Don't know mate I got Tein RS not monoflex, they are totally different.
Adjustability is good, but sometimes not soo great. My coils have alot of adjustment but I havn't been able to found a very good setup yet. On the street it's usless to adjust you just dont have enough road to feel the difference. It's alot of playing around especially with the remote resivor tanks.
Ahh ludacrs beat me too it with the kw and pss9 thread.
There are heaps of first hand feedback from the usa. One guy Stinkytofu has tested afew diffrent coils on his s2000, but all the ratings are more to do with track then street. As you all know any coil will do for the street.
It's not just the s2000 that will handle crap if its dropped on its ass, most cars are like that. But that doesn't mean lowsetup cars are always crap, with the right settings testing and research you could have a very powerful low setup. The J's racing ap1 had a very low setup yet handled very well and had no problems with the bumps on the touge, but of corse.. they are professionals :)
I've only heard good things about the Toda coils, but I havn't seen anyone with them on a s2000 and they real expensive too, maybe they're up there with the motons and jrz but they cost an arm and a leg lol.
