In my experience, polyurethanes like Rally Armor UR Series Mud Flaps are the gold standard for flexibility, but since they were already mentioned, I'd suggest looking into Rek Gen Rally Edition Mud Flaps. They use a mid-density plastic that's stiffer than Rally Armor but less brittle than RokBlokz. They're around $100, mount to factory holes, and won't flap as much at highway speeds. Honestly, wind noise is negligible on the BRZ since the cabin isn't exactly library-quiet anyway!

In my experience, picking the right mud flaps for a low car like the BRZ is a bit of a gamble, and honestly, I've had some mixed results. I totally get the paranoia about the paint—the rocker panels on these cars are basically rock magnets.

I've tried both of the main contenders you mentioned, and here's how they stack up from a more cautious perspective:

* Rally Armor UR Series Mud Flaps for 2022+ Subaru BRZ: These are definitely the "safe" choice for the long haul. Because they're made of polyurethane, they stay flexible even in freezing temps. However, I found them a bit too floppy for my liking at highway speeds, and unfortunately, they can look slightly messy when they're flapping around.
* RokBlokz Mud Flaps for 2022+ Subaru BRZ/GR86: I switched to these because I wanted that rigid, clean look. That said, I had issues with scraping almost immediately after a mild drop. Since they don't bend like the Rally Armors, every time you hit a speed bump or a dip, you'll hear that cringey plastic-on-asphalt sound. It actually cracked one of my mounting points over time.

Personally, if you're planning on lowering the car, I'd suggest going with the Rally Armor UR Series Mud Flaps. Even though they aren't as "sturdy" looking, the hardware is top-notch and they won't put stress on your fender liners if you scrape. Just a heads up, the installation is mostly bolt-on, but take your time with the rear brackets so they sit straight. Good luck with the build!

For your situation, I'd be careful with the more rigid options if you're planning to lower the car. In my experience, the RokBlokz Mud Flaps for 2022+ Subaru BRZ are great for that 'sturdy' look you want, but honestly, they can catch on speed bumps once you drop the ride height. Since you're on a budget, you might want to consider the MegaChip Subaru BRZ/Toyota GR86 Rock Guards. They're super low-profile and way cheaper than the full rally sets, plus they use factory holes so no drilling! Just a thought if you want protection without the 'floppy' look.

Hmm, I've had a different experience when it comes to prioritizing aesthetics over pure safety and long-term reliability. Not to disagree with the previous suggestions, but I'd actually suggest a different approach for someone who is planning to lower their car soon.

Warning: If you go with a rigid flap and lower your suspension, you're looking at a high risk of cracking your fender liners or even damaging the mounting tabs on the bumper if you catch a speed bump or a driveway incline! It’s seriously not worth the risk to your brand-new paint and bodywork just for a 'stiff' look.

Since you're looking for that perfect middle ground, I'd suggest looking at ZL1 Addons Deluxe Rock Guards for 2022-2023 Subaru BRZ. They are much more subtle than the full rally-style flaps, so they don't look 'floppy' like some people fear with the bigger brands, but they offer incredible protection for those rocker panels. Another amazing choice that's often overlooked is the Megachip Chip Guards for 2022+ BRZ/GR86. These are fantastic because they're super low-profile and don't create that parachute effect at highway speeds, which honestly helps keep wind noise at an absolute minimum compared to the wider rally flaps!

tbh, I think the Megachip Chip Guards are the safest bet for a lowered car because they provide a really clean, OEM+ look while still stopping those pebbles from sandblasting your rear bumper. I've been through a few winters now and these mid-density materials hold up way better against road salt and grime without fading! Good luck with the new ride, it's a fantastic car!

Just saw this thread and felt like I should weigh in. Unfortunately, I've had some pretty bad luck with most of the popular kits on the market lately. I've tried multiple setups on my own builds and the hardware quality just isn't what it used to be, especially when you're dealing with road salt and constant grit. It's frustrating when you spend money on a premium kit and the brackets start to rust within six months. From my DIY experience, there are a few things that always seem to go wrong:

• The mounting hardware often strips if you're not incredibly careful with the torque.
• Most flaps don't sit perfectly flush, which lets sand get trapped between the plastic and your paint.
• Rigid designs almost always cause issues the moment you hit a driveway incline once you're lowered. Honestly, if you want to avoid the headache, just get whatever Sparco Mud Flaps or Verus Engineering Rock Guards you can find that fit your year. They aren't perfect, but they've given me fewer issues than the big rally brands everyone else suggests. It's just a shame that we have to spend this much time worrying about paint that should've been better from the factory.

Congrats on the new ride!!! Honestly, the paint on these cars is pretty thin, so getting protection on there is basically mandatory if you're hitting those backroads. I've done my fair share of installs on the twins, and the 'no-drill' claim can sometimes be a bit of a stretch depending on your patience level lol. Before I jump in with a recommendation, are you planning to DIY this in your driveway, or are you looking for something to take to a professional? Also, how comfortable are you with potentially pulling the rear wheels off for access? Knowing your tool situation—like if you have a right-angle bit driver or a jack—definitely changes which mounting hardware is actually 'easy' to work with. It's usually a pretty straightforward job, but some kits are definitely more finicky than others when you're working in that tight wheel well space!
