Traction control

[marcus]

I have a question about traction control that im hoping someone can answer for me.

yes I hate the thing and it should be banned but for the cheating thing i guess for now it wont.

But after attending Albert park on friday I noticed alot of differences between the systems just in the sounds of the cars.

are there different systems available ?

for example the majority of the cars from where I stood it was only slightly noticeable but on the Minardi's it was very pronounced , you could really hear the traction control working and working hard compared to the other teams.

Is this just a case of other teams spending more money on the system then them or do they completely rely on it at a higher level than the other teams ?
