I was thinking about making a rolling anti lag mount and button with a wireless transmitter myself. Wanted to see if anyone knew of a solution for this? Wanted to keep the button on the steering wheel somewhere. Striking out trying to find one outside of the universal ones you find from places like Motion Raceworks.

 

I bought some micro switches off amazon and put one under the little cubby by the radio, super easy to wire in and its right by the shifter for when you let off the button and completely hidden.
