Thanks to eviltwin, I was able to get these...
swapped my stockies with no tyres for his stockies with goodyear eagle F1s. took it for a run today and realised my old federals have seen the best of their life. so i cleaned them and stored them next to the wall outside the house.
i'm going to swap the tyres over tomorrow at the tyre store. come track day, completely go hard and destroy these tyres to give me a reason to buy semi-slicks for the next track day...
