for those with Selective Ride Control
I think I paid $100 to have the F45 disabled, then put on Bilstein HD shocks. It's definitely a stiff ride, but it handles way better.
I screwed up when I ordered them. I intended to order the standard Bilsteins, but hit the HD button instead. After I got 'em, I just said "oh what the hell".
If yours is a daily driver and if the your roads are not the best, you may not want the HD's.
Sidenote: there was a Corvette dealer in Montana offering a GM factory Mag Ride suspension replacement for the F45. But it was a couple grand, plus installation, and mine would have been serial no. 1.
Good luck.
