They seemed to sustain a lot of abuse, but now I think after about two years of some hard driving, the driver's side front has a blown seal, which you can hear from inside the car when going over bumps.
I've found a number of places where you can buy a whole set for about $300. I think that these dampers are good for both AutoX and drifting applications (maybe even the occasional road race) where your car is also daily driven, and they match well with a semi-stiff spring setup (about 8kg/6kg).
I also had the opportunity to drive a mildy modified '86 Corolla coupe (hachi-roku for you fans out there) with the same dampers, and I have to say I was very impressed. The car was ultra stable on the track, and it broke traction consistantly and smoothly. If an FC isn't your only car, you may want to look into getting them for all your rides!
Feel free to add in your knowledge.
