I wonder how will this handle...would it be understeer like ****....I know to keep the car neutral balance is 130 lbs of spring different between front and rear...and i'm pushing it to 150lbs different...Keep in mind...I dont autocross, I do high speed turns....car is gonna be use for high speed most of the time....

Anyone running anything near this? share yo opinion...thanks...

 

Those are pretty stiff spring rates for the street. Have you changed your suspension before?

I don't think it would understeer that bad. I think you should pay more attention the proportionate difference between front and rear rather than the absolute difference.
