The pros are red brembos, better stance, firmer suspension, quicker steering rack. The cons are if you're old and/or frail people think it's a bit too firm. I think it's fine but I'm young and athletic
I changed from FF to Cup on my 197 and the only real difference was more rattles. Also changed to a 200 Cup steering rack and again don't think that was a significant change.
Personal preference really mate. For me it just made the car that bit more 'sporty' but when I test drove the two back to back, the standard car had normal seats and the cup with Recaros. The two together just made for a better experience.
I agree with Ralphy that your probably gonna get more rattles and a choppier ride on a bad road though....
Having come from a 172 with Eibach Sportlines the cup chassis is actually an improvement for me in terms of ride quality. But then i actually do have a cup not just a poser like the above FF owners
