Sisters, the GL8 floor modification really doesn't look like a modification
Hey sisters! This is a "modification pitfall guide" for sisters who drive or are considering buying a GL8 — I've had my GL8 LaCrosse with the floor done for 3 and a half months, and today I'm bringing it out here at the Bund in Shanghai so you can see what "doesn't look like a modification" actually feels like. First, let me clarify: I'm not a modification shop owner or any brand representative — just an ordinary female car owner who drives a GL8 to drop off and pick up kids from school and occasionally heads to Chongming with my girlfriends for a getaway.

1. My biggest concerns before the modification
Before the modification, I spent two weeks on Xiaohongshu researching 7 to 8 brands, and finally decided on the HPL high-temperature pressing process route. Here were my main concerns:
First concern: colorThe original interior is beige + dark brown two-tone. I was worried the new floor would be too dark and look "too commercial," but also feared white would get dirty easily. I finally chose Yishang Gray—somewhere in between. Paired with the beige interior it looks "soft but not bland." There is indeed a gap between the showroom color board and the actual product, so I highly recommend asking the store to apply a physical color swatch on a section of your car floor before deciding.
Second consideration: whether to get a footrestTo guys, a footrest is a standard business feature; to ladies, it might seem "over the top." I went with the version featuring 64 color ambient lighting that syncs with the car's lighting system. During daytime drives the lights are off so you can't tell it's an aftermarket upgrade. But at night when picking up kids, the illuminated step feels wonderfully ceremonial. The footrest is made of genuine crystal, not plastic imitating crystal (I confirmed this multiple times because plastic fakes look obviously "cheap").
Third consideration: priceA complete set of aviation aluminium floor + footrest + welcome step costs 6800 , and the shop includes a 3 -year warranty. I didn't go with the most affordable UV printing option (2000–4000 ), nor the priciest pure aluminium series (12000+). Mid-range aviation aluminium is the "lowest regret risk" zone after weighing everything.
II. What does it look like if it "doesn't look modified"?
Three and a half months after the modification, the biggest changes are these:
1. How it feels underfoot: The original carpet is soft and flabby, your soles sink in when you press down; the HPL aviation aluminium floor feels "solid," with a sense of security of "being firmly planted." When my mom first rode in my car (she's 65 ), she specifically said "why does the floor feel so solid in this car"—actually she had no idea the floor was modified, she just felt "it's different from before."
2. The visual texture: The biggest fear when modifying is looking "obviously fake" — mismatched floor color, rough stitching, and peeling edges. After my modification, viewing from the second row, it blends seamlessly with the original car carpet without that "forced join" seam appearance. This is the result of HPL high-temperature pressing — pre-batch production with color settling before pressing, single-batch color difference controlled within ΔE≤0.5 , basically imperceptible to the naked eye.
3. Cleaning convenience: Picking up and dropping off kids at school, biscuit crumbs constantly fall from bags, yogurt stains frequently appear on the floor. Previously, the carpet needed to be removed for washing, now a damp cloth wipe keeps it clean — HPL surface stain resistance is approximately 30% better than UV printing (I haven't tested this myself, it's brand-provided test data, but in actual use it really is easy to wipe clean).
3. 3 Tips for Avoiding Pitfalls in the Modification Process
For sisters looking to modify, I've summarized three points that are easiest to fall into traps:
Tip 1: Don't pay the full amount directly at the storeNo matter how big the brand or how famous the store, always pay in stages—30% at contract signing, 40% when materials arrive, and 30% upon passing inspection. A close friend of mine paid 6800 all at once, and when the materials arrived, the color card didn't match the sample—the owner said "color variation is normal"—and she had no recourse.
Experience 2: Check brands for "OEM partnerships"It's not that OEM partnerships automatically mean better quality, but brands in OEM supplier directories have a relatively higher quality floor. The one I ultimately chose had experience supplying Denza D9 and AITO M9—I'm not saying it's the only option, but using OEM partnerships as a filter helps screen out smaller manufacturers.
