Those tyres won't be helping.
Mine was on 245/40/18 Goodyear Eagle Assym 2s with Irmscher Stila wheels, Sachs shocks, Plod springs all round, Pedders rear subframe bushes and solid diff mounts, Rear self levelling, Pedders top mounts, Powerflex front bushes and Powerflex Black Sierra bushes as the vertical bush. Geometry was set as zero toe and camber as above.
I don't recall it understeering much, but zero toe does make it a touch vague straight ahead ( this is an insurmountable side effect of having a recirculating ball steering box as there's always a dead spot unless you are turning), but it used to turn in crisply. I enjoyed driving that car hard.
My Elite had B4s with Pedders top mounts, Irmscher springs all round, Powerflex front bushes with standard vertical bushes, Pedders rear subframe bushes and solid diff mounts, and Irmscher rear shocks with the same wheels/tyres.
That had standard toe/camber and handled as well, but felt different because it was lowered and due to the vertical bushes being stock, the front end was a bit more forgiving...
