Bought a 2011 e90 328i. Rear subframe replacement?

I bought a 2011 e90 328i. It had what appeared to be minor rear right quarter panel damage. I had the car towed to the repair shop. I noticed a bent right front inner tie rod. I ordered a meyle hd. $53 delivered Delivered the car to the alignment shop. I am told that the car has a bent rear subframe. They canít do an alignment. Arrrrgh. So it looks like I am going to have to replace the rear subframe.

Questions .

1. It looks pretty labor intensive,
2. I see mentioned swapping out bushings with m3 bushings.
3. Should I consider swapping the bent subframe for a m3 subframe. If so what other parts have to be changed vs could be changed. Any downsides to swapping for an m3 subframe?

Anything else the check.

It is a 328i. Pretty plain car. No xdrive, no nav, basic bmw professional stereo. No performance upgrades so far. For now I just want to get it to a drivable state.

So much for my easy fixer. ***128512;. The interior is immaculate. Exterior looks terrific, except for the right rear, which is almost fixed.

Thanks in advance.

Phil

You might try going to a collision repair shop to see if they can straighten the subframe. Or check out some junk yards to see if they have an undamaged subframe. But you would incur the expense of removing that used one and then R and R your existing one. Try Ticsher BMW to price a discount subframe. Getbmwparts.com

I can get a used subframe from a local wrecking yard for $45. Is the 328i subframe different from from the m3 subframe. Does the m3 subframe usethe same subframe with different bushings. I can feel myself slipping down that slippery slope........Thanks. Phil

The wrecking yard had the std rear subframe for $45. The m version was $500. They couldn't tell me the difference. Phil

Subframe is a big job. I agree you should get a second opinion, from a good body shop.

Cross check the subframe with the part number in realoem.com. Something like that may have the BMW PN stamped on it.

There are several PN's for this. https://www.realoem.com/bmw/enUS/sho...diagId=33_1229

The M3 upgrqade kits I've seen are just bushings. Here's FCP: https://www.fcpeuro.com/products/bmw...33326763092kit

They don't have tire rods in the back. Some other name?
