197 spoiler adjustment

Hi,
the spoiler on my f1 is just near-touching the roof, whenever u go over a speed bump or catch the wind it knocks on roof. Is there any way to adjust it so it sits higher, does anyone else have this problem cheers
 
The 1*2 guys use washers/grommets to raise the angle of their spoilers, but if you have the cup spoiler it sounds like a fitment issue.
 
If cup spoiler, slacken off the screws and bolts. Put pillow between spoiler and the roof in the middle to raise the spoiler up. re tighten screws and bolts, remove pillow. Should sit perfect.
