What is the best Ford Fiesta transmission for optimal performance?

I have a Ford Fiesta ST and I want to upgrade my transmission for better performance. Which transmission should I choose and what things should I consider before making a decision?

I highly recommend upgrading to the Ford Performance Short Throw Shifter for your Fiesta ST. It offers shorter, crisper shifts and enhances overall driving experience.

Another option would be the Quaife ATB Limited Slip Differential, which will improve your Fiesta's traction and handling.

If you're looking for a cost-effective option, I suggest getting a professional tune for your current transmission, which can significantly improve its performance.
