This is a bit of a funny thread.
Sure singles do the job, but there's just something about the way twins work in GTR's that makes you think they should come standard.
Launching time after time, hard changes, positive feeling on changes etc - SO good!
I regret selling my nismo twin, have an os giken triple plate currently, as soon as nismo increase the c spec twin to handle 800hp ill be back with one of them.
Cant compare os giken to nismo, sure they both feel good by themselves, if you dont believe me, do a test back to back. Nismo will win.
With that said there's also some quick GTR's on tricked up singles.
End of the day, its personal preference, and out of all the GTR owners i know, only 3 have single's.
