I had severe grip issues on the half worn set of Michelin Supersports that was on my M5 Competition 575, when I bought it last year, lots of wheel spinn, losing traction at 50-60mph etc.
Put new Michelin PS4s on it (stock dimensions) and those grip like nothing I have ever seen.....
Ferraris and high end cars are probably running VERY high end Pirelli's such as the P Zero Corsa or Michelins Ps4s, possibly even semi-slicks like the Michelin Cup 2R tires or Pirelli Trofeo R. Meaning they have the grippiest rubber on the market.
So if you have saved some money on a cheaper tire, that is probably why you have grip issues. You can also mess it up with things like wheel geometry (camber) due to lowering giving less grip surface, wider tires is not the same as more grip, incorrect tire pressure or even a too stiff suspension setup will affect grip negatively.
I you have a car with a lowered, stiff suspension kit, 21" wheels and 305-315 tires of a "regular type" with incorrect pressure and rear wheel camber due to lowering or to fit said wheels and tires.
You will have significantly less traction than a stock M5.

My car is all stock with the exception of BPM Stage 1 tune. And I have the Michelin Pilot Super Sports with plenty of tread remaining. Even before the tune traction was an issue.
But when I drive my friends Porsche or Ferrari and floor it I feel the power comes linear to avoid slippage yet it's still enough power to beat the M.
On a positive/fun side, did some pulls against my friend's F430 Scuderia from 60mph rolling and beat him each time. If the car wasn't tuned then I'm pretty sure he had it.
