How do you add extra front wheels to "*.car" file?

[Geo3]

I have found the following :

Engine: Ford Cosworth DFV, 3-;itre, 465 bhp
Gearbox: Hewland FG400
Fuel/tanks: 42 imp. gallons
Wheels: Front: Twin wheels. 10" dia. 9" wide.
Rear: 13" dia. 18" wide.
Tyres: Goodyear (special fronts with 16" OD)
Suspension: Front: Twin double wishbones with outboard coils.
Rear: Parallel lower links, single top link, twin radius rods, outboard coils.
Steering: Single rack with slave link to each axle.
Weight: 575 kgs.
Top speed: 175 mph.

Note steering (highlighted above), is directly linked from front pair to next pair, so reacts in identical fashion. Could it not be possible to duplicate a normal front layout but moved rearwards and in "car" file named "wheel-FR-2" and "wheel-FL-2" to denote different position. In my vdrift model, I have place front wheels well forward, hoping to be able to add the rear set of front wheels later......

I'll try to upload my P34 conversion somewhere...Geo.
