Not too much to say about the coil spacers - personal choice for you to make. I just thought I would point out the need for rear bump stop spacers, or new bump stops, or both, when running larger tires. ...Since you mentioned tire rub. You should be fine (with your current offset) using what has seemingly become the standard rear bump stop mod. I have 32.3" tires, 0 offset, 8.5 wide wheels, and as you can see in my avatar I am able to achieve good "stuff" into the rear wheelwells without rubbing at all. I think just about all the lifted VX's are using the same method I did nowadays. Happy lifting!!
