O.K. Here it is after the cut @$$ with changing my rear shocks, when I drive and hit a sharp bump or pot hole the tyre still rubs slightly. I have come to realization that my tyres may be to wide, but the thing is I've seen other soarers with rims the same size or larger. Currently I have 235/45/18 on the rear, and the car is at stock height. What else can be done to eliminate "THE RUB"?
if the springs are stock, take them out and measure the height of them with a known good (new) spring if they are shorter they have probably sagged and no longer have the same spring rate as when they were new this could also lead to the car bottoming out and (rubbing the tyres) because the spring has lost its original spring rate...
ps. you could also measure the rear height of you car and compare to another known good car again if it has stock springs and the car is lower they could of sagged..
if this is the case time for some new springs!
since as you said it only rubs on big bumps i would say this is the problem.
All wheels have a pre-determined offset, they can't be adjusted. The only way they can be adjusted is by a) Welding additional metal/skimming excess metal (heard of it being done, not worth it) b) Spacers (they will only subtract the offset... eg. +41mm with a 20mm spacer = +21mm overall)

If you feel inside the inner lip there is quite an edge there , if you have the plastic edging like the Celsiors have you can remove it and trim the inner lip off , this will give you almost 10 mm and you can't even see it . If you do it with an angle grinder with a 1mm thick cut off blade and don't force it you won't damage anything . Just make sure you clean up the ragged edge on the inside of the guard or the first time some one runs their fingers under there they will slice them . Just as note about spacers , if you drill and tap the spacer to the hub with two 6 mm counter sunk screws , then it's not a spacer anymore as it's attached to the car !! That's why the disc on the front and the disc/drum on the rear have two screws in them to hold them to the axle , other wise technically they would be spacers as well .
