Upgrade options from front Bilstein 5100 shocks

I currently have 5100's on the middle setting with stock springs. Have had them for about 50k miles, mostly pavement with one trek through Death Valley and some trips to the off road park. I drive 90% on pavement. I wish they had more rebound damping, I'm sure on the low setting they are perfect, but then I'd lose my ~ 1" of lift. And I'd really like 1.5" of lift, but then it will just ride worse.

I'm contemplating the OME lift coilover package (90003 shocks with OME medium springs) from nisstec $626 plus shipping preassembled as a replacement/ugrade from the bilsteins. They have good reviews for ride and yield the amount of lift I'm looking for. Although, this puts me close to the price range of the Nisstec MK84 $725 and Nisstec adjustable coilover $750. And from here you can go Radflos, but then I'd looking to get new UCA's and that's out of my budget and overkill for my uses.

What are your thoughts on upgrade options for 1.5" lift in the front?

Truck: 2005 KC Nismo, rear suspension is Bilstein 5100's w/ PRG shackles on lowest setting.

Thanks
