Cup+'s on Rear, Cups on Front - Problem

[sailorbaz]

Just done the above after snapping up a reasonably healthy set of Cup+ Rears off Ebay, but didn't bother fitting Cup+ Fronts as the Cups I have for the front have plenty of meat left on them.

However, after a short test drive there, I mean short only a few hundred yards around the Estate, the car felt as if it had major clutch slip in 2nd and into 3rd and also when slowing down for a junction, it was if the car would disengage the clutch completely, like coasting. Which didn't feel nice at all. Any ideas of a simple solution???

Reset SMG thing with the paddles at 40mph and all that Jazz???

Kick it's hole in on a decent couple of mile run?

Any ideas welcome as I was hoping to wear them to the Ring this weekend but if she's going to play silly buggers, I'll have to put the FK452's back on, which themselves aren't too bad on track but was looking forward to having the car back on Cups again.
