Just picked up an 01 is300, it has 18" sparco wheels and is at stock height. My question is, what offset should I run if left at current height and would it be different if I dropped it 1.5"? Trying to keep it as flush as possible. Thanks for any help

 

how many degrees of camber?

 

i'd think it would have to depend on negative camber

 

+17 front & +25 in the rear looks nice.

That's what I was thinking. Your wheel's offset may be stamped on the back of the wheel face or on a sticker. If you drop your IS 1.5" it will naturally camber a little. Drop it first and adjust camber accordingly and/or add spacers until you get your desired look.
