I disagree. If you follow that logic then nobody should lower their cars, even a non xi.
H & R now has a lowering kit for the xi. I think this is big news for anyone interested in lowering their xi. Also check with E90post member Getagrip. He has a lowered E46xi and has E90xi on order which he plans to lower as well. He would be a good resource for you.
