E36 19" rims, HELP!

[thereisawizza]

Am trying to fit 19" ACS alloys to my 1996 3281 cabriolet, having rear clearance issues and strange noise from lhs wheel hub. Car is lowered and has stiffened suspension! Cheers.

Have swapped front and rear wheels and achieved better offset but would like to raise the suspension slightly as it is ridiculously low and still rubs on rear arches. Can I use coil spring spacers or should I get standard springs fitted back. Have seen springs on eBay for a 318is coupe but don't know if these would be any good on my 328i auto. Thanks in advance peeps!
