Braking is limited by grip between tyre and ground and varies with speed.vis wrote:I think they have to fit small 13" rims to be forced to use little diameter brake rotors, otherwise with 18" or so they could fit larger brake discs and brake like hell (=more than now) (remember that super braking is one of the main reasons why there is so little of overtaking in F1...)
I know what is this guy speaking about, I first saw the effect in a music video (Metallica - Fuel) and then in a TV commercial (I don´t remember wich)While low profile tires would most likely provide a handling benefit they do suffer in one important way .. their lack of ability to store torque windup makes them easy to spin under throttle. Hence, if allowed F1 teams and tire mfrs would likely use low profile tires on the front but maintain tall sidewalls on the rear.
12.4 Wheel dimensions:
12.4.2 Complete wheel diameter must not exceed 660mm when
fitted with dry-weather tyres or 670mm when fitted with wet-weather
tyres.
12.4.4 Wheel bead diameter must lie between 328 and 332mm.
Regardless of wheel diameter, brake disc sizes are a mandated size, in both diamater and thickness.vis wrote:I think they have to fit small 13" rims to be forced to use little diameter brake rotors, otherwise with 18" or so they could fit larger brake discs....

But surely, from a ridehight point of view, it doesn't make any difference whether the vertical displacement is from the tyres or the suspension, the only difference being with the suspension you have much more control over the spring rates and damping?If the tyre takes part of displacement caused by the irregularities on the road, you can use a smaller suspension vertical displacement, in the A-arms. In turn, this could mean that you can use a slightly lower body, closer to the ground, so you get higher downforce, but it is just a thought.
That's true, but remember the spring rate for tires is highly adjustable in the form of tire pressures and carcass construction. I know that they don't actually change out spring rates of the suspension during the race and with the tire pressure they can technically do it quite easily if necessary (something that is really important during wet races).williamssam wrote: But surely, from a ridehight point of view, it doesn't make any difference whether the vertical displacement is from the tyres or the suspension, the only difference being with the suspension you have much more control over the spring rates and damping?
