OK, something made from a billet of 6061 aluminum might work. On the image, the paddles don't extend past the underside of the steering wheel spokes. See what i mean? I need them longer.
Let me break it down all the way: When i make a left turn at the light, my right hand is turning the wheel halfway to lock, while my left hand is trying to tap the up paddle directly obstructed by the other hand. i know i know, first reaction is , well why don't you just tap the upshifter with your right hand , genius? Because at that angle the pinky is the closest digit to the paddle and it doesn't bend backwards.
I'd also like one of paddles knurled in the back while the other smooth, to differentiate up and down shifter.
