does my tacoma sit lower than others?

I've been reading on the tsb for the rear and I noticed the other day that I only have 2 curved and 1 straight. Where after the tsb its 3 curved and 1 straight. How much lower does my truck sit versus other trucks that's had the tsb done. Everything else stock. I would possibly get some bilstein 5100 for the front just not sure what do do for the back. I think I've seen some add another leaf to the back after the tsb to get more lift. Still a newbie at all this.

 

You get about 1" lift (in the rear only) from the TSB springs (access cab 4.0L).

Other configurations (Double cab, reg cab, 4cyl) may vary
