IS35007

My 06 IS350 don't have the ticking sound. But when I turn left. I will hear a very low grinding sound too. And grinding when I break. My 07 IS350 does have the ticking in the engine and that is normal believe me. Thats just the way the engine was build i guess.

I have a question IS drivers, I'm thinking about replacing my stock springs for Eibach springs. Give me your advice on this one . I want to put 1.0 front and .8 rear. is that a bad choice ?....
