Installed on my 2009 Lexus IS-F with Fortune Auto Series 500 coils. The system gives me about 2" of front end lift whenever I need it. I've had it for about 1-1/2 yrs, with no problems at all. Very high quality components. I'm no longer smashing up my front lip and belly pan. If you don't want to go with bags, this is the way to go!
