Track 'rubbering' in
Discussion
Gents, I thought I'd throw this open to the Pistonhead masses to see if I can get a better understanding.
Hows that work then?

The track is getting better now the rubber is going down after the Porsche Supercup this morning
Now, I thought that the rubber going down from the Porsches would just add to the rubber but he aluded to the fact that the F1 cars would be ripping up that rubbish rubber and laying their own down.Hows that work then?
Simply because the F1 rubber is different to that used by the Porsches.
F1 cars go out and lay rubber which helps the F1 cars go faster.
Porsche cars then go out, lay down a different rubber, which doesn't suit the F1 cars.
F1 cars then go out again, slowly replacing the rubber on the circuit with their own!

That was the only thing I could come up with in my head, so cheers for that!F1 cars go out and lay rubber which helps the F1 cars go faster.

Rather than the Porsches laying down their own rubber, I thought it was more that they're a much heavier car running a lot harder rubber. This means they don't lay down a lot of their own rubber but the F1 rubber on the track will stick to their tyres and get worn/torn away, so they're effectively "cleaning" the track surface. In essence, I suspect there's less rubber on the racing line before the Porshe race than after.

I would be inclined to agreed with this, but not the logic of your final sentence. There is less F1 rubber on the line after any other race because of the cleaning effect.
Track rubber is actually crucial to performance.
I race 4stroke karts at the same track where 2 stroke karts race. we have four heats and a final they alternate with us for track time and while we are off they do their heats and final.
However as they get quicker during the day after the second heat the tracks slows for us as their rubber starts to get laid down.
They have softer rubber than our tyres. Our tyres are harder because we have less power we don't need the amount of grip the 2 stroke karts have.
Because we have less power to drive quickly we need to have ironically less grip to go fast so that the solid axle at the rear end doesn't 'fight' with itself and 'bog' down the motor.
As they day goes on our tyres start to pick up the softer rubber from the two stroke karts and then our speed decreases as our chassis start to tighten up.
Under normal circumstances after a days testing our tyres have a matt sheen and a clear smoth surface. After sharing with the 2 strokes they resemble more something that has had hot candlewax dripped all over them.

I think you will find that the Porches etc. dont use the same line as the F1 cars. You only need to look at the track to see loads of rubber laid down in places the F1 cars don't go anywhere near.
There may be the odd variation but the racing line is the racing line, they'll all be using the same line within a foot or two on 99% of the track.Forums | General Motorsport | Top of Page | What's New | My Stuff
