Car is most likely rolling too fast at the front so all the weight transfer is being lost in roll rather than pressing the tires into the ground. Seen this sort of thing many time and people go softer and softer in the belief that soft = more grip and it gets worse and worse.
Opposite to why some people will soften the roll stiffness in high grip conditions to get more weight transfer lost in body roll and reduce the chance of tire loading induced grip roll.
Stiffer oil, maybe increase spring too, raise front ride height.
Get it to the point where you are under-steering equally all through the corner from entry to exit then add a little weight towards the CENTRE of the car (I found between servo and slipper mount to be the best place to move the weight distribution forwards to get it back to where you need it to bring the steering back. Don't reduce mass from the rear else you'll be in spin city.
If you then find the car struggles to hold it's line late in the corner and darts in reduce the length of the front link starting at the outside end first.
As a rule of thumb on Kyosho small bores and a 2wd car if your far from 500cst / 350cst oil (±50cst depending on track surface grip level) Fr/Rr on 3b pistons with a silver front and yellow rear spring you are really wrong on either weight distribution or roll centres.
Ultimately on slick surfaces you'll be looking for an RB6 as it has more front end and generates loads of grip in the rear too
