Apologies if I didn't send you a link to the full fitting instructions (that normally comes in the box) - there's a bit in there about the screw fixing points.
Glad to hear you're really happy with it!
Wonder how much extra downforce you'll be getting around the track...?

If you have a digital version of the instructions, could you send it to my email please? Just want to compare and see if I missed anything or messed something up in the only way I knew how lol. Info.krylov@gmail.com
