SuperGT/DTM How are gt500 cars so fast?

So my question is basically this, how are gt500 cars so quick while still looking like normal cars. I mean the lmp1 cars looked crazy and ppl tell me that the gt500 cars would be faster at Fuji speedway so how is this possible.

Also if the gt500 regulations really are that good at speed then why weren't they used as a basis for lmh regulations? We could have had silhouette hyper cars going insane speeds.

A lot of downforce. The tyre war also helps.

Underbody downforce? I don't see a lot of wings or aerodynamic appendages and the cars are able to follow pretty well

I assume so? LMP1 cars get a lot of their downforce from their body and ground effect so I assume its the same kind of thing. Also they put down about 650hp and have anti lag so that helps.

Do you mean anti drag.

Not in this case as Super GT cars don't have DRS. The engines have large turbos so they need anti lag to always be at optimum pressure. Its also very aggressive in these cars which is why I mentioned it.

Don't forget packaging. I forget which race, but basically there was once a car who's whole front fascia came off from some contact, and you don't even see the engine cover, it's just a jumble of ducting and vents and it's all compressed looking which makes the front look more lmp2 underneath the fascia. Like their engine packaging game is damn good.
