How can u tell that C5's are real.........Real meaning actual Racing Hart Rims...thanks

 

and are 18's too big for a lx 4door 5th gen accord?

 

18's are a bit big heavy, but with a good drop it will look fine. You can tell if they are real by looking on one of the spokes, and it will say "racing hart"

 

18" are pushing it. I would go with a 17". If you can look at the rims they should have a RH or Racing Hart stamped in the back side of the rims if infact they are real depending on how old they are. The evolution series I believe has R.H.E. stampped on the back.
Some body correct me if I'm wrong here.

 

I think if you look on the back of the rim and on one of the spokes it will say "RH".
