As above I have never attempted fitting a spoiler before can someone advise me. The lining up and drilling part is straight forward its just the basic sealing process I need to know, surprised coudnt find any info here. There are 4 threaded bars that will go through the boot so do I jus go for a nut and washer the otherside and plenty of silicone? Plus as the carbon lip is hollow water will get underneath it will that cause future problems? How have you guys fitted yours?
