I know these are prob 1 of the best tyres 4 track days to use if not the best , but are there any others that i should look at that are possibly a little cheaper and of a slighty harder compound so they would last me abit longer as unfortunatley i dont have an end less budget 4 the car...

The car will also be used on the road so i would like it to stay semi useable etc , will i really gain much on track by loosing the rear seats , spare wheel , dr cards etc ?
