The bushings I removed looked worse than gsxr's. When anyone got into or out of the car there was a sound like a submarine going too deep. Now there's just a clang like an exhaust pipe hitting something.
It feels like the rear sits higher by an inch. Ride is notably smoother. Bumps and road irregularities I'm very familiar with felt rounder today
The only in-situ check I can imagine is to compress the spring, detatch the shock and see if the LCA wiggles relative to the hub carrier.
A pair of those angled struts and a set of diff bushings went in sometime ago. I also freed up park brakes that looked like they hadn't been used in years. Everything else I checked looks serviceable. I've yet to check the subframe bushings.
