|When changing wheel sizes, final drive ratios or Speedo clusters it is essential to make sure the speedo cable worm and drives are correct for the car. There are many combinations available, some work better than others, but one which is suitable for the application can usually be found.|
This is for a single pinion drive of which there are at least six variations. The tooth options are 15, 16, 17 and 18, but the required part will depend on the worm drive it is to be paired with so please detail both the tooth count and diameter of the speedo worm when ordering so the correct match can be made.
To calculate the required drive please use my ratio calculator page http://www.guess-works.com/Tech/ratio.htm.
