UPS rang my doorbell today... :)

wow...19x9.5 +25offset still need 15mm spacer, so if i have 19x9.5 +37 offset, it means no spacer still perfect for my rims?

You're going in the wrong direction. The larger the offset, the more the wheel sinks into the car away from the outside edge of the fender. Try to visualize this. If you have a wheel with a zero offset, that means the hub is right dead center in the middle of the wheel (if you were looking down at the wheel from the top, vertically). Now let's say you have a +20mm offset. That means the hub is pushed 20mm out towards the outside of the wheel. But what happens when you mount it? The further the center of the wheel is pushed outwards, the more the entire wheel will sit inwards when it's mounted. The offset for the stock 19" rears is +30mm. So if you wanted to push the wheels, say, 10mm out towards edge of the fenders, you would deduct 10mm for a target offset of +20mm.

Those are more narrow than stock sport pack wheels.The offsets dont compensate enough for that either. It isnt going to look as hot as you think.

True they are more narrow but only by a half inch. You can still use the same 245 front and 275 rear rubber without stretching so.....

Not only that but if you look at a bone stock 370 like mine here you'll notice that the stock sport wheels aren't sitting flush with the fender to begin with. Now I'm going from a stock offset in the rear (I believe it's +30?) to an offset of +25 will have it sitting just about flush with the fender if not back in the stock postion. I actually think it will improve the look over stock.



I know that it may look desirable to get as much meat as you can squeeze into a wheel well but what you gain in grip is countered by added weight and drag. Frankly, I don't think you'll even notice any difference whatsoever from behind the car.

But.. there's only ONE way to find out right?? I know I know.. working on it...
