Just got done pulling the studs/pins out of a stock gt wing for a 3m install job. I’ve got a clean trunk, so I’m not drilling 8 (or however many) holes in something that tape will hold lol.
not the cheapest but one of the better looking adhesive only ones, steeda q spoiler uses 3m tape and a 3m sealant, had if over a year. Had it at triple digit speeds and have taken it to the track and it's not coming off
