Mine used to be a v6 car.
The springs are usually lighter.
The tranny won't bolt to a v8, so being weaker doesn't matter because you have to replace it.
The sway bars may be weaker and/or not have have a rear sway bar--mine didn't.
The rear-end is the same.
The brakes are the same(unless you compare it to a 1LE setup.
For me, buying a v6 car was great because it was cheap and I planned on replacing everything anyway.
