+R at first was terrible in the FK2 for me and in the first year I probably only pressed it twice, it really jiggled the moobs but now it's one of the first things I press.
The responders available is a way around the ride quality in +R.
For me the fk8 appeals are the simple things, optional extras, styling mods, flywheel etc etc.
Pedal and seat positions in the FK2 have always niggled me, being tall I find my right leg twists inwards on the accelerator so I'm hoping the fk8 would be an improvement.
My cons is mainly cosmetics, faux carbon, pointless faux vented honeycomb, steering buttons, digital volume control (petty I know but I'd find it distracting), the bulky seats.
I've not written the idea off yet, I have informed my dealer to ring me asap if mugen team up again, but at the minute for me personally I feel it's to early to jump, there's already a list building of faults and niggles from the Americans including the handful of dreaded FK2 gearbox niggles.
Fk2 trade ins are terrible at the minute due to the fk8 release, dealers are offering pi$$ take deals, I heard one chap being offered 22k on a 5 month old limited black edition, shocking
