Different front and rear track

[Talonmotorsport]

I thought about the spacer Vs wheel bearing problem and came to this conclusion, the donner sierra weighs 1100kg (ish) was made to carry 5 people, with 120kg of luggage towing a caravan weighing 1000kg. The roadster will prob weight not much more than 750kg (steel panels and lardy me) and will prob not do more than 3000 miles a year. So if the wheel bearings last 2-3 years so be it.
As for the shape of it looking odd you should see some of the heaps I've taxed over the years. I don't realy care what it looks like to be honest as long as it's road legal ,drives in a straight line and passes an MOT.

So front to rear track being different any body know the answer, will I need more camber and caster?
