I ended up buying the conversion parts from Precision Porsche. Tony Ugas was very helpful. I went with the Turbo look bumper and T/A sideskirts (like the Boxster in the picture) I also used a combination of 2 different wings. All together the parts cost about $2000. I fittted the parts and they are in the body shop being painted now. Paint is costing another $800.
I'm doing all the labor of fitting and instaloing once painted. I'll post pictures when I'm done.
