What is the 15 1 steering ratio?
The front wheels typically turn a total of 60 degrees from full-lock left to full-lock right. A 15:1 steering ratio means that the wheels turn one degree for every 15 degrees of steering-wheel movement. This means that the steering wheel has to be fully rotated 21/2 times to turn the car from one extreme to the other.
Is a higher or lower steering ratio better?
For a manual rack and pinion steering system it is desirable to have a moderately high steering ratio to provide an almost direct steering response while the steering wheel is in the normally ‘central position’ for straight ahead driving and for very small steering wheel angular correction movement.
What is the steering ratio of the WRX?
At the same time, the WRX also features an impressive electric power steering system that boasts a 14:3:1 or 14:4:1 steering ratio.
What is the steering rack ratio for the STI?
13:1
The 2015-2021 STI has the quickest steering ratio of any Subaru product to date — it’s 13:1 compared to 15:1 on older WRX and STI models. This rack will bolt directly in to any 2008-2014 WRX or STI.
What is the steering ratio on a Subaru?
16.5:1 Steering Ratio.
Is a higher steering ratio better?
For a manual rack and pinion steering system it is desirable to have a moderately high steering ratio to provide an almost direct steering response while the steering wheel is in the normally ‘central position’ for straight ahead driving and for very small steering wheel angular correction movement.
What is the steering ratio of steering rack?
A steering ratio of x:y means that a turn of the steering wheel x degree(s) causes the wheel(s) to turn y degree(s). In most passenger cars, the ratio is between 12:1 and 20:1.
What is the steering ratio of a Subaru WRX?

How do you find the steering gear ratio rack and pinion?
we can calculate the gear ratio of rack and pinion in the following way:
- Take the pinion to one end of the rack.
- Move the pinion towards the another side of rack till it completes one full revolution.
- Calculate the distance travelled by the rack in inches.
- This is required gear ratio of rack and pinion set.
