Why the change in suspension in E90 from E46

I used to stunt drive my 02' 325 all day on 2 wheels. I updated the model for a more "show" look and little did I know the difference in the front control arms and a frames. Seems BMW went on the cheap after 06'. I bent my lower control arm twice and had the strut pull from the mount. I tried to update everything since the car did have 90,000 miles although even with new parts the car failed again. I know they are not made for this type of use but my input and findings are the e46 are made for more abuse (racing, drifting) and not just for soccer moms. I enclosed pics and would love feedback on what you guys think. I just spent 1,2000.00 on upgraded parts and am going to make a control arms that are stronger this time. I'll give it one more shot. I am amazed by the difference in wheel support between years. Thanks for any feedback and what you think is the issue….

Two reasons (at least):
1) Lighter means better fuel mileage
2) RFT tires

The non-M arms are made of rolled sheet metal. They are weaker and flex more than the M3 arms.

M3 arms are machined from solid aluminum, flex much less, and are overall more durable. I do not know about the strut top design but I imagine the rubber is of a stiffer material.

All the M3 suspension arms are a direct fit to the RWD E9xs.

On xDrive, AWD models, only the rear arms fit. The front needs modification for the M arms to fit. Most likely due to the front AWD diff setup/subframe

I think it also had to due with costs. Rolling aluminum is cheaper to manufacture than CNC machining parts
