Lowered Steering Rack on the 415 and 415MS

At the 2004 Worlds, it was noticed that Marc Rheinard was running his steering rack on his MS lower than the standard position... this warranted a bit of further investigation (lower CoG you see ;) )
In the original kit (and MS for some reason) the spacers used to postion the steering rack had two above and one below the bell crank. At first it would appear that Marc simply moved all these spacers above the bellcrank. However there are a few extra bits that need to be looked at too....
If the rack is simply dropped, then the steering links would now be in a more slopped position, this would introduce bump-steer into the steering... not nice. I know from personal experience that this can make the steering very twitchy and hard to drive consistantly. To avoid this it is recommend to add some spacers under the steering ball stud to raise them back up to there original height. Placing an extra 3mm of shims under the ball stud put it back into the same position as before, as the whole rack has been dropped 3mm.

The above picture shows how the whole mod should look on the car.
