I wanted to freshen up the look of my 545i. I saw some people had these installed. Any of you guys can suggest a good quality product from a good seller on ebay or a site to buy from. I am looking for M5 style rear lip spoiler. Do they come in soft bandable plastic, thick rubber like or is it like fiberglass? My buddy bought S line Audi lip spoileron ebay and it was very soft and fit good on the trunk. Also I saw Hamman Style front bumper spoiler. Looks very nice. I saw them on ebay pretty cheap, how are they? I was going to have it fabricate it into the bumper, not just glue it on and some bolts. Any help would be great..
