86/BRZ GT-WING NEO、GT-WING ALMINIUM2 is on sale now (in Japan).
Sorry for the late update ^^;
It could use the original installation hole, if the car has a original wing.
And also we provide the horseshoe shape stay to increase the strength fro the truck.
Plus, if your car has no original wing, we can give you the FRP stay to punching a hole for FREE!
Please let me know if you have any questions and purchase order♪
