im about to order some Ro Ja Formula 5 18x8 all the way around off set 40 will these fit?

 

Not very well. I see rubbing tires in your future plus you can't stagger the tires either.

STOP! RO_JA makes the Formula 5 in S2000 offset, I know, I had some for 2 summers that I just sold. They have 18x8" front with +55 offset, and 18x9" rear with +60 offset. These are pretty close to perfect offsets. MAKE SURE TO ORDER THESE PROPER OFFSETS!!!

Those are sweet looking rims! Good luck , and definately do not go with the same size all around!!!!!! The S2K is meant to have staggered rims from the factory and otherwise
