M3 Front Subframe Support Bar Question

Hey all. Coming over from the depths of General e46 to ask a specific question regarding the brace that triangulates the front subframe to the car frame.

Part in question: 51717893609



ZHP part in question: 51717028433



On the Non M produced after 2001, there is no place to lift the car from the center point below the engine. On my 328i there is a jack point under the oil pan that looks to be in the same location. As far as I know the ZHP I have recently acquired doesn't have that central lift point. And because it doesn't have a belly pan I thought why not buy the parts that come from the M3, because I noticed through some searches that there looks to be a center lifting point on your brace. And while they are different shapes, the mounting points could be in the same area.

Let me know if you can. If you know a definitive answer that would be great.

Either of those underpans will work, you'll find a few extra holes on the M3 pan but also will likely find the M3 underpan to not be as robust as the non-M. Atleast when I compared the M3 pan to the non-M pan the M3 felt more flimsy. With those extra holes in the M3 pan you'd be able to use M3 FCAB carries and then get extra mounting points to attach to pan to, bolting the pan to the FCAB carries(non-M's don't have this).

The other thing to think about would be access to the oil drain plug, which if you went M3 pan you'd probably need to drill a hole to get at it easier. Lastly, I'd never recommend jacking up the car from the oil pan, but if you have the old triangle brace I'd guess you could jack from some point on it but honestly don't know.

I toyed with the idea of going this route when I built my car out, but ended up going with oem non-M parts for this area

Just go non-M. BTW, that pan you list for the "ZHP" isn't a ZHP specific part. it's for all 01+ 325s and 330s. nothing to do with zhp

Re: M3 Front Subframe Support Bar Question

Thank you Anton. The 328 brace has me spoiled. And I'm not sure, but shouldn't the jack point be directly under the front subframe?

I've never jacked up the front of the car another way, but I'm aware of different techniques. Just want to make this as simple and quick as possible.

welp, on either of those pans you can see the M3 you'd jack from the rubber puck, or the non-M from that raised area in the same location as the rubber puck. The non-M might bend a little at that jack point but those are the locations I've always used to jack up my car to get jack stands under there. You probably already have it figured out, but if you're low drive up on some wood blocks to get the clearance to fit the jack under there.
