Hate to say but that won't last long. Not to mention how many other parts you will need to change out to support it. Near gearbox, new clutch, new intakes, injectors, exhaust etc.
Try first the small things, poly-bushes on the wishbones (control arms), lowered suspension, stage 1 remaps, they take it to 130~ hp and are already on the edge of gearbox/clutch ratings.
Lowering springs; (if its auto you need the other set thats meant for the heavier engine/gearbox)

Control arm front bush; SuperPro SPF1915K
Control arm rear bush; PowerFlex PFF85-1202
You can get a SuperPro rear bush, but i'm unsure on part number, i've got the superpro/powerflex combo on my control arms and it made a HUGE difference to the feel of the car. Smoother and more responsive at the same time, make sure you get it realigned/tracked after having those done though, it slightly alters the alignment.
