I would certainly be doing S3 rears, have them on mine and the car is so planted and level under heavy braking
Am sure Hurdy did mention publicly the concerns with the Forge actuator. Yes, it is a good product, but it needs to be set up correctly and this can only be done with a serious amount of data logging to make sure that it is set just right for that specific application. IMHO it is not worth the hassle.
