I could go either way with this, I wasn't going to get involved in this thread, but not a day doesn't go by where I don't wish I had skirts on my car. Seeing the last group buy explode does not do much for confidence and I see there are not many from the last group buy willing to take the chance again. As far as fiberglass goes, my vote is for poly and poly only. Fiber is just too ridged and frankly too big of a risk for another group buy. There is too much human involvement with fiberglass and or it takes a lot to fit. Anyone who is going to go $1000 into this trust me you will and to take the extra $400 step for poly. At the end of the day a kit of this magnitude in poly $1400 is a very fair price. Just be happy your not paying brabus or lonsier kit prices.
