I installed Bilstein 5100's all the way around with stock coils. I set the front shock to 2.5", and in the rear, I went with the 1.5" daystar spacer. I did a full write up on it if you are interested.
Bilstein 5100 2.5" Front and Daystar 1.5" Rear Spacer Write-up
I personally felt like this lift improved my ride quality significantly and only cost me around $450 out the door. The suspension is a little more stiff when breaking and turning, but I felt this helped the body roll and nose dive significantly. I definitely wouldn't say it rides rough now, just a little more stiff when it needs it.
I also did not add new UCA's with this setup, and I had no issue getting proper alignment. I am running the TRD Pro wheels and stock tires, but I am looking to upgrade to 285's soon. My personal recommendation would be to run it with your stock coils. In the future, I might upgrade my suspension again by setting the front Bilstein back to base height and adding lift springs all the way around. I would probably go with Toytec's 3/2 lift kit if I did that, but I would probably have to get new UCA's then.
