[Yardeeee]

My issue I had with BB tyres was that some of the rear greens were too soft... I am not so sure whether it is a case of the fronts being too hard, and whether the big difference between front and rear is caused by the rear softness.
some of my new BB green rears felt rather pink and I ran a set like that in leg 1 and 2 of the A on the saturday (2wd, at this point I wasn't using BB fronts) and my car was pants... leg 3 I switched back to a harder pair used earlier in the day and it was fine.

The variance in compound front to rear will have a big impact on balance regardless, and if the fronts and rears are labelled as the same compound they should be. Having said this, I had only 1 problem all weekend with the BB tyres as mentioned previously and will remain on the fence in this situation.
