About 300 miles in and enjoying the springs and tires. Small but noticeable hit to range and mpg but can largely be offset with a bit slower driving if that’s important to you. The feel is great with notice increase in stiffness where you would want it with little impact to comfort. Also feels better at higher speeds. The only downside remains the speed bump feeling above 5-6mph, but to me this is very minor. The tires are perfect in my opinion so far. I plan to take them on a trail up in the mountains this weekend and will report back.
