You do not need a strut tower brace on these cars. They are exceptionally stiff in the front. The struts are jammed up against the firewall which is one of the stiffest areas in the entire car. It is also right where the very strong A-pillars meet as well. This is definitely one area of the car you don't need more metal in. The Civics from 2006 on are one of the stiffest cars out there in this area as well in comparison to other cars.
Also the area where this bar bolts into place is almost completely hidden by the cowling. If you were just getting it for looks thats fine but if you can't even see it, I don't see it being worth your money in that aspect either. If you are looking for improvements on your car, there are better places to start.
Are you looking to make your car handle better? Have you already gotten stickier wider tires? Upgraded the struts and springs all around? Changed out the rear sway bar?
Just some suggestions in things that will improve your car in a way you can actually notice. It's the same with underbody bracing. Look at the braces the HPD teams run. If they aren't using it, you probably don't need it. There is also a big misconception between cars that "feel" like they handle well and cars that actually handle well in terms of going through curves faster.
If your car had struts that were sitting out on their own in the middle of the wheel well like they were on older cars this might be a something to consider:
