| This is a bit of a vague question, as there are more fatctors that you didn't include that determine when and where the car will understeer/oversteer or be nutural...... The main one would be what Springs do you have? So unless some one has the exact setup that you have then what ever answer they give you will have to be taken with a grain of salt. because if I were to have the Progress rear bar with the stock front, and say H&R sport springs. then My car would handle differently then your car if you had say, Neuspeed Race springs.
SO with that in mind, I can only speculate as to how that setup will handle. More then likely the car is going to want to bring the ass end around a lot sooner then you are use to. and in High speed corners it may induce a bit of oversteer. not that having a bit of oversteer is a bad thing; as long as you dont do any thing stupid to make it worse like Hit the breaks. |
