Thank you for your detailed feedback - very much appreciatedmaupineda wrote: ↑Sun Mar 24, 2024 6:26 pm it very likely will due to the extra nitrogen gas fill. they will settle some after some miles and time. My car lost about 5-7mm in about a year and staid there.
I never used the Bilstein shocks with OE springs as I went the coil over route, so my numbers will be different some.
What I can tell you is that I chose a spring rate that was close to OE (225 lb/in). OE spring is (according to some forum data) 194 - 224 (progressive). However, I initially chose 250 in/lb spring and I was having trouble to meet OE height due to the Bilstein shocks (even though my math indicated otherwise). My rate was 10% higher, but the spring I chose was also shorter. I had to go down to 224 in/lb springs, and then the threaded body of the H&R strut allowed for the desired height.
If you want to compensate for any height gain with B6, you can add camber plates which have a lower height.
All this is a rabbit hole, I did it as I was already deep into it and wanted the car to be exactly what I wanted.
I guessed I will just start with the B6 struts/shocks with the OE springs. If it sits higher than expected, then I'll take your advice of going to camber plates. I don't track/autocross the car to warrant coilover at this point.
