Brake discs weight?

[Lionheart_4eva]

I couldn't help but notice most fto's tend to have larger brake discs over the slightly smaller size ones with the fto. It's just that, the advantages of having larger discs is for appearance and not wearing as fast, but it also increases the overall weight of the car and the only way you can take advantage of larger discs is by having larger calipers; but i don't think a Na fto really needs that much stopping power (maybe a turbo) and should concentrate more on lighterning it as much as possible; ofcoarse your probably thinking why not just layoff aftermarket bodykits while your at it, but quite frankly thats impossible, so what r your thoughts larger discs or smaller ones?

i think standard size rotors are fine for the street and in some cases track. i think harder applications require higher spec pads and or rotors(slotted).

But in this case, i think the wieight on the rotors might be neglible, actually thinking about it now.. if the centripetal(spinning) force were to increase the extra force of say 500g on a axle that might add up. this depends on the speed you are going, faster means more force.... i dont know how this will affect handling.

All depends on what you want them for?

but with larger rotors it takes more breakign to overheat them, i have completly fried my brakes twice, once was with race brakes ! and i have to say it is the scareiest thing pushing the brake and nothing happening.
Both times were not on the track, but through a set of bends and a little bit of spirited driving.
You are right about lightening the car too, because this also helps with brakeing.
I used to think you could only stop as good as your tyres will let you, so dont skimp on tyres either

Don't mind my ignorance but I thought most people would've uprated their rotors but not necessarily increased the size of the discs themselves.

Take for example the rotors from DBA with specific part numbers for the FTO. I always thought they were the same size but with features such as being slotted, drilled, and the materials they are made from.

You are right though about the weight distribution of the car. But I think having larger calipers are the major culprit, whereas like Jono said, the weight of the rotors themselves are negligible (but of course having larger calipers usually means larger rotors also).
