Alright all done installing the HFP rear under spoiler and it was kind of a bitch lol but all went well.
Removing rear bumper was extremely easy
Took everything inside was about 15 degrees when I started early morning
Drilling in the wholes was very easy everything is already marked by Honda from factory all you have to do is drill 10mm holes, 10 in all and install as followed by the PDF file you get from CollegeHillsHonda. The thing that worried me the most was actually cutting the exhaust piece. But it's already marked again from factory where exactly you need to cut. Instructions said to use a Hacksaw but I just used my Dremel
My only suggestion is before bolting everything up is to be very careful with the black trim you see in the pic if you aren't careful you'll bend it in and have to take everything apart and align it back up.
With everything done was easy putting the bumper back on and it came out great. Love the HFP kit a lot cheaper the Mugen and I think it look's damn good sets the car off just right and it's so subtle.
Thanks for looking
