Stiletto Steering Systems
Over fifty years ago a legend was born. Stiletto Steering Systems is the industry standard for race car steering. Stiletto rack-n-pinion steering boxes are the gold standard benchmark of driving control.
The wide selection of purpose-built Stiletto steering boxes are known for their smooth "Swiss Watch" movement, ease of use and unparalleled durability.
We’re not going to tell you how it works or all the finite steps required to produce a product of this caliber—just know that Stiletto Steering Systems continue to win more races than any other and bring drivers home for the next pass.
So, if you are looking for the smoothest operating, safest, most proven steering rack and components you are in the right place. Expect nothing less than near perfection from the team at Pro-Werks.
Built with out compromise in the USA.
How to Determine Steering Ratio
The overall ratio of a steering system is determined by the degree of the movement of the front wheels in relation to one turn of the pinion or steering wheel. Example: One turn of the steering wheel (360º) divided by 30º tire movement would have an overall ratio of 12 to 1 (360/30).
This overall ratio is determined with the distance of the rack travel created by one turn of the pinion and the length of the spindle arm that the tie rod connects to. A shorter steering arm will result in faster steering and the overall ratio smaller numerically. A longer arm will result in slower steering and the overall ratio larger numerically.
For reference purposes, the ratios that we list are calculated using a spindle arm length of 5 inches. This is the distance measured from the center of the spindle king pin axis to the center of the mounting hole for the tie rod.
20 : 1 = 1.570” of travel in 1 rotation
15 : 1 = 2.094” of travel in 1 rotation
12 : 1 = 2.618” of travel in 1 rotation
10 : 1 = 3.141” of travel in 1 rotation
6.4 : 1 = 4.712” of travel in 1 rotation
