FWIW my build specification lock date was last Friday with manufacture scheduled for completion 24 June. A week ago I was told that PCCBs were not available for my build slot and if I wanted them then I'd have to delay for an unspecified time. I went with steels to keep my slot. A bit miffed but not really stressed about it. Went with black calipers and may get ST discs at a later date when the first set of steels are dusted.

That actually is not the spring rate causing that, it is the lack of rebound damping. The stock PASM damping curves suck. The compression is too high and rebound is underdamped.
I went with 80/100 springs when adding my MCS 2-way dampers, once you dial up the rebound damping, even with the higher spring rates, it is very well controlled.

Honestly, they are a bit of a nice to have but in the real world it doesn't matter one iota - and if you track it a fair bit you're better of with steelies (lots more choice of rotors and pads). You did the right thing, far better to have a lock than an indeterminate wait ![Smilie](https://rennlist.com/forums/images/smilies/smile.gif)

I'm going to wait to get an allocation until I can get PCCBs and WP with mag wheels.
