....there was a period where the choice was Ferrari or Cosworth....then there were Turbo's vs normaly aspirated. There used to be only one tire goodyear, then there were periods where you had goodyear and pirelli or Firestone or way back Dunlops...Why stop there, Ferrari use Brembos, Bar uses Alcon.....

I'm for less restrictions not more. Otherwise you end up with CART or IRL<p align=center>
