The mileage of my SVX is 113000 miles.
Therefore, my SVX has been maintained during about two months within one year.
SVX is improved between those.
The color of my SVX is blue of Skyline GT-R(R34).
Bilstein badge is "Emblem Tune" in Japan. The batch was only pasted.
This suspension was made in the LUCK.
