ARABLS430

Hi all, I have a 2001 LS430 with 20"x8.5" rims. I wanna lower it but not by more than 0.8". I really don't want it to be too low so it doesn't hurt the car. I know that eibach springs only lower it by 1.4", but I believe it is too much especially with 20" rims. Therefore, what kind of lowering springs you guys recommend? Thanks
