I recently purchased my Ti. Grey strakes from rx8strakes.com. They are slightly crooked on the car just using the screws, and I was wondering, if I use the double sided adhesive tape they gave me, will I be able to take off the strakes in the future without damaging the paint??

 

yes,
and i used a little black silicone glue on the plastic vent.

Adhesive tape isn't going to damage the paint. You will just have to heat it up with a hair dryer when you want to take it off.
