Are the rear subframes on the 3,5 & the MW the same. I know the shocks mount different on the MW chassis but are the subframes different?

I checked this a few years ago for someone else on the forum. This was the outcome.

ePER (the Fiat parts catalogue) used to list several part numbers for the subframe for different models, but numerous part number changes filtered it down to just 2 numbers for the entire range. One for cars fitted with HID Xenon headlamps and one without HIDs. The only difference was a small bracket on the subframe for HIDs to mount the rear automatic headlamp adjuster sensor on.

Can't say for sure, but this would suggest that all non HID subframes are the same, and all with HID subframes are the same.

Some of the part number changes could be because of modifications to the subframe, so I would be more inclined to fit a later one to an early car than fitting an early one to a later car.

The HID version would also fit a non HID car. The only difference is a small bracket welded to the subframe for the HID sensor rod to bolt onto.

Newer isn't always better/stronger.. it's more often just cheaper to manufacture.
