UPDATE:

It's been a little over 3 years since I originally installed the TRD rally suspension. I stopped using the TRD Rally dampers after I totaled my FRS. I wasn't happy with the rear of the car, it felt like it bounced off of bumps instead of soaking them up with the TRD rally dampers. I picked up a 2019 Series Grey and was very impressed by the performance package SACHS which had much better valving. So I opted to pair the TRD Rally Springs with the SACHS and have been extremely happy with the car since.

I recently got to dyno test the rears, and they looked to have some major issues. I think they were bad from the factory and had massive rebound cavitation. This explains why they would bounce off of bumps, as the rebound was basically non-existant.

I may not be on these springs much longer, as plans are in the works on getting some propper tarmac coilovers. Updates on those a bit later.
