Ok so I totally feel u on this. The CT4 trunk is lowkey a struggle because of how narrow it gets between those wheel wells. Honestly, I went through like three different setups before finding something that actually stayed put when I'm taking corners a bit too fast lol.

For your situation, I would suggest looking at these specific ones that fit the Cadillac dimensions perfectly:

- I've been using the Fortem Car Trunk Organizer with Straps and Non-Slip Bottom for about a year now. The best part is the securing straps—you gotta hook them to the cargo nets or tie-downs so it literally won't budge.
- Another solid one is the Drive Auto Products Car Trunk Organizer with Reinforced Straps. It's a bit more compact so it doesn't eat up the whole floor, which is huge in the CT4.

Just make sure to use the velcro on the bottom too! Serious life saver for those grocery runs. gl!

Respectfully, I'd consider another option—skip the bulky bins. I tried that in my CT4 and the weight distribution was *awful* on sharp turns. Honestly, just get any of the cargo blocks from WeatherTech. They use a grippy plastic base that handles lateral G-forces way better than Velcro on our specific carpet. Basically, keeping it modular is way more efficient for that narrow trunk layout. 👍

Ok so I went through this exact same thing last year after picking up my CT4. Honestly, I'm a bit of a data nerd when it comes to cargo dimensions and it really is a narrow fit—basically only about 37 inches between those wheel wells. I spent way too much time measuring because I didn't want to spend a ton of money on something that wouldnt fit flush.

Basically, I wanted something budget-friendly that actually maximized that specific width without sliding. I actually ended up trying the Honey-Can-Do SFT-01166 Trunk Organizer because it's only about 25 inches wide, which leaves just enough room on the sides for a gallon of milk or my detailing spray. It was only like $15 or $20, so I wasn't expecting much, but the technical specs on the grip are surprisingly decent.

I was worried about the sharp turns too, so I actually added some VELCRO Brand Heavy Duty Tape 2 Inch x 4 Foot to the bottom of the bin. Since the CT4 carpet is kinda dense, it hooks on perfectly. Now, even when I'm taking corners a bit fast, the bin literally doesn't budge. Idk if you want to go the DIY route, but for under 30 bucks total, I'm super happy with how it turned out. No complaints so far!! maybe that helps? peace

I would suggest being really careful with loose cargo, honestly. I learned the hard way when a heavy glass bottle shifted during a sharp turn and actually scuffed up my interior trim—so annoying to fix! Safety and stability are huge in a car that handles as well as the CT4, right? You dont want weight shifting unexpectedly mid-corner.

Here is what I recommend for staying secure:

* Rola 59001 M.O.V.E. Rigid Base Trunk Organizer: This one is basically a tank. It has a non-slip bottom that grips the carpet like crazy, so it wont slide when you're cornering.
* Lusso Gear Heavy Duty Car Trunk Organizer with Adjustable Straps: This is great because it has actual safety straps. I always clip mine to the factory tie-down points just to be 100% sure it stays put.

Basically, you gotta make sure whatever you buy has a way to anchor it. Don't risk the interior damage!! gl!

Jumping in here because honestly this trunk is a total nightmare. Ive been driving these cars for decades and this layout just makes me want to scream sometimes. Its so narrow that even the expensive stuff looks like junk once you try to jam it in there. I'm really cautious about these high-end suggestions because half the time you're just paying for a logo and it still slides around. It makes me so frustrated that we even have to spend extra cash just to keep a gallon of milk from exploding.

• Honey-Can-Do SFT-01166 Folding Trunk Organizer is way cheaper than those boutique brands but might be too flimsy
• Be careful with the AutoDrive Collapsible Trunk Organizer since the sides are kinda weak for the price
• Dont spend over thirty bucks honestly, its a rip off Ngl, it really feels like Cadillac forgot people actually buy groceries with these things. Just make sure whatever you get has some grip or it's gonna fly mid-turn... such a headache.
