Different front and rear track

[mr henderson]

The Tiger Avon is substantially wider at the back that the front, and doesn't have any known issues. I can't rememeber the actual difference, but it is a lot, well over 100mm IIRC

Thing is, what really counts is the distance between the insides of the rear wheels. A lot of 7s I've seen have a fair bit of clearance between the inside of the wheel and the outside of the chassis, so you may not need much spacing (or offset if you change the wheels)

The Tiger Avon aint much to shout about though ...

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)

from my experience wider front track gave better handling in the wet

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.
