Drifting Steering Ratio
Steering Ratio
Im setting my fc3s up for some up coming drifting events an i came across a drifting article in a magazine which read that the car had two extra teeth machined into the steering gear. How is this done and what is used to do it.

Year? model?
Usually the simplest way is to swap the steering rack with one that has a higher ratio, but many of the S5 FCs already had the higher 17.4 to 1 rack so the next step would be using the 20 to 1 manual rack from a S4 and dropping power steering.

A friend of mine who drifts said that they machine additional teeth into the rack to allow the tires to turn further out. If you are competent I'm sure an angle grinder could be used to cut some teeth in there.... I've never done nor plan to do this... so more help I can't be.

You can't do this mod on an FC power steering rack. The rack is already cut to it's maximum travel, and trying to make them go further is going to be a royal pain in the *** and/or compromise safety of the rack itself.
I dunno about "spacers", but we're repositioning the steering tie rod mount point on the hub itself, and this seems to get the steering angles that the S13/S14's are getting on the track.

And the ratios were
20.3 to 1 for the manual rack.
15.2 to 1 for the S4 (and S5 Vehicle speed sensing) power rack
and 17.4 to 1 for the 89-90 GTU, 89-90 GTUs, 90 GXL, 90-92 convertible, 91 coupe.

You need more? I Find the ratio is a bit too big when drifting.
In order to do that mod you can't have a power stearing rack. (one of these days I'm going to break down and just swap the dam PS out.) Untill then, it's eazy parking for me. :P
