The Chargespeed Roof Fin is a really good product. I purchased in FRP, as prefer the painted look, and wanted it to be seamless. There were a few rough bits on the part, mostly the fins, and also where the fibreglass meets the plastic - could have been finished a bit neater/smoother, but nothing a bit of putty and sanding can't fix - overall the quality is strong. The packaging of the product was awesome, as it was really well wrapped up. Most importantly the fitment is 100% excellent!! (no gaps at all). On top of all this pricing at Japanparts is really competitive and you'll get a great deal. If you have a Subaru Impreza/WRX/STi, then I'd highly recommend this Roof Fin.

The Chargespeed Roof Fin comes well equipped for installation - it has tape, glue, and 4 x screws. Personally, we chose to use the same glue that panel shops/smash repairs use, as this has multiple benefits. It will never come off or get loose; it cannot be broken or easily lifted off, therefore cannot be stolen; and it saves drilling holes in the roof. Just glue, position, press down, and use panel shop tape to hold until dry; then remove tape - will sit flush and seamlessly - job done!
