I've had a play with a JDM DC2 that a mates got and in a straight line there is hardly anything in it.
The DC2 would eat my FN2 in the corners though.
Remember that the BHP isn't everything, gearing makes a big difference too.
Honing your driving skills will probably be better than trying to mod the FN2.
Everyone likes to think they are a good driver.I'd like to think I'm a decent driver , However all the races we have he always seems to pull away. He can even take on an EP3.
