2 Inch Lift questions! Please Help

Hey guys thanks for looking. I have an 03 Tacoma 4x4 Ext Cab. I have Toytec Coil-Overs with the Bilsteins shocks underneath that are adjustable. It appears to sit pretty much level with the replacement 2 inch shackles I installed in the rear:

I just order new wheels and tires: 17 inch XD Spy Black rims on 285/70R17 Nitto Terra Grapplers. I think I will have minimal to no rubbing with these tires on my current set-up.
However, I really wany to lift it more. I think I can probably get close to another 2ish inches out of my set-up in the front. So I was thinking i would do that and do an AAL in the rear or put it on blocks, most likely AAL's. My question is do they make a rear shock for 4 inch lifts? The extended rear shocks I'm seeing online say they work with 0-2.5" inches of lift.... If anyone has the Toytec Coilovers like this:

Does anyone else have this set-up? If so what is the max height you can get out of it, if you dont have any modifcations other than this to your front end? What would you guys reccomend doing in rear to get that extra 2 inches or so, and what shocks work with a 4 inch rear lift?? Thanks a ton!

 

Prepare for a jaw biting spinal compressing ride. Those are meant at 2.5" lift maybe 3" max. Even at 2.5" the coilovers start to get stiff. With those stock rims you have I can almost guarantee they are going to rub due to the backspacing and width of the new tires. Even if they don't run you are ass close to the UCA's.

 

You won't get much more out of those coilovers, maybe half an inch... Looks like you have a bit of front to back rake so an aal may be a good addition. Bilstein has a longer rear 5100 I think toytec has them available.
