I s there a big difference between the standard car and the Ti in terms of ride comfort?
In my humble opinion yes. I know Damien on here who has driven my car and thought it was fine, but he is used to a LOT
firmer suspension on some of this other cars. (Damien do you want to comment?).
Personally if you're driving on bad road surfaces (like I do a lot) I find myself looking for the best set of tracks on the road to place the wheels on.... It becomes very tiring. Also, when the roads surfaces are poor, the car jars
and feels skittish. As the tyres wear the car will tramline slightly too on certain roads.
The 40 profile on the firmer (all be it slightly firmware) suspension has no advantage, as far as I can see, on the normal car with higher profile. Looks are a different thing, but day to day living, comfort and the cost of the tyres I can't see the advantage.
The only advantage can see is on a motorway at speed, the car does feel very well planted on the Ti setup. In high crosswinds (again this is my experience) there is no buffeting.
