Hey guys,

I am a new member here, and i am getting my moms 2003 LS430 pretty soon... I drive it quite often and love it..... It has 150k miles on it, and when i pick friends up they ask me when i got the new car.... Car is PERFECT. theese things last forever!


I also have a e46 m3.

Are there any modifications i can make to make the suspension a little bit stiffer on the LS?

 

L-Sportline springs just installed them in my Ls430 and rides more stiff and looks better

 

I would suggest not to make any modification since it is new and under warranty. It is not wise to make this step at the moment....Ask your dealer if you wanted to add some performance parts before doing it.. In my case, i've done several mods but not on my new car, I got some rancho performance parts installed, really gives performance gains.
