Information on 'Bilstein adjustable ride control system'?





I was checking out the option codes on the '98 'Vette that I bought recently...and found that it has the Z51 performance handling package, and the 'Bilstein adjustable ride control system'.
I've found info. on the Z51 package...but am not clear on exactly what the Bilstein system adds to this? I've heard of adjustable shocks...but there doesn't seem to be any apparent way of adjusting these?
Can anyone shed some further light on this?
Thanks!

1) base FE1 suspension
2) F-45 Real Time Damping (adjustible shock absorbers)
3) Z-51 Performance Handling Package
A combo of the Z51 and F45 are not available together.





This was obviously an error then - I do have the Z51 option, but not the F45 'selective real time damping'.
I spotted a few other obvious errors in this book, so although it was an interesting read, had to be taken with a grain of salt.
Thanks for clearing this up!
Robert