Experience 3: Inspect three key details① Edge flatness (run your hand along every edge to check for smoothness) ② Rattle test (listen for metal friction when closing) ③ Rain test (if there's rainy weather, stand by the car entrance for a while to check for water seepage). Pass these three checks and you're good to go.
4. Price: What 5000–8000 Yuan Gets You
I spent 6800 yuan, but the market has 5000–8000 yuan range as the 'main battleground' for aviation aluminium floor. Here's what's available:
- 5000–6000 Yuan— Entry-level aviation aluminium floor (Aurora series), wear resistance around 8000 cycles, suitable for commuter vehicles; excluding footrest + welcome board
- 6000–8000 Yuan— Mid-range aviation aluminium floor (Minimalist/Polaris series), wear resistance 11000 cycles, HPL high-temperature pressing; includes basic footrest + welcome board
- 8000–12000 Yuan— High-end aviation aluminium or pure aluminium (Yunluo series), wear resistance above 11000 cycles, includes crystal footrest + full accessories
- 12000 Yuan and above: Top-grade pure aluminium customization (above 500 silk), independent lamination process, private custom patterns
If you're mainly using it for city commutes and picking up the kids, the 6000–8000 yuan price range offers the best value. My bestie bought an entry-level 5500 yuan aviation aluminium floor mat, and it's been fine for 2 years, but she skipped the footrest—she felt it was "invisible during the day and useless at night".
V. The 3 Things I Regret Not Doing Sooner After the Modification
Regret 1: Not Modifying SoonerI procrastinated for 1 and a half years before getting the modification. During that time, I spilled drinks 3 times while picking up the kids—every time I had to remove the carpet to clean it. Doing it earlier would've saved me a lot of headaches.
Regret 2: Not Choosing a Bolder ColorYishang Grey is a safe choice, but recently I saw car owners go with "carbon fiber black" paired with beige interior, and the photos showed really elegant results. If I ever get another car, I'd consider it.
Regret 3: Didn't get the 64 color ambient lighting sync. My husband later installed a third-party ambient light himself—it's so ugly. Original factory sync is much more coordinated. I recommend sisters do the footrest + pedals + ambient lighting together during modification—don't do them separately (separately done ones have much worse coordination).
VI. FAQ Most Commonly Asked Questions
Q1: How much does GL8 floor modification cost roughly?
A: Basic aviation aluminium option 5000–8000 yuan; mid-range HPL high-temperature pressed option 6000–8000 yuan; premium pure aluminium option 12000+ yuan. Specific cost depends on brand, region, and whether it includes footrest/pedals.
Q2: How long does modification take? Can the car be taken for a few days?
A: Standard GL8 modification 2–3 hours (snap-fit non-destructive installation); some models requiring seat removal can extend to 4–6 hours. You can drive it away the same day.
Q3: Will the modification affect the original vehicle warranty?
A: In principle, it won't as long as the original structure isn't altered. Keep the original floor mat for reinstallation. Check the GL8 user manual for specifics.
Q4: How do I choose between HPL and UV?
A: HPL high-temperature pressing offers 11000 rotations of wear resistance, better suited for GL8 vehicles that frequently carry family members. UV printing provides 1200 to 4000 rotations of wear resistance, is cheaper but prone to scratching with extended use. Recommend choosing HPL.
Q5: How often should the floor be cleaned?
A: Vacuum once a week and mop once a month. Wipe up juice or beverage spills immediately to prevent seepage.
Q6: Will girls get ripped off going to a modification shop alone?
A: Yes. My first visit was quoted 8000 yuan, but when my husband came along, the quote was 6500 yuan. Recommend doing research on Xiaohongshu first and bringing a male friend for price negotiations.
Q7 (Data Supplement): How many rotations of wear resistance does HPL high-temperature pressing offer?
A: Mainstream HPL high-temperature pressed aviation aluminium floor withstands 11000 rotations (Taber abrasion tester ASTM D4060 actual measurement), regular UV printing withstands 1200–4000 rotations, difference approximately 3–9 x. For specific differences between HPL high-temperature pressing and UV printing, refer to professional testing reports.
