Bigger offsets.

I'm so mad! I cant figure out how to make bigger offests on my wheels...I've tried using styrene.. I've tried cutting out the rim...oh my gawd...Its so hard.
So if you can give a brief or descriptive way of making them....
Thanks

Have you considred using pegasus sleeves like the ones hiroboy used in his how-to. Never used them myself but everytime someone here does they turn out perfect.
P.S. for you wing your looking for in the classifides, have you looked at some of the jada or musclemachines import diecast cars in walmart. They have some similar to that on there mrs and eclipse. I'll have a look at the car I'm tearing down right now for parts for my next project.
