I had the same issue a year or so ago with a leaking front and couldn't justify the cost of a new set of OEM EDC ... I figured if one was leaking, the others were sure to follow shortly.
I decided to go with KW V3's. Fitment was excellent and if you get the kit that replaces EDC, it comes with the delete's that plug-in to cancel any errors/codes automatically (suppresses codes).
I didn't have any issues with installing myself and hands-down one of the best improvements I've made to my car (I'm full spec built motor and bolt-ons). Handling is night-and-day compared to stock ... but depending on what settings you choose, you will feel like you're driving a sports car (vs OEM). It turns on a rail now and body roll is all but virtually eliminated. But because they are fully adjustable, you can customize both height and stiffness to your liking. I do miss the ability to use the rocker switch to pick firmness with Sport or Sport+ - Those settings still work for shift points, RPM, etc. just not the EDC (it stays locked to whatever manual settings you choose on the shock).
I daily drive my car and used the KW recommended settings: front compression damper 5 clicks from hardest, rebound 9 clicks and rear compression 6 clicks, rebound 9 clicks.
I highly recommend getting a good brand .... I was deciding between KW's and Ohlins and decided on KW's because it seemed the process to rebuild was a little easier (KW will rebuild if needed).
