Track Dimensions

[Swiss_Toni]

Does anyone have front and rear track dimensions?

In any case, how should it be measured?

Is it wheel outside, middle, inner edge or wheel mounting face on hub????

[V8Dom]

id ask the factory direct..

each car might change depending on if bushed suspension or rose joint?

may i ask why you are asking?

[Swiss_Toni]

I'll ping Richard an email. Though if anyone had the info it would be great.

I need the track for the maths channel on my MoTec data logger to calculate oversteer on the traces.

Now why anyone would think a 715bhp Ultima would oversteer may come as a surprise to some... or perhaps not.

From the nice people at Ultima.

For MY car.

Front track 1545mm
Rear track 1475mm

Front overall width tyre to tyre 1805mm
Rear overall width tyre to tyre 1845mm

How would your car differ from most? do you have long or short wishbones? Id like to give theses measurements to my geometry people incase its useful....

[Swiss_Toni]

It has standard wishbones with rose joints, I suspect it would be similar for most but I would want post to say it's case for ALL Ultimas of all ages and configuration.

rose joint suspension different to bush

however Tony

depending how many turns into the wishbone each rose joint is placed will change the overall width of the car.

unless the factory built your car and the geo hasnt been changed , id run a piece of string over the wheel sideways with a plum weight on it onto the floor... mark with a marker pen on the floor.. this will mark max width at the wheel... then for each wheel and then move the car forward and measure with a tape measure

we could also argue is the factory measurement of hub centre or max width due to camber>?
