mounts is the exact same as a factory TT - since my cars were originally factory TT's before conversion. I currently have OEM spoilers on my cars that fit perfect so I assumed that the Ionic spoiler would fit the same. Didnt mean to throw you into the fire - was just conveying my experience with the product. As for contacting you, I have always found that places that sell aftermarket fiberglass parts have a stipulation that the parts will need to be sanded and formed to fit right and that they are not returnable. If your policy is different then i apologize and should have called.
