I feel that the feeling of firmness when turning the steering wheel has increased.

● Mounting parts: Strut tower bar, lower arm bar, floor cross bar, etc.

I installed an additional strut tower bar with the lower arm bar and floor cross bar attached.
Originally it was a car with high rigidity, so there was no big change, but I feel that the feeling when turning the steering wheel has increased.
Next, I am thinking of installing a ram air intake.
