You know,..you'd have to say this IS a somewhat 'Moot' point anyway,..as having had a 'Glance' over the 2009 Australian PlaFit rules,..it would seem the Body choice has been clearly 'defined', as to Brands that are 'Homologated',..sigh,..Lancer Bodies even !!!,..They would have to be Re-Pops, Unless someone is prepared to 'Race' an Original !!
Tom Anderson Bodies,..Probably the Most to scale out of the Bunch.
So unless someone has 'Carved' themselves some New Original renditions, many of these 'Current' bodies would be 'Back Pours from 'Someone's Shell from the Past and as it Really Has been a Long, Long time since either the Poms or Yanks actually Raced 'True to Scale' lexan bodied cars, one would possibly question the absolute Scale accuracy of Many of them.
I'd be More worried about How to Fit the required Wheel Diameters under some of those bodies !!
With the exception of Tom Anderson's bodies, Obviously Sunset and Lancer, I have Not heard or am aware of the Other Bodies on that list. Obviously the Scale/Plafit guys are aware !!,..lol
One would think some of the Current and Past Betta bodies would be eminently suitable and probably HowmetTX's bodies.
One would also think that Victor ar True Scale would be interested in some 'True Scale' Replicas !!,..lol
Electric Dreams has occasionally mentioned Re-Pops of some of the MESAC bodies, like the 917LH, which were from my Memory Very Accurate Scale bodies.

to the GoodYear Racing 'Eagle' Sports Car series of Tyres, (the pdf has dimensions listed).
As an Example, the Spec's of the G19 Tyres, (a 15" Slick suitable for CanAm cars) is as follows;
the 23.0x10.5-15, is 23.4" in Diameter, with a Section Width of 11.8" and a Tread Width of 10.4"
the 27.0x14.0-15, is 27.0" in Diameter, with a Section Width of 18.5" and a Tread Width of 14.8"
That works out at;
24.77mm for the 23.4" tyre's Dia and 28.58mm Dia for the 27" Tyre,..Bigger than Ya'd think Huh !!??
an overall Width of 12.49mm and 19.58mm respectively,..Wider as well eh!?
A 13" Rim, is 13.76mm and the 15" 15.88mm, with the 10" and 17" recommended Rim Widths being 10.58mm and 17.99mm
