My last car had a built-in bar, so I never upgraded it to an aftermarket bar.

I see alot of people with SC400's and they have the bar, I remember I didn't look for one for a reason, when I got the car alot of people said it didn't make to much of a difference.

I see the Cusco and some other ones popping up on the classifieds too, not sure why sometimes.

Do these bars make a noticeable difference in the SC400 chassis?

Will you notice the difference right away?

What would I be lacking now or notice later with a bar?
