Questions?? RWD Sakura D4 - Understeer


I have been trying to cure understeer in this car for awhile...

At higher speeds the car used to just head straight when turning.

Now at least it bites, but the radius is ridiculous.

I set the D/R to about 25% and that helps a lot...

I have a Sakura XI with diffs in the front and rear, and that thing turns on a dime at any speed.

Do I need to add a rear diff to the D4?

Why such bad understeer?

Anybody else experience this?

It is designed to be a drift car, and won't work very well unless running drift compound tires.

I sort of figure it out... I have to be really careful when turning, and only turn the wheel 1/4 turn or less. If I'm going straight and immediately go full lock it just goes straight. But if I slowly turn the wheel its super responsive...

Now I just need a place large enough to practice.

There aren't many places in MN
