Replaced my 4.11 to 3.89 diff. Now I can stay longer in each gears..,

Hi all.
Too much negative offset front wheel will effect the handling?

I think no. The most negative offset that will fit is not very much. Skinny tires will affect the handling more than the offset change

my front strut is from bluebird 910. which is already widen the front track + 13x7" deepdish wheel + w50 ball joint. rear wheels track is much shorter.

in parking, if i press the brake and turn the steering wheel, its almost impossible to turn.
I feel oversteer effect in cornering, even i don't step on gas pedal.

front: bluebird standard oil absorber + progressive/dual rate coil spring from B310 EGI
rear: sunny B11(130y) standard gas absorber + progressive/dual rate coil spring from B310 EGI

anything wrong with these set up? or do i need a good wheel alignment ?

For front, I welded the spring seat 1inch lower. For rear is standard height. Different height will make the car tail happy.?

In my experience lowering the front of a car 1" has not caused oversteer or any noticeable handling problem

YES, make sure the toe-in is within specification. You can set that yourself. If it solves the problem no need for a full alignment

alright. thanks.

btw my tire size is 175/70/13.

i removed rear sway bar to paint it white. while driving without rear swaybar, i can notice significant reduce in over steer. feel like the car no more tail happy.

# 23mm holly rear sway bar. came with b310 egi.
