The ride heights in the manual are approx. It can Be plus 0.5" base on may actual installations from FJC and 4th Gen 4Runners. So, by adjusting it to say 1.75" it can actually give you 2.25".
alex56,
I have no idea when combined with OME and Spacers LOL!, but the stock setting of the shocks which is the first notch/grove will give you precisely stock height. Should there be a difference, its because your suspension have already settled. So you will still get the same lift as you have now.
Your Setup : Factory Shocks(0" lift) + OME 884 and Spacer(3"lift) = 3" total lift
Plan Setup : Bilstein set to Factory(0" lift) + OME 884 and Spacer(3" lift) = 3" total lift.
How about setting it to .85" and install just the OME springs. It might give you a little over 3". But Bilstein warned against installing it with aftermarket coils and not setting to minimum height...I don't think there is a problem.
