Hey I know you guys are going to think I'm completely stupid, but I don't care I'm going to ask anyways. Could anyone please explain the difference between a 40 and a 42 offset on an 18" rim? Do either of them need modification to fit? Will either of them rub when turning? Does one sit further in then the other? And yes I know there is a section already explain offsets but it doesn't make much sense to me, so can someone please post explaining the differences and would anyone be able to answer my questions? I'm planning on ordering my rims any day now so I could really use the help. Thanks
40 and 42 offsets won't hurt you any. As long as you get the right sized tire you shouldn't experience any rubbing. Quite honestly, offsets don't matter much in our J's.

depends on your suspension your running. some can run offsets that others cant. me i like my 48mm offset since i have bags it brings the wheel closer.
basically the lower the number the farther out the wheel will sit and the higher the offset the farther in it will sit. what is the width of the rim your plan on getting?
thats the wheel - Zinik Z5 Ikeda - Chrome - 18" x 7.5" - 42 - 5/100 & 5/115
thats the tire - Yokohama Parada Spec-2 - 225/40ZR18 92 W - BW
and my suspension set up is koni yellows with gc coilovers
thats fine you wont have a problem at all
You won't have any fitment problems but they will probably look sunk.
And here's an explaination on offsets.
The offset is the amount (in millimeters) the mounting face (where the actual wheel meets the hub of the car; in the center of the wheel) is in or out from the center of the wheel.
A positive offset (which pretty much every car runs, but more so for FWD, +35, +40, +42 are common) will bring the mounting face out further toward the front or face of the wheel, making the wheel sit further in the wheel well.
A Negative (or less positive, i.e. +20, +8, 0, -10, etc.) will place the mounting face further toward the "rear" of the wheel, making the wheel sit further from the car.
