This didn't go on my 2nd gen IS. I put it on my 1st gen IS. IS300 spacers WILL fit the IS350.

Haha, I was looking at that site this morning... I called them but I guess it was too early. I'm actually ordering some 25mm for my rears - the offset (for stock 18" wheels) is quite extreme once you drop the car. The gap from tire to fender is a tiny bit over 25mm.

Are you usr its about 25mm on your rears? Seems quite a big gap? Post pics please. ..

I think your measurements might be off. If I remember correctly, the stock rear wheel has a 50 mm offset, and a 35 mm offset winds up being VERY close. I have a 18x9 with a 35 mm offset and stock tires, and I can't believe it doesn't rub.

Considering the fact that you will have to put much longer lugs on it to even do a test fit (a major PITA), I would reconsider the plan.

Thanks for the replies, everyone... I have no idea what the stock wheel offset is, but I was instructed to measure the distance from the tire to the fender. I taped a piece of string to the fender with some washers tied to it to create a plumb line, and measured the gap from the tire to the string. Did I measure wrong? I got 20mm for the fronts, and 25mm for the rears. Thanks,

Did you do this? How To Measure?

The widest point of your tire and wheel combination is usually the outside diameter of the tire sidewall. Using a ruler with the straight edge flush with the face of the tire, measure the gap between the outer face of the tire to the inside lip of the fender as shown in the diagram. This will determine the thickness of the spacer you will need.
5MM = 0.197 INCH
8MM = 0.313 INCH
10MM = 0.393 INCH
12MM = 0.473 INCH
15MM = 0.590 INCH
20MM = 0.787 INCH
25MM = 0.983 INCH

Were you measuring to the inside of the fender liner to the outside edge of the tire? The outside edge of the fender (painted surface) really doesn't matter.

Ah, I measured to the OUTSIDE of the fender - this will probably add 5mm to my measurements...

so can someone give the amounts of what one would need to get to make the stock 18s flush with the side of the car. i would like to purchase these right away.

I measured 15 mm from the outside to the inside of the fender.

10mm front and 15mm rear would be the most you could do and definitely not rub with stock wheels and tires.

I'm measuring my stock rims (front and rear) and I measured 15mm. I'm not sure if this is the right number can anyone confirm this?

So I'm 5mm off at the front. Thanks
