Yup, seems to have gone up in price since I bought them ($76 a piece). FCP has them for a little cheaper:Quote:

Many members here have gone with the Z4M solid rubber FCABs.
EDIT: Cheaper if you buy just the bushings and install them into your existing lollypops.

The BMW Mini Parts Store has them for $69.26 per side. Worth it though.
I have the Z4M FCABs and quite like them. They increase caster a bit and changes steering feel a bit, which I preferred. Then again, I'm sure I would have been satisfied with the stock FCABs but they are fluid filled rather than solid rubber.
I didn't notice squat changing to them except it "ruined" my stock car alignment figures and now I have to explain it, fortunately, RRT has a record of it for my car, but if I went anywhere else...Quote:

The range for caster is 1 degree (5.1 degree - 6.1 degree ).Quote:

So if your alignment falls into that range, it is not " ruined".
Our cars with the Z4M are usually at the top of that range (6.1 degrees). Cars with the stock FCAB are usually at 5.1 degrees from the factory.
Positive caster will make the vehicle more stable at high speeds, and will increase tire lean when cornering. Lastly it will increase steering effort.
The first two items are the most noticeable.
Hmm Thanks for the informative response Vas, to my "stay stock stay worry free" ignorant one. Mine are at 6.1 now and it is red on the sheet/out of spec. I'll check the folder when I get home.Quote:

Even if it is still red, still within Spec though. Don't fret about it.Quote:
