Ok I see what your saying. Now this won’t help the lean but will definitely help grip, have you done a performance alignment? I see the angles of your tires are all out of sorts in that picture. To me it looks like you need more negative camber. It will help keep the tires flat with maximum contact patch to the road when turning like in the picture. Your grip will raise exponentially with an alignment and it costs the least and doesn’t require replacing parts. Try getting as close to @Spoolin32
alignment specs as you can with stock suspension. Then change out parts if you want to. BTW do not cut out the bar on the Abarth! It is worth money and highly sought after by Miata community. Pay someone to pull it if the task is too daunting to do yourself. From what I have seen you have to pull the front bumper and belly pan and move or remove the intercooler hoses to get it out. First things first do an alignment and come back to let us know how it goes.
