suspension is the weakest link for MPS6

Is this one B8?
Bilstein HD Series Shocks for Mazda 6 and Mazdaspeed 6 (complete set) - Revolution Performance Motorsports!

No, they're B6's but unusually they're still monotube, so would be comparable, if not a little better than the twin tube Tein.

I doubt the Tein will be a step backwards compare to this shocks...

Compared to B6's, maybe, maybe not, I'd still personally take the B6 without question.
Compared to B8's, no debate about it, the Tein would be a a MASSIVE step backwards in terms of performance...

RPM store part numbers are the B8's.

Nup, they're the B6.

B8's to suit are $252 per shock front or rear.

I stand corrected. yes these are B6s
PN for the B8s are BE5-A259, A260 & A261.

seems like this upgrade is not really worth much, I think I will keep the Bilstein shocks and enjoy as much zoom zoom as I can on the track. Thanks guys..
