I went from stock to Bilstein HD on the rear of my 3.0i and it was much firmer. Then, I needed them on my 4.8is when backordered for MONTHS, so I moved them over and rode new Bilstein tourings on the 3.0i. If you like stock feel, tourings maintained that very well. If you want more of a “truck” feel…go HD. I’m not sure exactly what difference in feeling would be on fronts…but thought I would share. Good luck!
