<On the weekend at Oran Park he broke 3 spokes. He check the spokes
after every session.
With competition rubber, I wouldn't be using standard wires, the dayton
72 spokes are good wheels and they are obviously not quite good
enough for serious racing.>>
No wire wheel is. If you want to run wires, with modern tires, buy new ones
and toss them every couple of years (or longer, depending on what your neck
is worth to you). They flex and the spokes work harden and crack where they
enter the wheel (they take a bend at that point).
<<When you start getting more serious (comp rubber for example), I'd be
putting knock-on alloy wheels on the car.>>
Wrong way to go as well. Some, at least, of the fancy Minilite look-alikes
are weak and break. A friend managed to walk away from the failure of one of
those wheels at speed on his E type. Fine for the street, bad for racing.
Far better to convert to studs and run alloy (aluminum or magnesium) bolt on
wheels.
I used to run magnesium, before I 'retired' to do only vintage, and went back
to stock Twincam wheels, which seem to hold up alright. Don't even think
about stock MGA or TR6 wheels - they are garbage - I've ripped the centres
right out of both of them. People don't seem to realise what stresses modern
racing rubber puts on wheels and suspension.
