Just did one on my buddys TT Cobra a few months ago. Simple.
1.) Ull need a 10mm rachet.
2.) Open trunk and remove the 2 plastic plugs, thats where 2 of the bolts are.
3.) Remove the two lower bolts on both passenger and driver side first.
4.) Tilt the wing forward and remove the other two bolts. Don't let it fall, have someone help u.
5.) Close trunk, remove spoiler.
