You want to get the best road balance for everyday use?

Then 5100 STREET TCO SUSPENSION is a perfect option for you.

Maximize grip by controlling rebound and rideheight of your car. These coilovers include springs and are designed to run OEM top mounts. In this set front and rear dampers utilize a coilover design. By choosing this design you prioritize adjustability and the performance of your car. Coilovers which will offer more adjustability for both damping settings and ride height, and typically provide more consistent and predictable handling characteristics.

The initial setup for setting and spring rates is rooted in our extensive development and testing process. Individual preferences can easily be fine-tuned by making adjustments to the rebound knob or altering the ride height. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements.

With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. AST Suspension is a monotube design. This is a benefit for you because these dampers offer a large piston to control the adjustability of rebound damping. There is no aeration or foaming in monotube dampers, this will result in a more responsive valving. AST high pressure dampers offers additional resistance, based on the driving conditions. It will increase performance when you need it.

These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.

Well made
Size: 11, Color: Black/Geyser
The first thing that stands out about the Columbia PFG Castback Flip sandals is the solid build and clean fishing-inspired design. The Black/Geyser color combination looks sharp and matches the product photos well. The straps feel durable and comfortable against the foot, and the footbed has a slightly cushioned feel that makes them comfortable right out of the box. Overall construction feels sturdy, which is what you’d expect from something designed for outdoor or water use. In everyday wear, the sandals are comfortable and easy to walk in. The footbed provides decent grip and support, and the textured surface helps keep your foot from sliding around when they get wet. They work well for casual use, whether it’s around the house, at the beach, or after a day on the water. The lightweight feel also makes them easy to pack for trips or outdoor activities. After wearing them for a while, they hold up well and remain comfortable for daily use. The materials seem durable and the straps stay secure without stretching out. They’re simple, reliable sandals that work well for warm weather, boating, or casual summer wear. Overall, they’re a solid choice for anyone looking for comfortable flip flops with a slightly more rugged outdoor style.

Extremely comfortable with slight roomy fit
Size: 11, Color: Black/Geyser, Size: 11, Color: Black/Geyser
These are easily the most comfortable flip flops I have ever owned. From the moment I put them on, there was no break in period at all. They felt soft, supportive, and ready for all day wear right out of the box. The cushioning is excellent without feeling too soft, and they have a nice stable feel when walking. They are lightweight and clearly made with quality materials, making them great for everyday use or around water. One thing to note is that they run a little on the larger side, so if you are between sizes, you may want to consider sizing down for a better fit. Overall, these are a great combination of comfort, durability, and function. I would absolutely recommend them, especially if comfort is your top priority. (Excuse the teeth marks- my dog unfortunately got ahold of them before I snapped the photo- they are PERFECT out of the box)

Comfortable Flip-Flops with a Clean, Sporty Look
Size: 13, Color: Black/Geyser
I picked up the Columbia Men’s PFG Castback Flip in the black and white colorway, and the first thing I noticed was how comfortable they felt right out of the box. How They’ve Been Used: Even though it’s still winter, I’ve been wearing them around the house occasionally to get a feel for the fit and comfort. I plan to use them more regularly outdoors once the weather warms up. What Worked Well: Immediate Comfort: The footbed feels cushioned and supportive without needing a break-in period. Secure Fit: The straps sit comfortably without rubbing or feeling stiff. Lightweight Design: Easy to slip on and off for quick wear. Clean Style: The black and white combination gives them a sharp, versatile look. Positive Feedback: My wife has already commented on how good they look. Things to Keep in Mind: Seasonal Use: Best suited for warmer weather and casual settings. Sizing: Checking the size guide helps ensure the right fit. Bottom Line: Based on my experience so far, these flip-flops offer a great balance of comfort and style. They’re comfortable enough for everyday wear and look sharp enough for casual outings. I’m looking forward to putting them to full use once spring arrives.

Columbia always makes great stuff
Size: 14, Color: Espresso II/Black
Even with my flat feet these offer a lot of padding which makes these extremely comfortable. They increase my height about an inch haha. These are great for walking around the beach or just going for walks. The tread on the bottom of these make walking up hills where the surfaces are not completely even extremely easy and very grippy. Time will tell how durable these are, but so far they're holding up very well.

Comfortable Lightweight Flip Flops with Reliable Grip
Size: 9, Color: Black/Geyser, Size: 9, Color: Black/Geyser
These flip flops have an excellent fit with a cushioned footbed that makes them very comfortable to wear for long periods. The grip is strong on wet surfaces, which adds confidence when walking around pools, beaches, or after rain. The overall quality feels top tier, and the color looks clean and well finished. They are lightweight, and the sizing was spot on, making them easy to slip on and wear throughout the day.
