Cheap track day rubber A008R's x 4 £40

[Car 13]

Yokohama A008R tyres 185 60 13

with about 2mm tread ideal for track use, I bought them as advertised as A008 tyres but when they arrived yesterday they are A008R which I cant use as only allowed MSA1A tyres in race series

 

I paid £40 so looking to get back what I paid.

 

3 of tyres usable I has slight damage but would do as spare?
