Reduce the understeer by decreasing the front axle roll stiffness and adjusting driving style. The most effective way(s) to do that is to:

A) Remove the front sway bar, or at the very least adjust it to its softest setting. You left the rear bar stock i.e. OEM, so now the front to rear roll stiffness is unbalanced...

B) Decrease the cold start rear tire pressures considerably.

C) Decrease static rear camber (less negative).

D) Set front axle toe-in to zero or slight toe-in (i.e. about 1/16th to 1/8th of an inch total toe-in at the front axle).

E) Reduce the front axle spring rates.

F) Use wider front wheels.

G) Increase the front axle track width (perhaps with spacers).

H) Use less steer angle when at the limit of the front tires by adding some over steer balance by doing the things listed above.

I) Soften the front shocks in bump setting
I am strictly here to learn:

Would a stiffer rear bar help here?
