I've started work on the rear fascia. In order to perform the "diffuser fascia" mod on the new fiberglass fascia, I decided to take a casting from the old one. The original mold (which was made from scrap wood and styrofoam) has deteriorated to the point of being unusable.

Below, you see a shot of the rear fascia being prepared for the casting process. I used several coats of parting wax, and a couple coats of PVA film.



24 hours later...



I was a little surprised. The casting actually started separating from the fascia on its own! Removing it was quick and easy. Here's what the raw casting looks like.



The next step will be to chop out the appropriate area of the new fascia, and use the casting to mold in the new diffuser section.

I don't think I mentioned this before, but my aftermarket wheels didn't come with centering rings. So I was relying on the wheel studs to keep the wheels centered. That wasn't working out so well. I got tired of my wheels getting knocked off-center when I hit potholes and stuff.

I asked a local club member to make some wheel centering rings for me. Here's what I got:



They're machined from aluminum. I installed them today, and they're a perfect fit. Thanks, Marc!

I've made some progress on the new "diffuser fascia". The casting I mentioned earlier was used to mold the diffuser section into the fiberglass fascia. Here are some photos of that.

First of all, I marked the area to be cut out of the fascia. The red line shows where it will be cut. (the fascia is upside-down)



And here it is after cutting.



Then, I molded in the diffuser section. The photo below shows the new fiberglass fresh from the mold. It's a little rough at the seams.



After some sanding and smoothing, it looks better.



The next step in the project should be deleting the molding. That was the whole point of using the fiberglass rear fascia. I can grind off the molding and use fiberglass to fill the voids, with no worries about it falling apart.

I'm also considering a couple other tweaks, but haven't made a final decision yet.

I just realized it's been 6 months since my last post. Wow, how time flies.

I haven't made any major changes or upgrades since my last post. But I've done a lot of small things. Some examples:

-- Install stainless fuel lines from the Fiero Store
-- Upgrade to 19 lb/hr fuel injectors
-- Upgrade to MSD Blaster ignition coil

Oh, and I've been driving the car a lot.
