I've only logged a few miles with these so far but here's what I've noticed:
- There is a very slight hum going down smooth pavement. It's not very noticeable or distracting, especially with the radio on low or in conversation. My wife hasn't noticed it yet so that tells me it's just me listening for it. But it is there.
- I feel a bit more grip, especially at lower speeds.
- Cornering takes slightly more effort at low speeds. This is kind of nice really because with the OEM tires it felt a bit more sloppy.
- Small bumps are less harsh.
- There's a slight decrease in the brake dive. It's not much but it feels different and even the wife noticed it. I still plan to at least add the 5100s and maybe springs, but I was surprised to see this.
All of these are minor observations but interesting nonetheless. Besides, it's my only mod so far so I have to enjoy the little things.
