We've already discussed this on here, but I'm sure the sports suspension is more than just different roll bars, I think the springs are different and wouldn't be surprised if the shocks are too. After driving both suspension setups I don't believe the roll bars are the only difference...
Its funny how subjective this kind of thing is! I don't mean to pick on this post in particular, but I have 17" runflats with sports suspension and yes its firm, but in no way does it ever rattle your teeth, so I've no idea how the standard suspension could manage it. I do 60 miles a day in it and its not the kind of suspension that tires you.
At the end of the day you've just gotta try the cars out, if you drive one with standard suspension and your happy with it then great, if not go for the sport its much better
