Hi All, Ive had Bilstein B6s and H&R springs on my car for a while and the aesthetic has been great, but long term performance has suffered from the longer rods on the struts and the time has come to reevaluate the suspension setup. I have a set of Ireland Engineering Springs and Ive heard good things. My question is: What spring set should I use with the Bilstein B8s I got, and what rear spring perch setting is the best for each option. Opinions, thoughts, advice, and criticism are all welcome. Thanks!

There is really no advice about the rear perch setting other than to use whichever one gives the body zero rake or a slight forward rake.

I've considered B6's, currently have H and R springs on Sachs/Boge shocks, may I ask what you have noticed in terms of degradation of the B6s? I like the slightly lowered look, but generally don't do a lot of performance driving and dont want an uncomfortable ride, which is my worry with B8s. Was it a decent set up, and then the shocks wore out, or was it always unsatisfactory? Any further details are appreciated.

Happy to contextualize. I did really like them when i put them on the car and they performed well; until they didn’t. The rears blew at least once per side. The fronts held up better, but they too suffered as they aged. The main issue with the rears was the rod length. B8s have a shorter rod so they handle the bumps with less action and less wear and tear. I could conceive of a burning with B6s in the front, but certainly not in my city environment. I’m also running 15s to account for this and still had a lot of trouble. Crossing my fingers that the B8s wear better. I have decided to stick with those and my H&Rs for now.

Just re-use your hnrs, IE is whack, I would never touch anything from them. I've heard way too many complaints about their products
