I was originally going to do a DIY on installing coilovers for the IS350 since i did not seem to find a single guide online. However, i went into some fustrating problems during the installation and didnt follow through with the pictures.

Overall, i am happy with the coilovers, they ride very similar to stock, and no noises.

However, i followed the tein manual, and it said to raise the coilover 1 inch all around, but i found the front is significantly higher than the back. (the back actually can tuck the tire) Also, i noticed the headlights aim VERY high now, which i thought AFS was suppose to auto adjust itself? I did remove the AFS sensor (i think it is the AFS) during the rear driver side, but i put it back. i might have messed it up ? Anyone know? (My AFS light did not light up)

 

yeah i did have the same problem. the front for me was noticeably higher than the rear. i just lowered the front about 3/4" and it solved it. sorry i dont have AFS so i wouldnt be able to help you out on that
