I mounted my R1 spoiler today, but only mounted the 4 outter screws. Obviously, I still drilled holes for the inner studs, but didn't take of the interior moulding to afix them. My question is, does anyone know what size the nuts are that go on those studs? My spoiler didn't come with any hardwar. i bought and figured out that the screws were M5's but never did get nuts for those 2 studs. So does anyone know the size?

 

Just go to a hardwear stor wit the car and test the nuts on it. Find one that works and wolla.

 

I could, but since I already mounted it, I would rather just know what size to go buy and not have to take the spoiler back off again.
