Yes. The springs have nothing to do with the active dampers. Eibach made springs specifically for the Si, tested with factory dampers.
0.9" front and 1.1" rear
My Mazda3 GT which was $1000 less, had a 9 speaker Bose with AudioPilot2. Beats the sh*t out of the Civic's NoName brand system.
I did add a 1500w mono amp, 12" Hertz in a sealed box, turned gain down, dialed up the frequency to fill in what's missing. Sounds better now, but begs to have all...
My VIN was out of range from the B-1-17 bulletin, but they did the necessary repairs (new damper mounts, bolts, etc) and noise went away... for two days... then we had a cold snap and it returned slowly. I was so happy the noise was gone until we were -21 again. I'm going to see if it's gone...
Sorry meant to update !
Yes its 90% gone. I wasn't expecting it to be fully quiet, as I'm sure you'll hear suspension no matter what. I'm quite happy with it. Make sure they follow the bulletin, and replace ALL the parts listsed, not just the damper mounts.
Tomorrow my Si gets the revised rear suspension parts. I've been complaining since week one on the hollow clunking I've been getting in our cold Canadian winters. Took the service manager for a ride (old buddy of mine), and he was annoyed with it too haha. I will post an update tomorrow !
Next...
If you have a laptop, or tablet, or spare phone, why not use the v1.2 features that does the same thing for a lot less? they updated a lot in 1.2 from v1
