Good point Andrew.
Ben, when I had a TT I found due to the weight balance of the car with full trim that running a large differential between front and rear gave the best balance.
I was running 40psi front and 36psi rear on factory 16's street tyres on the street.
Perhaps you could also try lowering the rear tyre pressure by 1-2psi and see how it goes.
I would also be looking at transferring as much easy to do so weight as possible to the rear of the car.
