Alright, let’s talk about that time I got obsessed with making a NASCAR-style rear spoiler. Wasn’t for a race car, mind you, just for my old beater in the garage. Seemed like a fun project after binge-watching some races one weekend.
Getting Started – The Idea
So, I saw those massive spoilers on the stock cars and thought, “How hard could it be to make something that looks kinda like that?” Famous last words, right? I wasn’t aiming for aerodynamics or anything fancy, just the look. Something sturdy, angled, you know the vibe.
First thing, I went dumpster diving at a local metal shop. Well, not literally dumpster diving, but I asked if they had any scrap aluminum sheets. Found a decent piece, not too thick, not too thin. Paid next to nothing for it.

The Messy Middle – Building It
Back in the garage, I laid the sheet on the floor. Didn’t have blueprints or anything, just pictures I’d saved on my phone. Eyeballed the whole thing.
- Cutting: Grabbed my jigsaw. Man, cutting sheet metal, even aluminum, isn’t clean. Edges were rough. Had to spend ages filing them down so I wouldn’t slice my hands open later.
- Bending: This was the tricky part. Needed that specific angle. I clamped the sheet between two pieces of thick wood and basically just leaned on it, trying to get a consistent bend. It wasn’t perfect. One side was slightly steeper than the other. Looked a bit wonky up close.
- Supports: Then I needed to figure out how to mount it. Cut some smaller L-shaped brackets from the same sheet. More cutting, more filing. Drilled some holes in the main spoiler piece and the brackets.
I remember thinking halfway through, “This is going to look terrible.” The cuts weren’t perfectly straight, the bend was uneven. But I was too far in to stop.
Putting it On – The Moment of Truth
Okay, time to attach this masterpiece to the trunk lid. Measured about fifty times, drilled holes in the trunk. Felt wrong drilling into the car, but hey, it’s a project car, right? Bolted the brackets on first, then the main spoiler piece.
Stood back and looked. You know what? It wasn’t half bad from a distance. Definitely had that aggressive look I was going for. Up close? Yeah, you could see the imperfections, the slightly uneven angle, the rough-ish edges. It wasn’t a pro job by any stretch.
Took it for a spin around the block. Didn’t notice any difference in handling, obviously. Pretty sure it did absolutely nothing for downforce. Might have even added drag. But driving around, seeing that shape in the rearview mirror, it felt kinda cool. Like I’d actually made something and put it on my car.

Final Thoughts
It stayed on there for a few months. Got some laughs, some compliments, mostly confused looks. Eventually, I took it off when I was prepping the car for paint. Still got the spoiler piece hanging on the garage wall though. Reminds me that sometimes just diving in and trying stuff, even if it doesn’t turn out perfect, is worth doing. It’s how you learn, right? Made me appreciate the engineering that goes into the real NASCAR parts way more, that’s for sure. Those things take a beating; mine probably would have flown off on the highway.
