I do not have first hand experience with it
But I can tell you the Mountune is the least harsh in terms of in cabin vibes and the next in line (at least that I offer) if the AWR 70a which happens to be the most affordable as well
Both are in stock, ready to rock (without vibes of course)
let me know if I can help

+1 To This, Ron's a great vendor with fast shipping, and even though I ordered a much stiffer variant of the AWR RMM which I didn't like at first, he sent out the 70a Bushing for me to swap out.
Long story short, I couldn't be happier with the overall feeling of the car now. The AWR RMM like most others is fairly easy to install (Less than an hour from the car being jacked up to lowered back on the ground), and the lowest(
?) price point on the market without sacrificing ANY quality.
... But nobody can beat Ron's prices, let's be honest.
