The Random E46/ZHP Question Thread

unless you...

a) buy koni yellow 911 rears (top-adjustable), or;
b) buy top-adjustable koni yellow rears from ground control (which i suspect are actually 911 rears, LOL)

Do you have part numbers for the 911 rears? The Ground Control ones were quite expensive when I was looking for my suspension refresh a couple of years ago.

All very interesting and very helpful. I went with a full set of the FSD's: will install the fronts when they need to go in. FSD's seem not to be adjustable, amirite?

Yup, not adjustable...

yep, it's 82101159SPORT. roughly $208/each at ECS, but i bet RCA could get you them cheaper.

Thanks very much to everyone for their assistance above.

I think you're really going to like the FSD's. I haven't yet installed them on a ZHP, but have them on another car and they completely transformed both the ride comfort and cornering stability. This discussion confirmed for me that they'll deliver similar results in this car:

Nothing against the adjustables at all, though. I like FSD's for my driving because my commute is riddled with both railroads and twisties and the shocks are well tuned for both without me having to pull over and make adjustments between obstacles.

Trust me: I've had adjustables before and just set them a notch harder than the middle and went on my way. Even that was more attention than I wanted to pay to the matter. I'm going to enjoy the FSD's.

What are the part numbers for our front control arms? The standard part numbers seem to be 31122282121/31122282122 but those seem to be superseded by 31122341297/31122341828?

Then there's a BMW kit that has both, part no. 31120429578.

Seems like you are right. 31122282121/31122282122 (BMW branded ones) have been superseded by 31122341297/31122341298. I see ECS Tuning's website confirming that:

https://www.ecstuning.com/b-genuine-...t/31122341297/

However, the Lemforder branded parts still carry the old part numbers:

Maybe call FCP Euro or ECS Tuning and confirm. It is possible that they might not have updated the website.
