Về cái
positive scrub radius = 17mm
Em cũng chưa trải nghiệm đọc diễn đàn nước ngoài họ bảo nó sẽ ảnh hưởng đến cảm giác lái và khi phanh.
Cái này nó liên quan đến nhiều thông số caster, toe, tyre pressure, tyre sidewall stiffness nên cũng phải nhờ bác nào kiến thức uyên thâm tí.

When you’re messing with suspension, wheel sizes and new suspension, the scrub radius can change – and it can have a big impact on your car’s driveability

Positive scrub radius does no favours for braking if for any reason there’s a different amount of force between sides of the vehicle, say, if the left-hand wheels have less grip and the ABS backs the system off on that side. This kind of setup will see the car want to fight its way in the direction of the wheels with more grip. Extreme positive scrub radius can make the steering very heavy, too, and it was only really viable on old cars with very thin tyres.
Most of us have negative scrub radius on our cars because it tends to go hand in hand with MacPherson strut suspension.
