RoadsterSport B2 weighted aluminum shift knob

Brian's Big Knob! Designed on Brian's feedback, this CNC aluminum shift knob is internally weighted to give nice positive gear changes. Total weight is 385 grams. Anodized Red. Extra large 2" diameter gives you something big to hold on to when rowing through the gears.
This shift knob weighs 385 grams.
Brian's Comments. From the early days of Miata through the present the factory knob has struck me as comically small. Over the years we have offered many replacements that are a little bigger than stock, but I have always wanted one that really fills the hand. When our Fiat 124 joined the fleet I liked the weight of the knob it included, though the 124 is based on the ND Miata and uses an NC transmission the knob is heavier than any stock Miata knob ever was. So we sought to replicate (and slightly exceed) that weight while offering a bigger choice that fills the palm even more, result glides through shift gates easily! Currently using this in two of our NC projects and our Fiat 124.Black color version is same size, pictures below using black version to show scale compared to alternatives like 'Voodoo Knob Magnum' which is bigger than stock knob.
This shift knob is a nice subtle way to switch up the interior of your Miata. I have a soul red and the knob is a pretty good match to the red exterior and looks nice against the red stitching. For actual functionality against the stock shift knob I don't have a direct comparison as I also did the CravenSpeed Short Throw Shifter at the same time, but with this shift knob the shifts are nice and firm and I think helps resolve some of the noise complaints that I read from the CravenSpeed shifter. The feel is pretty good in your hand, it feels slightly larger than I might prefer if I could build my own, but overall it works.
I'm completely blown away with how this shifter knob improves the driving/shifting feel of my MSM! Descriptions don't do it justice. You have to feel it to believe it! Must have something to do with counterweighting the shift lever in it's throw radius. My MSM has the short shifter kit installed and this knob transforms it from good to fantastic! For the first time, I'm actually enjoying Mazda's 6 speed transmission! Throw away that factory knob and snag one of Brian's. You will not regret it! BTW, at the same time, I upgraded to the Cipher steering wheel. I'm having a great time in my "new" MSM!
Wow!!! Is an understatement . Wow!!! Goodwin racing . Awesome job with this big Shift knob! I've tried other shift knobs but this totally transformed my driving experience!
The weight is perfect and makes shifting so much smoother .( Also installed newbronze shifter bushing) . This is now my best bang for the buck upgrade! No kidding!
Thank you again Goodwin racing for innovative parts! and FUN!
