Paddle shift conversion- Any new options?

Mates -

Have there been any advancements in paddle shift conversions applicable to the FTR gearbox on our pro formula Mazdas? I bought my car two years ago, and I think nearly everything has been gone through around this car and replaced. The only thing I’ve stalled on is adding paddle shift. Aside from wanting to learn in master manual, sequential shifting, I have bristled at the expected price of adding yet another $15,000 to a machine that will win no prize money.

Has anything changed or improved over the last two years?

Thank you in advance
