Has anyone used a Gtech Pro and if so, are they accurate?
I have not tested it on a track, but have used it a fair amount on the road.
I used two-inch masking tape on each end of the trunk, and where each of the 4 bolts would line up. (approximately) Since I did it myself, held the spoiler to one side of the trunk, measured carefully, and split the total, which gave me equal distance on both sides. Then pressed gently on the tape. U want to make sure u line your spoiler up approximately with the tops of the rear tail lights.
This left indentations on the tape which I then drilled out. Rubber gaskets on the outside, a little caulk and your good to go.
Had to remove the trunk liner, 10 snaps, two hidden screws in the lining, (on each end) and removed the two trunk handles. Bought bolts at hardware store.
Start to finish 1 hour.
Good luck
Hope that helps.
