S2 rear tyres

[Blu S2]

Off to Le Mans on monday which should just about kill the original tyres which have done 12,000 miles so quite pleased. What do people recommend as the best replacement ie stick with original tyres or are there better options, also what a bout prices, anyone advise.

Fronts still have a plenty of life left in them so need to think about mixing sets, again advice appreciated.

Thanks
