the 430 has a sport suspension switch, change it to normal and the ride is not rough.. I cant roll with the thing on Sport all the time cause thats like driving a loweres isuzu pickup lol. but its fun when your haulin a$$ around corners on the highway.

My dad has the 350 and i noticed that on his as well. i dont like it.. my 430 however does not knock like that.

Do you have the 07 version and will the 07 version work in my 06 430? I cant message you for some reason in here. I am interested in this. please send me more info crd589@hotmail.com.
