Hands down the best feeling heaviest shift knob. Combined with the acuity shifter, it makes shifting effortless, feels and looks great. One of the best mods you can get!

It’s a beautiful shift knob that feels great in my hand. Only caveat is the lightness of shift knob. Well made and gorgeous.

They did what they supposed to do delete my chrome

This adjustable shifter is great. No play in neutral and it makes rowing through the gears of my Si even more enjoyable than before. Shifting feels more solid. Pair this with the linkage bushings for an unbeatable experience. Install isn’t too bad. Just take your time and follow Acuity’s guide.
Impeccable service from Humza and his team as always.

I had been running a PRL mount for the past year and I found it to be getting a little soft. After chatting with Humza, I decided to upgrade to the Wunderladen street mount and it made way more of a difference than I expected. The car feels more settled during gear shifts and power is sent to the ground more effectively. Probably the best mount there is out right now.

bought this rotor to replace my old rotor, but the difference is very noticable, and to go along with the EBC green stuff pads, if you want, you’ll stop in these

Easy install and easy removal. Pretty good fitment considering the bolster difference between the 11th Gen Si and the Type R.
Overall I’d like to get an additional cover for the passenger side.

Works great and makes driving a lot more fun now that I'm able to practice heel to down shifting. I like the adjustability of it, I had it at position B and it was too close to my foot, changed it to C and it was better for my body geometry. Great cheap and safe upgrade!

Sounds great

Easy installation. Bought due to tinted tail lights, to help with reverse movements. They turned out perfectly, extra bright for the best vision.

Good quality, feels nice.

They fit a little loose at first like the last one I bought but once you sit on them for a week the tighten to the contours of the seat and look good. Very comfortable and easier to slide in and out of the seat with these on

I love it, by far my favorite !
It's so beautiful in my red and black SI !

It's so much better now, I can switch easyly between my 3 shift knobs. I highly recommand!

After the easy install(even for an old guy) the difference is noticeable and everything I was hoping for. None of the settings are abusive IMHO. Have only tossed it around a few corners on the street but the car stays flatter/feels more responsive in +R than before. Unity was excellent to work with and I'll probably order more stuff in the future. I LOVE IT!
