Who's shouting, it was only an example of a perfectly acceptable kit car with different track widths.

the change in track width will just change the load transfer between the front and rear axle. If I remember right a wider track would give more load transfer on that axle.
So in theory you'll just need to adjust front rear spring rates to get the balance right again.
(lowering rear spring rate or increasing the front spring rate would bring the balance back for a wider rear track, think i have that the right way round)

I think you would be best making the car wider at the front to compensate the extra rear track...longer wishbones perhaps?

Is all this track malarkey going to affect the positioning of your headlights and indicators? I know the headlights on a standard chassis are getting quite close to the front wings on full lock. This is because the light distances are taken from the widest point of the chassis (The rear wings). So your headlights are going to have to be 2 inches closer to the front tyres / wings.

Just something to think about.

If the front track is widened, the wheelbase must be increased proportionally in order to maintain the Ackermann steering geometry.

I think the Roadster already has the standard Sierra front track with a shorter wheelbase, making the front wider will throw it further out of tune.
