A few FA500 notes: While the valving for 500 series “ high flow digressive” piston is far more linear than the 510 series “Concave Flow Digressive” piston, the 500 series is more similar to a linear damper than a digressive damper. 500 series have an open bleed circuit for damping adjustment, so while the 24 step primarily adjust rebound, it does adjust compression as well. Great comparison, thank you for going over all the features objectively as it’s often very difficult to differentiate between products in this segment!

If you are not racing for money/job just get the BC. Their DS series shock body are only 150$ each. Remember a rebuild is about 150$/corner and you pay shipping there and back. BC, just replace every 5yrs or so to maintain performance. It's a no brainer IMO.

Great comparison. If you want a bit more comfort without sacrificing too much performance with the Fortune Autos you can option lower rate springs in the rear. I did 8k in the front and 6k in the rear on my WRX.

Dont let Cygnus see this, he will be dogging BCs and silvers etc...
