DIY: JDM Door Sills

It takes a certain amount of courage to tear apart our luxurious interior,
but even more to cut it ;) You will be doing exactly that using this DIY--tearing and cutting.
Do not worry! It's a cinch; trust me. If I did it, you can too.

1. Remove the top portion of the sill by wedging a flat surface underneath and carefully prying upward:

2. Once the top portion of the sill is removed, the bottom half is next.
Removal is just like step one. Pry from behind as to avoid damaging the paint:

3. Now the top and bottom halves of the sill are removed:
(check out the 12-year-old preparation plastic)

* if you're a neat freak like me, then clean underneath where the sill used to be.

4. Cut out the USDM sills as such:

Notice I cut before the small hump, just after the raised grips.
In step 6, you will bring the cut forward, right at the small hump.
It's easier to do this in two phases to eliminate an accidental screw up.

5. Pull apart the cutout:

6. Now that the main cut is finished, I used a dremel to smooth out the cut and actually bring it forward a bit, right to the small hump, so the JDM sill sits flush.

7. You may need to pull off the mount tabs from the USDM sill
if any slipped off during the removal. If so, do that now and place them
back in their mount holes. Finally, sit the JDM sill in place:

Repeat steps 1-7 for the remaining sill.

I spent more time polishing the sills than I did intsalling them:

Good luck and God speed!

Yeah, and my doorsills are still under my bed after all this time. One day, one day.


Since you're not installing them, how about we rekindle that deal we had going earlier.... ;)

I'd love to sell them to you. But I am attached to then. I actually installed one in my brother's coupe a few months back using this DIY.

I just have to find the time to do it to my coupe. Sorry man, wish I could help.

Wait - you had multiple sets? (pair for your brother and pair for you)?

...I can't seem to find them anywhere anymore... never on ebay anymore it seems.
Nope, 1 pair. Gave em to my brother to figure out how to DIY with an xtra set of OEM plastic sills. When I saw how good they looked installed, I HAD to keep em.

They're never on Ebay anymore. Probably been a year at least since I seen em.

How is it I search for "legend sills", "legend sill", "legend plates" and "legend jdm" every few days and never find a set, then the 1st time I mention on this forum that these sills are hard to come by, someone posts up a set and makes me look like a complete doofus! lol

Well, I bought 'em. Thanks for posting the auction! :bowdown:
:) glad to help
Nice price and condition. Good find.

Octane: If you want to purchase the plastic JDM doorsills that the metal sills originally came mounted on (they are dark grey in color), let me know. If you use them, there is no DIY, just pop em right in. They look good with black interiors IMO.

You have pm!
nevermind about my pics request - I see these are them:
great write up! used it the other day (from memory actually) to install minez :D

Thanks for the input! I installed them yesterday.
I did the "big" cut first, then smoothened out the small hump with dremel.

sills look nice. Now time for new leather ;)
Great and clean work, Istvan
Seems that you have no finished all the work with JDM parts. Parts like JDM folding mirrors, Type II Intake and now the JDM Door Sills. Gee I guess you have spend lot of bucks and work to get it realized. Time to change your Custom User Title to 'JDM KA8 owner' instead of 'EDM KA8 owner' :giggle: Be seeing you ;) -Mike

would i be able to modify these to fit them in a sedan?
no. and to attempt such a thing would be sacrilege.
You guys have some nice Legends! I'm glad all of you found the DIY useful :) These sills look tight, eh? They're a luxurious upgrade.
