I ve considered lower my 645 vert for some time. Like you, I was curious which aftermarket springs are the best option. Hopefully, these past threads I pulled out of the search will provide you some insight along with member feedback. Welcome to the board and Good luck!
I am in the process right now, so once the car is lowered I'll provide feedback.
