Sorry Rub no such thing as "PERFECT" fitment when it comes to aftermarket fairings
I however did purchase a set of injected molded aftermarket fairings off ebay for my busa and Ive had them on for over a year now with little to no complaints. Matter a fact that's usually the 1st thing people comment is how they like the color of my fairings. Heres my advice to making them work.
#1 ditch the inner dash fairings because they look like absolute chit and don't line up nearly as good as OEM
#2 ditch the belly pan wing and either use your OEM or get an aluminum aftermarket wing off ebay. These fairings look really nice but they are no where near as flexible or as durable as the OEM's so first time you hit a rock/pot hole/ or lip of a garage entrance that wing will crack like an egg
#3 Like I said I ordered mine over a year ago and don't recall the specific company but you have to get the injected molded kit. They are not great but a lot better quality and fitment than the other versions and worth the extra $50 or whatever it costs. Ive seen a set of both and mine were definitely painted better and lined up easier than the other set my brother bought for his gsxr
#4 Set a realistic expectation on how they look and are gonna perform. Your getting a whole fairing kit for basically the cost of 1 OEM fairing so they may or may not line up exactly perfect or have a pristine paint job but its a quick and cheap way to change up the color scheme of your bike without breaking the bank. I still get compliments when I pull up to a crowd of bikes and I cant help but laugh on the inside
thanks for complimenting my knock off fairings.......... For the price its at least worth a try so you can form your own opinion and see for yourself. good luck
