But... I wouldn't recommend increasing the aft size much more, if you don't increase the front size as well.
Let us imagine you put 245/35 in front and 295/30 aft. Aft grip is increased, so you get better traction when accelerating. Forward grip is not increased, so you get understeer the rest of the time, altering the balance of the car...
So I think it's nice for the looks, but bad for the driving !!

What is the effect on the speedo with going to these sizes? Does it knock the accuracy out by much?
I can get stock size PSS here in the UK or the sizes you mention above, but I'm not sure which to choose....
