X2. There are a few different brands out there and I'm pretty sure they about equal. I'm running PSC myself and I can zip into a parking spot with one finger on 37's. Made a huge difference.
So I couldn't resist. I ended up selling my 37 wildpeaks and grabbed a set of 37 Kevlar MTRs... And god what a difference. I have them on my yj in 35 and absolutely love them and I love them even more in 37!
