Recently my paddle shifters have begun to feel cheap and are getting harder to press, I sometimes need to press it a few times to allow a gear change, I am looking to replace or fix them but have no idea how to go about it, do I need a new steering wheel? Can I buy replacement or different ones for the car and replace the old ones? Any help would be nice especially where to look for new ones, dont have to be OEM, thank you for any help.
