A REAL SP car is nearly a a road race car minus a race engine and steroids!!

I have a different opinion of ST* because our region has 20+ STS cars per event including past National Champions and ProSolo National Champions cars and drivers. At least 4 STS cars are trailered to our events. The top SP cars in our region (we have the FSP National Champion) all have had their engines worked on and prepped to the limit of the rules - basically race prepped. And hell - our STOCK cars have erasers for tires since stock and SP share the same tire rules.

At what point is a "change" a "mod"? I'm not going to argue semantics.
As for the fluid - that's an old racers trick. Basically the thicker the diff fluid the harder it is for the spider gears to work independantly. But the ultimate I've heard about is using sawdust in the diff fluid. Yes, I'm serious. Yes, it works. I wouln't use it for a 100 mile trip but if you are looking for that little extra grip for one or two autocross days and know how to change and clean a diff yourself - it's not like the wood is going to wear out the hardened steel...
