removing the grill
Id be keen on a set like the top pic. but don't care enough to retrofit a universal kit. if someone put together a kit to fit a VR4, Id buy it!
I hate those rubber band type ones.
nice....But I like the flush look.. id rather take the time to remove my bumper and not have visible bulges lol..but hey ill eat this comment one day when I do order some tho,good find tho..
