One of my friends has the Hamann front lip, it actually looks really good. It came with his car when he bought it and I have no idea where you can find one. They're not even listing e36 products on the Hamann site any more.
"Driving is like a narcotic, an addiction that can take over lives. It ruins people, breaks families apart, and even kills. Itís habit that needs to be fueled.
