The ultimate with the historic race guys seem to be the Hoosiers...Serious $$$$$$
$1000 a set.
You would get about 2 good race days out of a set....works out about $10 a lap in tyres around Queensland Raceway!!!
Next option seems to be the Yokies A032R Still $$$$$$

but less wear than the Hoosiers.
A very very close 3rd would be the Dunlop D93J (Formula R).
Much more popular than the Yokies as they are only $125 each fitted. (What I am using!) Wear rate seems to be similar to the Yokies. Only problem we have with these is that they have no real 'shoulder' on the tread and they tend to scuff the outside edge off when pushed hard and are unidrectional (hard to rotate around for even wear)
The other you could think about is the Dunlop R7 Sports. It is made from the same compound as the Formula R, but has a decent shoulder on the tread like the Yokie A 008 and the tread pattern in not directional. Same $$ as the Formula Rs. It won't be as good in the wet as a Formula R though (Not for Targa Tassie I'd say

)
I am not a big fan of Dunlop the brand (Too many problems with their normal road tyres

) BUT.... bang for buck you really can't go past them
I will most likely be giving the R7s a go for my next set of tyres

(Unless someone warns me otherwise

)
Talk to Dunlop Motorsports at QR on 07 54619100. Their not far form you
For what you want I think you would be spending too much money on the Yokies...Go the Dunlop Fomula Rs...save your money

Ps. Don't forget that the dunlop tyres only have about 30 heat cycles in them before they become as hard as they will ever be.
