(Copied from my post on another Evo forum)

Hello guys and gals!

Almost a year ago I purchased an Evo X....and was immediately dissatisfied with the shifting feel and consistency. I went through and changed all the bushings and it got better. Then added an AMS Delrin shift knob and although it is light weight, the height of the knob made shifting a little better. I recently added a TWM shifter cage replacement setup and it help very much with precision. But, it really brought to light the shift knobs weight problem. I could have very well just went and bought a heavy metal shift knob from literally ANY vender and it would have worked just fine. But one of the reasons I went with the AMS in the first place was because it was made of delrin. And delrin doesn't retain heat like a metal shift knob would (Had a VERY heavy Skunk2 knob on my DSM and it boiled the paint on the H-pattern!). So I devised a solution.

I gathered some measuring tools to get exact specs and laid out exactly how I was going to proceed with my project. Then found a competent machine shop that could get it exactly how I wanted it. And here is the result:


Looks pretty normal to me


But as you can see, I drilled it out and then pressed in (to EXACT tolerances) a slug of brass to add weight


Even left the step height that the knob originally had. And drilled and tapped it to the same spec that the knob originally had too.

The end result: IT'S FRIGGIN' AWESOME! I unfortunately don't have access myself to a gram scale so I can't tell you an exact weight difference (will try and get that done soon), but I will say it is noticeable for sure. And I'd imagine that doing this modification to any setup that currently uses the AMS knob will notice a massive difference.

Currently there is only one of these made, but if a friend of mine likes the weight, I will make a second one for his track DSM so I can have another opinion on how this has turned out.

Just wanted to share with you all!

Thank you
