Look's like BC has a beef with Tein and trying to cut in on the market.
If they are going to compare to tein, it should be:
Racing spec vrs Monoflex
N spec vrs tein flex
Edit: Some facts that I have picked up.
* Both BC & Tein offer dampers for NB and NA, only Tein offer dampers for the NC
* Spring rates for all 4 dampers in question are almost identical.
* Monoflex have micro speed valve technology, BC doesnt.
* BC are made in taiwan, Tein are not.
