This is a terminology for wheel alignment. The minimum tire scrub is the minimum " scrub radius " (as describe below) for the alignment of the wheel, so that during corning, you can have better control of the vehicle.

Steering Axis Inclination (SAI)

SAI is the measurement in degrees of the steering pivot line when viewed from the front of the vehicle. This angle, when added to the camber to form the included angle (see below) causes the vehicle to lift slightly when you turn the wheel away from a straight ahead position. This action uses the weight of the vehicle to cause the steering wheel to return to the center when you let go of it after making a turn. Because of this, if the SAI is different from side to side, it will cause a pull at very slow speeds. Most alignment machines have a way to measure SAI; however it is not separately adjustable.

The most likely cause for SAI being out is bent parts which must be replaced to correct the condition. SAI is also referred to as KPI (King Pin Inclination) on trucks and old cars with king pins instead of ball joints.

I learn everything by heart, never with formula or rules. After all, my brain doesn't have gazillion bytes memory!

I kind of admire those people who can remember all kind of formula and rules. How can they do that?

Wow!, I thought Yugo is extinct. You still have one is really amazing.

As an amateur mechanics, I think I will stay away from Yugo. After all it named you "go" not it "go". I take that as "you walk and it stays".

Melon dude must have learned the Lambo's SAI by heart.

Alright, Lambo lover - how about the SAI of my 1988 Yugo?

Nope, Yugo was still in production till the 2008 down turn - you just need to know where to find.

Psst - do you want to buy a nice used Yugo? Or Brooklyn bridge I have too...

A Yugo or amego, could be a good go if you take good care of it.
