Speedtech Subframe?

[Roadrage David]

The DSE and Art Morrison front subframes are both front steer rack & pinion, The SpeedTech subframe is rear steer. I'm wondering if one is preferred over the other. Logically, a front steer arrangement should be stronger since the tie rods would be under an extension load rather than a compression load.

Mij gues is that due to the rear rack and pinion in the rear there is room for the Pontiac engine???
