^ yup, that's me! funny, small world!
Yeah, Tiens are surprisingly well built, but I think their performance leaves something to be desired.
the newer monoflex are better and their track suspensions are surprisingly decent.
Hopefully I don't run into the same thing. The H&Rs are the only decent quality $1000-$1300 coilovers out there for the E9x, hopefully they aren't a reliability problem. I put 75k miles on a set on my E36 M3! revalved them once but they were in perfect internal condition when I did... I just wanted to go with stiffer springs.
