Mostly some 20 minutes, sometimes longer. Tried to vary this but it didnt make a lot of difference.
Sometimes (when the fun driving starts) no traction compound and then it keeps the (slight) understeer.
Now I recon that if I can setup the car when it has good steering without the compound, my overall grip balance will be better, even when using the traction compound.
What compound can be trusted to woth for the complete 8 minutes?? (if any...)
I think its great that itm getting such quick responses, thx guys.
