can a sub frame from a 2003 Monte Carlo bolt on to a GP?

i was working on a 2003 MC to day and noticed some thing the sub frame was aluminum i think that would save some waight conpared to the steel one we have

Found this searching.. apparently the second poster (I think? or third) says they work together.

Yes they will work together. You have to use your LCA's with it though, and I think add a hole here or there to hang/support the power steering "cooler" line. Other than that, direct swap over.

Tad bit weaker than a stock steel one, but you save a few pounds.

But it's weaker... I'll stick with my 3900000 pound steel for safety...

Yes your saving weight. But there is too downside, safety goes VROOOOOOOM *CRASH*, and you lose some ever so important stiction between the road surface and the tires.

not really. i am kind of thinking if any racing maybe auto X (but i would be put in a non stock class so i would have to get a stock car to drive for a while). but other then that mayber one or two passes a year down the drag strip

Thats a few pictures of a good aluminum sub frame.

Here is a picture of a bad one...from a pretty big pot hole...


Bet that felt good.

Anyway...switching for a weight reduction for drag racing or even AutoXing I fell would be a wasted investment in both time and money. Nothing wrong with the stock older steel ones, as they can take a good beating. Plenty of problems with the newer aluminum ones.

Good about the steel is if its bent, you can see it...aluminum...a lot harder to see the stress flexing of the frame. Most salvage yards anymore will not resell the aluminum ones for them not knowing 100% if its straight or not for resell. They will scrap them most the time.

But what ever you want to do. I thought about switching mine, but as hard as I drive my car, I decided I would stick with my stock steel one. It is ugly, I agree, so while it was out during a tranny swap many years ago, I had it powder coated for like $150.00 in a metallic mirrored silver. The control arms I finished where GM left off with their spot welds, and full seam welded them, for more strength, and had them done in red. Both look pimp...when your under it.

that bent pic of the aluminum one is what mine is doing on the pass side


well i was going to build up the suspention next and was just wandering. i figured since it was coming out any way i could lighten up the front a bit.
