Hello BMW Experts!
I had m3 RTABs + limiters, and they felt very good at first. Mine were totally shot at ~ 43k miles, though.
So I recently put in UUC red urethane RTABs, which have a 75A hardness rating, softer than the powerflex (85a & up) ones, etc. They also have big channels which should help hold extra grease, making the intervals between re-greaseing longer & lessening the noise potential (mine are silent).
Of course these things are hard to really compare, but I think they make the car more stable than the m3/limiter combo. They should last much longer without deteriorating (if greased properly initially) also. They might take some kinds of bumps a little harder, but generally they have no NHV drawbacks.
YMMV!
