Bilstein 5100s vs Wescott Collar lift up front?

[ThatSickRIp]

Was wanting to do the WD preload collar up front just to level my 4R out, but then was thinking about just swapping the stock shocks with 5100s. I cant see labor being any more since they have to pull the whole unit out and apart for either option.
Any issues that I might be unaware of with just swapping the front shocks and leaving OEM rear? Im only got about 800 miles on it so far.

I was able to purchase on FB market place for Red Bilstein shocks with the Wescott preload lift kit with only 2500miles for 400$. I couldn't pass up the deal last year. But if i couldn't find a deal like that i would just get 6100's. If you don't wanna pay up for the shocks. I was on an RC front 2 inch level kit with no issues for 6 months.
