The FN2 Mugen RR is more suited to daily driving than the FD2 Mugen.The Mugen FD2 is suited to the track but would be hopless on a long country winding road with all it's pot holes,uneven surfaces and undulations.
One's spine would feel like jelly after 1/2 an hour!
The FN2 Mugen is actually better at dealing with not so perfect roads than my FN2!The FD2 would simply be left behind!
