Slow suspension build questions

Hi im still pretty new here, I have a 2015 tacoma 4x4. I'm looking to achive more clearance, I bought 2in spacers for the coilovers to hold me over temporarily, what are so positives and negatives to that? I'm also wonderin if there is a way to slowly upgrade maybe the front suspension first and move on to the back? If so what are some recommendations? Is it a bad idea to do it that way?
Also wondering about tire size. Can I go a size or to up from 265/70/R16?

 

I would do it all at once. Do it once, do it right.

As for the tire size, are you willing to trim and cut if necessary? 265 is the biggest without cutting.

 

You can definitely do front and rear separately. Many people do spacers, you'll be fine - they're just not ideal. I'd say upgrade the rear next, since you spent money on the front already. Get an aftermarket spring pack that lifts you slightly higher than the spacers. Then later on, when you have the money, get new coilovers for a better ride and more articulation with your lift.
