It has to be called an "Upgrade Kit". It is not that Fiat has decided out of thin air that certain parts can be changed/replaced and increase in GC can be achieved. I am sure there is certain amount of R&D behind this "Upgrade". If there was no R&D, it would never have been an official thing. By making it official Fiat is providing you with a certain kind of warranty regarding the parts (Please do not confuse it with parts warranty). It is the R&D that is ensuring that you do not lose the handling and ride. Let's take an example. If you get an aftermarket suspension, and get it fitted through after market sources, who will be held responsible if something goes bust? Answer is quite obvious I guess. Now, if you had paid the manufacturer of this after-market suspension, he will surely look after you if things go bust. Now in this case Fiat is providing you with something it is calling an "official upgrade" which means Fiat will be responsible for it. There is a price to pay for that isn't it? So i really am not convinced about Upgrade kit and MRP equation. In my book, it is a good offer and I am up for it. Of course many Fiat owners will not want to go for the upgrade and that is their call.
