If you have stiff front springs then there is less requirement for a stiff front bar since you have already significantly increased the stiffness of the front.

But for a road car with softer springs a stiffer front roll bar works very well especially when matched to stiffer rear bar. My car definitely understeers less than before and can be provoked into oversteer on tight turns.

The very stiff rear bar you have fitted will equalise the front stiffness by increasing oversteer / decreasing understeer.

I assume once you have the stiff rear springs fitted you will need to soften the rear bar to reduce oversteer
