Thought i should share this. Test drove a 2017 rcf today as finally there is one popped up on AT locally.
having owned the isf for over a year now, always wondered if upgrading it would be a wise decision in the long run.
probs not the best comparison but my f has coilover, exhaust and bushing.
Imo pros are
AVS: so ride is better, more well dampened. It is a better than my kwv3 set up but not by far.
Slightly more responsive in the lower rpm range
seats are more comfortable
faster ? On paper yes, street driving, Dunno i cant tell with the limited time i had it
cons imo
steering is too light and vague in comparison to the isf? It feels as light as my nx. My f is more weighted
i aint tall, 5ft9 but the seat belt is so far back after i have adjusted the seating position that i actually had to give a good turn and reach for it.
i genuinely feel cabin noise is quieter in my isf. Could be the tire in the rcf tiring.. but there was also rattle for such a new car from the rear seats. the brake being squeaky didnt help either but that is the dealers preparation
It needs an exhaust... too damn quiet stock.
