I know the guys who frequented the Roadster Performance Discussion knew a thing or two about DIY tweaking of cars in general and I'm hoping that people here have a similar knowledge base. I know next to nothing! I have a Model S-Performance (with the air suspension) and know that through the user interface you can push a button for suspension to be soft, standard or performance. "Problem" is that on performance, I'd consider the suspension "soft" which, I know, is the intent of Tesla because those who want a car that insulates them from the road far out number those who want to feel it. BUT there are different strokes for different folks so I'll get to my question... is there a Tesla-approved or non Tesla-considered (that would not invalidate the warranty) way to adjust the suspension to make it stiffer for the twisties?
