I've found that the outside edges of front-mounted tires wear quicker, while it's the inside edges of rear-mounted tires. Rotating side to side won't help with that wear pattern--you really have to switch front to back.

By not "flush", do you mean the wheel will look rececessed or stick out?

How did you find all this offset info and what will/won't work for the car?

PUR NRG - I forget to mention that by having bi-directional tires, I plan to rotate the tires in a "cross" pattern; back to front, front to back, but that's if I get the same size Rim all around. If I get staggered size, then I have no choice but to go from left to right. I'm planning to get Staggered size rims.

Also, if wear becomes a problem, you could always adjust the toe and camber to compensate for the wear.

When I said by "not flush," I meant the wheel will recess "in" the fender

Last, I actually spent some time at my friend's performance shop and we mounted various size rims and different offsets to find the best matching set. We also measured the mounting and our conclusion were:

Best Option - For 18" or 19" - 8.5" in the front w/+45 offset, and 9.5 in the rear w/+44 or +45 offset. You could also go +42 in the rear.

so is it beter to go with a bigger offset in the front?
should i switch the offsets to +45 fron and +43 rear?

i want some 5zigen FN01R-C in these specs
18x8.5(front) +38 18x9.5(rear)+43

maybe somebody can help me out here. i don't know what im doing.

sup3rbad - the smaller the offset number for example, +38 vs. +43, the further out the rim sits, which means too much offset would cause your car to loose handling ability and your rim to rub against the fender.

So, the set you want to get, 18x8.5 in the front, should have no less than +44 offset, otherwise with a +38 offset, it'll rub.

You should get 18x8.5 +45 offset (front), and 18x9.5 +40 or +42 offset (rear).
