I got all of my rack parts from Alex77 on thesamba.com. And he sent me tie-rods that are 1" shorter each to work with my 2" shorter beam. The rack is from a VW Polo(only available in Europe)

The rack is offset to the left in line with the steering shaft. The tie-rods are almost equal length so bump steer will actually be reduced or worst case the same as with the steering box. You can see the pickup points right near each other.
Whatever steering method is chosen, the steering box or rack must be at the correct height in relation to the steering arms on the spindles to minimize bump steer.
I drove an IM(2002 model) in 2008-2009 with the Golf rack. It worked OK but I didn't hit any major bumps, nor did I drive it in anger. The Golf rack is conventional with short tierods and there is no way that this doesn't induce more bump steer than the standard VW steering box or Alex77's rack setup.
I'll start my project in the new year, I have all the parts prepped and painted. I think that I'll possibly have to trim and re-glass the area immediately above the driver's feet.
Stay tuned...
