Garbage... like other Chinese suspensions, brakes, etc...
D2, Ksport, and not sure what is the name of 3rd brand... all manufactured in same factory... If you compare pictures it is same, just different color.
BC, Megan,ect.
And as much as people say how bad they are, they really aren't that bad. Are they KW's, Ohlins, JRZ, or upper level Blisteins - no, of course not. But the internet makes it seem like your car is literally going to drive itself off a cliff because the shock imploded on itself. The thing I found bad about cheaper shocks was their "small bump" damping and rebound characteristics.
I've driven in cars with Ksports, Tein, BC's, ect and it's almost always been an improvement over stock in terms of PERFORMANCE, not comfort, ect. Also note that those cars were not S2K's, BRZ's, STI's, M3's, S4's, 911's, ect that have a good suspension in its stock form.
