I have the M3 kit on my car installed from their shop and its great. They Garantee their work 100% so if it does crack or anything they will fix it. But I've had no problems with the fiberglass. They matched my diamond black paint perfectly. As for the reiger kit they just got it, and they are installing the first one on an e36 convirtible. So Ill get some pics in a week or 2 when i go back to the shop.
