The rear mount ear flexes towrads the other side.

Adding a sinmple lateral brace will help support the loaded ear from the opposite rear mount ear bolt. I need to reroute my exhaust (will be building a custom setup in the near future (next on my list) and then I will simply add longer rear control arm bolts ou thte backside of the subframe and attach a lateral brace from trailing arm tubing and rod ends. It will have a very slight rpeload outward to take up slop and then locked down to that length with the jam nuts.

Below is a pic of the subframe, and then the same pic with a lateral brace supporting the rear ears.

It's well known that W202 (& W201's) sub frames do crack, might be worth doing a bit of research on the net for a few photos. Consider some extra welded in bracing (using rebar or similar) and rewelding the original joints too?
