Hey Viva----glad to hear you too have joined the "bigger is better club"---at least in the front brakes thing.
If the complete front end swap would have been possible I'd have done that instead of piece-by-piece but sadly it just didn't happen.
Have to give a tip of the hat to BrianW----he worked with me getting this into motion---great help at the time!
Several times recently I've had to stand on the brakes and its a great feeling knowing there's quite a bit more stopping power under my foot now.
FWIW my '00 E250 has rear drum brakes whereas my '03 does have discs---not sure what model year that change came into being. Given disc brakes relative ease of maintenance and replacement I love 'em.
I was kinda under the impression the E450 frames and rear axles were different enough things like sway bars wouldn't fit? If one from the E450 chassis fits my E250 I'll have one of those pretty quick. I'm currently running a Hellwig rear bar but would love something even bigger---ride comfort isn't an issue or concern.
Wheel-wise I'm okay with the stock steelies----love the dog dish covers too for some reason.
