The inside wheel well encroaches on the clutch, brake and gas peddle space and the passenger foot space is reduced by the VW wheel well. Also, because of the dimension differences, in the pan based build the driver's seat is not centered over the steering column)."
George, There are a number of differences, some getting closer to the originals and some farther away; I actually believe that the IM and Beck cars have more interior space than the originals, so I wouldn't necessarily call them "closer to the original", just different.
Something else to consider is that there's just so much useable space under a 356 replica body. If the interior is pushed out to provide more cockpit space AND the wheelbase and track width remains the same, then the space within the wheel wells has to decrease, possibly meaning reduced turning radius when running larger tires - just a thought.
As to clutch/brake pedal clearance issues, I haven't seen much interference on CMC's or Vintages between the pedals and the inner wheel well. What DOES get in the way a lot on these cars is the bottom of the fuel tank cavity. If it were an inch higher up I think a lot of us would be a lot happpier, especially when we step on the brake and our foot hits the inside body!
On the steering column, I'm not convinced that the off-set column is wrong. I've driven original 356's with the exact same steering wheel off-set, so what is correct?
Just my 2 cents.
