Most cost efficient way to go to an OEM sport suspension from non-sport on an xi?

Hi all,

Car is at 86k. Rides so much better than my previous car, but I feel like a suspension upgrade is this one's future. Would love to lower it with the B12 kit, but I have to consider that it's a daily driver and will see plenty of snowy winter days. So, I was wondering how to get something factory height, but still lower than the non-sport xi suspension and maybe not have to spend $900 + install costs.

Thanks, any suggestions would be greatly appreciated!

I've done the research for my E91 xdrive and unless you want to put together something completely custom (specific custom springs etc.) the only thing I came up with is ST X or KW V1 coilovers. Everything else goes lower.

Yea, seems the KW v1 offer enough travel that I could raise them up for winter driving higher than other options. Like the BC have a minimum 2 inch drop, the KW advertises .6" at it's tallest. Not so much cost effective, but it is what is lol

Well I put the regular 'i' sport springs on my. I think there was a small drop. Some of this will depend on which 'D numbers' you use. I used 'D5' front and 'D3' rear. Front is still a little higher than rear, but not too bad. These are widely available used -- which is how I got mine.

I originally put Bilstein B8's on 4 corners -- which helped on the 'crashing' but rode quite firmly. A few years later I swapped out the front's for Koni yellows which gave a more compliant ride. I'm pretty happy with the way it is now. I do recommend using Z4m bumpstops on the Konis (Bilsteins don't need bumpstops). Also I'd replace the shock mounts as well. I used the Dinan rear mounts.

Finally I'd recommend monitoring the tire pressure. When the oil change place overfills the tires -- I can feel it. 33/37 is as high as I'd go -- and this is with non-RFTs.
