Lotus 27 - Antipodean Style

As original, the fronts a tad narrower, the rears a tad wider than a Formula Ford, assuming that the mandated FF wheel width is the same as it is here. The tyres have changed more!

Something like Dunlop R6 tyres back in the day?

Yes, R6s...

There must be photos around showing the tyre sizes used, but I'm sure I remember seeing 5.50s on the front and 6.50s on the rear.

The tyres on Scott's car at Symmons in 67 (in the shrubbery) are demonstrably wider than those on Arnold's car in the OP

Top shot James,

whereizzit tho, which corner?

Mountford...

Look at the size of that roll bar!

Not being up with FF I feel the RIM width is 6" and has been forever. Rim size does not denote tyre size

They have used no end of different tyres over the decades, starting here I think with Olympic GT radials in the 70s.

Some tyres have been proper race tyres and others street tyres. Desperation generally though has been the same.

The original F. Ford rules in the UK mandated (excerpt from May 1967 RAC bulletin) : -

10. Wheels – Only steel disc type with a maximum rim width of 5.5 inches  (ie Ford Cortina GT wheels)

18. Tyres – Racing tyres are not allowed-otherwise free within standard production retail range as specified in section 1 of R.A.C. tyre regulations.

As I recall, the common choice at first was the Avon Wide Safety GT crossply , a road tyre that had very race tyre characteristics such as a flat tread area.  I had some on my Mini Cooper S and they were excellent.   I think later the Firestone F100 was preferred, until racing rubber was allowed.

Not a problem, BRG...

The car's never been a FFord, it has alloy wheels anyway and Lee wasn't aware of that. Formula Ford hadn't started in Australia before Longford was gone.

Yes the car is a ANF1.5 Formula Lotus 27 - the same Arnold Glass car which features as James Lambert’s opening post of this thread.

Ron Lambert’s Longford shot inspired this article, my attempt at a piece about the ANF 1.5 class;

That would be ANF1½, Mark...
