In my experience, finding the right balance between protection and that sleek GS profile is a total nightmare because most universal flaps look like truck accessories. Honestly, I've tried many different setups over the years, and for the Regal GS, you definitely want to go with GM Genuine Parts 19170641 Front Splash Guards and the matching GM Genuine Parts 19170643 Rear Splash Guards.

I'm highkey obsessed with the OEM-plus look, and these are basically the only ones that contour perfectly to the GS-specific side skirts and rear fascia. Most aftermarket stuff like WeatherTech MudFlaps are great for trucks, but they're way too bulky for our cars. The GM ones are molded specifically for the body lines, so they don't look like an afterthought.

Now, about the "drill-free" part—the fronts usually utilize existing screws and some heavy-duty 3M tape that comes pre-applied. For the rears, you might have to pop one tiny hole in the plastic wheel well liner, but seriously, it's into plastic, not metal, so no rust worries! I've hit 85+ on the highway and they don't budge at all. If you want even more low-profile protection, I've seen some guys run ZL1 Addons Deluxe Rock Guards for Buick Regal, which are literally just flat sheets that disappear into the wheel well. But for road salt? The molded GM ones are way better cuz they catch the slush before it hits your doors. gl man!

> I’m looking to protect my Regal GS from road salt and gravel, but I’m worried about ruining that sporty profile.

In my experience, you gotta be really careful about how these things attach cuz some cheap sets rattle loose at 80mph and actually scratch your paint. I've tried many different setups over the years and honestly, for safety and a rock-solid fit, look into ZL1 Addons Deluxe Rock Guards for Buick Regal GS. They're super low-profile so they don't mess with the lines, but they're stiff enough to handle highway speeds without flapping around. Just make sure you double-check the clearance with those GS side skirts before you tighten everything down!! Good luck!

Honestly, just go with a set from WeatherTech or Husky. They basically use aerodynamic engineering to keep a slim profile while blocking debris. Plus, they're super easy on the wallet long-term!

Like someone mentioned, those side skirts change the whole geometry compared to the base Regal and make fitment a real chore. In my experience over the years, the biggest headache isnt even the look, it is how the material reacts to temperature changes. I have tried many different setups and once had a set that felt solid in the summer but turned super brittle once it dropped below freezing. I hit a chunk of road ice and the whole thing just snapped right off. Nowadays I only look for high-quality TPE because it stays flexible when the weather turns. My current setup uses that kind of semi-flexible composite and it doesnt vibrate or hum at 80mph like the stiffer ABS ones do. Plus, you gotta watch out for how much grit gets trapped behind them... if the material is too hard, it basically acts like sandpaper against your paint when the car vibrates. I learned the hard way that a bit of give in the material is way better for the clear coat in the long run.

So I went through this exact struggle last year with my own GS. I was super paranoid about those side skirts cuz they're basically magnets for rock chips, but I also didn't wanna spend a fortune or ruin the lines.

I looked at the pricey options, but honestly, I ended up going a cheaper route that worked out great. Just sharing my experience:

1. I grabbed a set of A-Premium Splash Guards for Buick Regal off Amazon for about $25-30.
2. I was worried they'd be flimsy, but they actually stayed rock solid even at 80mph on the tollway.
3. Ngl, I had to be careful with the fitment around the GS trim, but with some patience, they tucked in nice and tight.

Basically, I saved like $60 over the OEM stuff and they've survived a full salt season already. It works if you're on a budget! 👍
