If you're interested, come by and let's take a stab at installing them. I'm not a mechanic, but have taken apart and put together my S2000s, BMW's, and other cars quite handily (and have a bevy of tools to do it). Otherwise, I'd recommend taking it to A&L Autobody in Palatine. They work on Porsche's, Ferraris, Maserattis, BMW's all day long. Talk to Anthony and let him know Urmil sent you.
And, having done it myself on my car, I'm happy to answer any questions about my installation experience (and provide pics of my install if you need references regarding hte quality of my work, lol).
