Echoing the others here.

Door rattles means something is loose and/or the vinyl is rubbing against the sheet metal. Take panel off, replace all clips, secure anything loose and install (take great care to be sure each clip finds its home and doesn't get smashed - this is very tricky). Then, I use small snippets of felt between the panel and sheet metal junction to eliminate "creakage". Your doors should make zero noise if done this way.

Ride quality does get very very bad in these cars if everything isn't tip-top. Shocks and tires have by far the largest impact. V12s are soft but only when new-ish. If they're worn they suck, as do most tires. And, you for sure need new shocks.

Thanks for the replies guys. My rear tires are actually bald, maybe thats why its so harsh? I am getting new rears this week, so ill see what effect the tires itself have on it. Also gonna check the shocks and springs while the wheels are off.

Should I go with stock shocks or aftermarket? It looks like 4 OEM shocks are well over $1k in parts!

I'm contemplating this also. My ride height is 1/4" higher on the rear left so I might go lowering springs and Bilstein or similar for aftermarket shocks.

So I got new Hankook Ventus evo 2s on the rear and WHAT A DIFFERENCE. My rear tires must have been screwed, cause now the ride is so much better now! I also had them slightly lower the PSI on the rears as well.
