This is for my Mini Cooper to start with; I currently have Promini (H&R Springs) on stock struts (I know bad juju, but it's only a temp mod). Here are my Ideas for a suspention setup: A: Keep the springs I got now http://www.promini.com/product-exec/product_id/193/category_id/86/search_year/2003/search_model/100 and put some Bilstien struts on. B: Get The H&R sport coilovers C: Get the H&R RSS Coilovers D: Get the Bilstien PSS9 coilovers As of now Im sure the PSS9's are the best of the setup I have chosen but Im not sure if they are worth the price. I drive the holy poo out of my car and plan on tracking it here shortly. I also currently have a rear sway bar, adjustable endlinks, Ft Strut bar, and a under body support system. I just would like to know what ya'll think would be the best set up for my driving habits and what set up would have the best "track" record.
