Best way to get a 3/1 level with Fox setup

If i was to buy these would the best setup to get a 3/1 be to add two CB shims to each side with each coil maxed. Then whatever size CB shackles to get the rear up 1 in?

You can always contact @Coachbuilder1 and he can lead you in the right direction.

 

You would need to add shims. Between the cost of those fox coilovers and the shims you could get new boss coilovers from Toyotec. Then just get a coachbuilder #2 or #3 shackle for rear or an add a leaf.
