I have an extra set of is250 18s so my plan is to unstaggar the is250 and run the 18x8.5s on the is250 and the 18x8s on the rx300...i attached a rough picture of what it could look like. Do you guys think it will work- has anyone else swapped out rims other then switching over to rx330 rims which i know does work.

Thanks!

 

Update...Hub on the rims from the is250 do not match up with the rx300...so thats a no go
