Suspension Help- Bilstein Sports + ZHP Springs

[dlucas589]

Currently I have 1.5 yr old Bilstein sports with H&R Sport springs.

Living in WI and using the car primarily as my DD, I'd like to get back to stock riding height (snow and potholes are rough). My options as I see them now

1. Keep Bilstein Sports, buy used ZHP springs, sell H&R springs
2. Sell whole setup, buy new OE Sachs struts/shocks ($~470), buy used ZHP springs
3. Other options??

Thoughts?

Thanks--

i wonder if the bilstein sports can be used with the ZHP springs, because they are shorter than stock springs - but are they short enough to use with the bilstein sports? (which are shorter in stroke.)

Yep you can use zhp springs on the bilstein sport.

also- any downside to buying used springs? I've read that they don't really ever wear out...but at what point is it not a good idea to buy used? 100K? 200K?

You say you are using H&R sport springs. What model #? I just put 29484's on my wife's ZHP and it only lowered the front 3/4". The rear was not lowered at all. Just my thought, but you would probably be better to try a different shock. The Bilstein Sports are fairly harsh compared to others. Even the PSS (non-adjustables) that are on my 323ci are a "softer" ride than the Billy sports. I am lowered probably a good 3/4" all around further down than the 29484's.

Billy sports are harsh

Perhaps you want Billy Hd or bilstein touring class?

Billy Sports & HDs are valved identically.. the only difference is the shaft is shorter on the Sports, to accommodate lowering springs.

Shortly after I bought my car 2 years ago, I wound up refreshing the suspension using OE Sachs dampers. Wouldn't go that route again, they're too soft for my taste. I'd go Billy HD or Sport (whichever is correct for our stock springs) and call it a day. They'll last much longer than the Sachs dampers too.

Shipped my OEM springs out to you today. Hope they work out well for you!

Thanks again Marcus! I decided to buy the Koni FSD kit to put on the OEM springs. After researching, it seems the Koni are best suited for the awful Wisconsin pothole ridded roads while retaining some sport feel. Should work well in a DD setup with a lot of city driving.

Once swapped I will post the full set of Billy Sports and H&R springs for sale if anyone may be interested. Only ~10K miles!
