I have the Five Axis spoiler and i love how it looks. IMHO don't buy the eBay replica, it doesn't come with tape. The real 5 Axis comes with an install kit made by 3M with adhesion promoter, and install templets. Great sep by step install guide also. I bought mine unpainted for $230 and my work painted it for me no charge so i saved on the paint charge. Spending $350 for it is a bargain when you see the quality. The body shop teacher who painted it said it's very high quality.
I bought mine from
3dcarbon.com you have to call them to buy just the spoiler.
