I want to install a rear lip spoiler on my 2003 350Z such as the kind supplied by www.stewartdesign.biz - I want to know if anyone has any experience with this company and if so how it went. Also, if anyone has bought a lip spoiler from them, can you tell me how it fitted - does it fit nicely and is it attached with tape or is it bolted on? The price seems very reasonable and they offer free delivery within the US.
