Nobody?

It seems that the TRD rally dampers have significantly lower damping force at high damper speeds than the OEM dampers, despite spring rates being double in front and 60% higher in the rear.

Numbers (OEM converted and interpolated from BRZ damper shock dyno results by racecomp):

Damping force at (high) 0,3m/s damper speed

OEM vs TRD Rally

Front
Compression ~560 540
Rebound ~1690 1250

Rear
Compression ~735 400
Rebound ~1620 1120

Spring rates (kg/mm)
OEM GT86(EU) vs TRD Rally

Front
2,3 4,6

Rear
3,3 5,2

So it will definitely want to sit higher in it's springs and extend quicker, possibly a bit underdamped/more comfy?

Intrigued... might wanna try them if I can get a hold of them...
