hey,
ah ha, i think i see your problem, i have 20inch incubus paranormals which have a rediculously huge offset and lowered on SL's which means the wheels scrub like buggery. all i did was attack the rear bumper (plastic bit) where it joins the metal guard with an angle grinder, a dremel, severely roll the guards and it only scraped on the odd occasion when there was a fully load or a really big bump. next i got it lowered on SSL's and i ended up getting the part that attaches to the hub on the car machined down about 3mm and it very rarely scrubs at all.
i would recommened guard rolling, then modifying(cutting) the rear bumper/ guard, then if only your last resort get the rims machined and only a little bit like 1-3mm at the most, but this is illegal and highly unrecommended and could be unsafe and dangerous.
cheers,
George
