Hello, I need to replace some parts on my 2003 330i ZHP suspension due to rust. I've been trying to find the exact part listing of what makes it a ZHP suspension but haven't found it just yet. I wouldn't want to replace a part with a non-ZHP part if possbile, even though eventually I will upgrade the suspension, but thats down the road. If I can replace these front and rear hubs etc from a normal E46 330i, it would be much easier to find the parts. Thanks
