I was able to purchase the strut tower bar and floor cross bar from the Auto Exe website, so I installed them at a relatively early stage.

After installing it, the steering wheel became noticeably heavier, the center felt firmer, and the pedal became more effective in corners.
I felt like it started to feel a little more lumpy, but now I've gotten used to it and it seems normal.

The intake suction kit was replaced at about 71,000km, and the car is currently running about 7,000km.
Immediately after installing it, I felt that my footing after stepping on the accelerator became lighter, but I quickly got used to this and now I don't even notice it anymore.
