OK I just finished this and it wasn't as hard as expected.. Anyone interested - read on..

Ended up getting a great deal from a fellow fit-freak member on his OE Sport spoiler - same color but no bolts/hardware. Got it today and it was in great shape.
1) Get a dremmel with a cutting wheel that can cut thru steel and dremmel off the 3 center-studs on the OE spoiler. I put some painter's tape all over to make sure I didn't scuff up the surrounding areas. Get a REAL dremmel - I had the small 4.8v rechargable one from Walmart and I had to charge the battery TWICE to get thru the 3 studs.. Very frustrating... 2) Once done, I lined up the spoiler and placed 3 strips of painters tape to hold the spoiler to the roof and centered it. 3) Once centered, center-punched hatch-area where the mounting holes were to be drilled. 4) Removed spoiler from car and drilled the 2 holes. I started off with a 7/16bit then progressed to a 1/4in hole. Make sure you mask the area for any metal shavings. take your time. Each time too many shavings appeared - I used some painters tape to sticky-pick-up the shavings and started again. You need to remember to remove the 2 rubber grommets (one on each side) on the top-underside of the hatch. Drivers side = has wiring running thru it. Pass side = nothing. Make sure on the drivers side you move any wiring/washer-hose out of the way prior to drilling. You'll be able to tell where it'll push thru as you'll feel the dimple from the center-punch.5) Opened hatch and layed spoiler across to line-up bolt holes. I lined the front side of the spoiler with 3m molding tape and peeled a small area off and taped it so I could peel it back once the spoiler was on. 6) Used a 1/4X3/4 bolt with a large top-washer. Fed it thru the hole. Peek thru the grommet hole and you'll see where your bolt is. Got a nylon-self locking nut and taped it to my pointer finger. I did this as no way you're going to fit TWO fingers into that grommet hole. I taped it so that I could start-threading on the nut/bolt. Once it started - I pulled my finger out with the tape. Sounds funny but it worked like a charm! 7) tightened both bolts on each side snugly - just enough so that you can adjust it a little - center it up and pulled back the red-layer of the 3m tape. 8) Apply pressure to the front of the spoiler then opened up hatch to tighten down the bolts a final time. Not too tight! 9) reinstalled grommets and closed hatch. 10) Made some reference marks on the top-bolt-heads to make sure I could tell if the bolt was moving/loosening up later on down the road. snapped the bolt-covers on and all-pau.

Wiped down the rear with a microfiber towel and polished up. MAN does the spoiler make a difference on how this baby looks. Also got some 15x7 Maxxim Screech's with the black inset + polished lip... Aaahhhhh. All done.. Hope you found this helpful - let me know if I can be of assistance.

 

Funny 'cause I love how the Fit looks without the spoiler, but that may be in part to that I have the Sport model so with the lip kits it doesn't look so bland.

Nice write up though!

 

Getting ready to do the same thing with a used spoiler. Any pics before during or after.

do you have the lip kit? or did you install spoiler not having the kit... i'd like to see some pix as well.

 

I talked to the dealer today (parts person) their is not kit for the spoiler, the hatch is a different part number. The plastic inserts are available but the metal nutsert / rivnuts are not available (the one at each end of the hatch for bolting down the spoiler).
I think I can do what is described above with a locknut, I might get the plastic inserts too while Im at it.

 

i hope the install goes well. thanks again for buying the spoiler

 

I'm sure it will and thanks for all your info and help. I'll take pics when I do it
