I need some advice. I currently have bilstein 5100’s on all four corners at 60k miles on them. I want to change out my shocks with dobinsons twin tubes with 2in dobinsons standard springs in the front and a 1in dobinson springs in the back. I plan on adding the dobinsons upper control arms as well. Should I go with the 2in or 2.5 springs up front? I was hoping the dobinsons twin tubes will be softer than the 5100’s or would the twin tubes be a downgrade? Any advise would be much appreciated!!!
