Cutting interior trim
I have installed the Silverhorse racing louvers and I am now at the part where I must trim down the interior plastic parts. It is recommended I use a jig saw but I am nervous about cutting them. Any advice on how to make this easier would be appreciated.

Another member used a utility knife to cut his bumper for the quad GT500 valance install - I would think the interior plastic is thinner than the bumper urethane, so you might try that. If not, dremel.

How thick or fragile is the material? Whenever I cut plastic I prefer to carefully score the part and then snap it. It makes for a straighter, cleaner edge.

I used a dremel for the rear bumper when I did the quad exhaust mod. It worked well using a wheel designed for plastic. I did have to smooth the edge after cutting a bit, but that was easy to do.

I have cut panels on other vehicles for stereo installs, and I would definitely use a dremel, or even an air-powered cutting wheel (like a big dremel), if you have a compressor.
A jigsaw would work, but I think would be VERY hard to manage on a curved and three-dimensional part - you would have to clamp the panel in some sort of vice in order to cut it precisely, I would think. The dremel or cut-off wheel will be much easier to manipulate, although you will potentially sling melted plastic on yourself (been there... LOL)
No matter what - it will be important to mark the cut lines very carefully, and very well, so you can see them while using the tools. My advice, do not use tape to mark, as it may not stick well, especially when you start cutting. A pencil may be easier to see than a sharpie, and a trick that I have tried in the past - if you are marking and cutting on the back-side (that will not show), you can spritz a little primer or white paint on it, just enough to have something you can write on that will show up a pencil line or sharpie line - better than the bare plastic.
Also, get some sandpaper, or a file, so you can smooth the edge - do not try to do that with the dremel or cut-off wheel. Wrap the sandpaper on a paint paddle, or small/flat wood block of some sort.

I finally started cutting using a Dremel with a quick lock bit and wheels made for plastic. So far so good, actually really good. The 2 parts I was most worried about are cat and installed. Now for the straight flat bits and the install of those.

Alright. Everything is back in... Sort of. For some reason I can't get the passengers side door plate clips won't seat correctly. But it's drivable. If there wasn't so much snow on the roads.

Did the clips separate from the sill plate? I know the metal clips have a tendency to pull off the will plate and not hold in correct. What I had to do with was pry the metal pieces out of the body and reattach it to the sill plate to get it to hold in place. Do you have any photos of what you had to trim, or what it looks like from the inside?
