bought the UUC RK6A
I ended up getting a knob made by UUC, the RK6A height adjustable shift knob, specifically.
I was all set to buy Dwight's ZHP M-less knob (here's a shout-out to Dwight for being a cool guy!), but happened to be at the local dealership yesterday morning and was inquiring about a couple things at the parts counter. Someone in the back heard me asking about knobs and came out to see if I was interested in aftermarket products. As it turns out, they had a few of these UUC knobs they were trying to get rid of. When he took it out of the box, I knew it was exactly what I'd been looking for: round, metal, but not polished, weighted, simple black 6-speed pattern insert. Sold. Serendipity.
In another serendipitous moment, while my car waited for me in the exit lane. The tech came out to remove my standard knob. He turned out to be an instructor in the local BMWCCA chapter, so we chatted shop for a few minutes.
I knew the knob would shorten my throw. I knew the knob was weighted to offset the smaller amount of leverage. What I did not expect was how much smoother shifting would feel. It's faster of course, but why is it smoother? The weight? Wonderful benefit! Highly recommended. That's the long and short of it. :thumbup:
