I am looking into changing my rs1 wheels, i want to get the exact size...anyone know the specs or where to get them without removing the wheel?

 

What kind of Enkei's are they?

 

not sure what the style is...they came on the rs.....there is a pic of it in regional rockies....in stevinson east car show pics...of course its the red xa...i would just put the pic here but not sure how to do that

 

i crawled under the rear and the wheels are 17x7 offset 30 now i need to see if the wheels i want with offset 40 will work...
