I currently have 1" wheel spacers on my 03 cobra from the previous owner. I am buying a set of FR500's- 18x10's, with the BFG Dr's, 295/35/18's.

Question1- Do I need a spacer with the FR500's. I know that the 1" is too much, but I have heard of people running a 3/8" spacer with this wheel size/tire combo. Is it necessary?

Question 2- I currently have a 1" spacer. Am I correct in assuming I will need to replace the studs that are currently installed for the 1" spacer if I go with a 3/8" spacer, or no spacer at all? If so, what studs do you guys recommend?

Thanks for any input.
