Heat exhanger setup

Heat exhanger setup
Right now the only heat exchanger I am running is the ZZP S3 lower bumper mount. To me the stock LSJ heat exhanger looks like it would yield lower coolant exit temps because it is thin with way more frontal area. I'm thinking this area should be more effective at transferring heat because most of the surface is exposed to fresh ambient air. Even though the ZZP exchanger is much thicker I am thinking the air will heat up as it moves through which will significantly drop the efficiency as you get closer to the rear of the heat exchanger. On top of that, air won't move through it as freely.
I have recently purchase a stock LSJ h/e from advice and am wondering the best way to plumb it in and sort of wondered how much y'all think it will help. I'm thinking it should run through the LSJ h/e first and then the ZZP bumper mount. Any opinions/advice?

h.e out to endplate in

I wonder if mounting the stock HE in front of the radiator instead of being sandwhiched in between would net better cooling.
FWIW. this weekend I logged my IAT/IAT2's using torque
64* Ambient air temp
cruising on highway IAT2 was 110-115
2nd-3rd gear pull to redline IAT was 105
Recovery was surprisingly fast
This is all with OEM stuff. only mod I have is option-b

thing you have to remember is the coolant temp in the intercooler system arent much above ambient, not unless your road racing. moving your stock heat exchanger in front of everything wont really do a whole lot. we are at the mercy of the efficiency of the laminova cores and intake manifold. dual pass end plate helps, people have seen better improvement with a single pass modded manifold. past those mods (along with the 2nd heat exchanger) your not going to see a huge decrease in iat2 temps when the coolant is close to ambient already, unless you do an ice box or a killer chiller (they dont work well on these cars).
