Pulled the trigger on the Wunderlich seat! Build quality is superb! Looks great, feels great. A little firmer than stocker. I went with the standard and it is on par with BMW ‘s standard! I have to take it out on a lengthy ride for the true test. Just a heads up on the seat pan. The one I received had a different configuration for the tools under passenger seat! Maybe a slight design change. I am currently working with them on a possible swap. I don’t use the passenger seat often so not a deal breaker!
