For road racing; I run non power for all of my Vws. Locked diffs with turbo torque steer is not an issue for any of our drivers. My steering wheel options go from 14 iin to 16in. The Mk 2-3 have a pretty good scrub radius that seems to allow welded diffs and non power.
The A1 Rocco with welded likes the really big steering wheel. . Nonpower will work /drive fine at road racing speeds and tunr radius,IMHO
