K-Sports are notorious for having 'track ride quality', as in not very good for daily drivers. But it varies from application to application. The VDub guys LOVE their Kontrol Pro version... but Kontrol Pro's get a LOT of hate on the Maxima forums.
I'd find someone with a 3 that's rocked the KSports and find the opinion.
I love my KSports, but I was looking for a stiffer suspension setup.
My wheels don't rub at all. A LOT of measuring went on before the wheels were ordered. They couldn't have been any better as far as fitment is concerned. I can dial in 0 camber up front, and not touch anything even on sharp turns. I run -1.3 camber right now with no problems.
And Hebrew, your accord is looking VERY nice. Great stance, love the choice in wheels and tint really sets it off!
