Actually, I have been digging into the trunk layout specs and load shifting is a legit safety issue on steep inclines like yours. Honestly, Im satisfied with the Husky Liners Uni-Fit Cargo Mat 41x30in because the TPE material has amazing grip. It basically locks items in place so they dont slam into the trunk lid when you are parking. For a net, the TrunkCargoNet.com Envelope Style Trunk Cargo Net for Mitsubishi Mirage G4 works well because it uses heavy-duty bungee cords that keep their tension better than the cheap generic ones. I have no complaints about the reliability of the clips either. It keeps your center of gravity low and prevents things from tumbling. Definitely a more stable setup for a small car like the G4... makes it much safer.

Honestly, I tried to go the cheap route with some generic plastic bins from a big box store and it was a total mess. Unfortunately, they just slid everywhere the second I hit a hill, and they actually scratched up the side panels in my G4. It was way more frustrating than I expected and honestly not worth the few bucks I saved. I finally gave up on those and tried something with a bit more grip because the trunk floor is surprisingly slippery.

• Use WeatherTech Cargo Liner Custom Fit to keep the carpet clean and add some friction.
• Look into Drive Auto Products Car Trunk Organizer with Straps because the tie-down straps are essential for that steep driveway. Quick tip tho, make sure whatever you buy has a rubberized bottom. The carpet in these cars is pretty slick so anything without a grip is just gonna be a projectile the minute you park... its kinda annoying how much stuff shifts back there.

Works great for me

In my experience with smaller sedans, a net is a total lifesaver. I've tried many setups over the years but honestly, getting the Mitsubishi Genuine Parts MZ314815 Trunk Net is your best bet because it fits the factory mounting points perfectly. For grocery bags, a Fortem Car Trunk Organizer Collapsible is super cost-effective too. It basically stops everything from sliding when youre hitting that steep driveway. Youll love the extra stability.
