Hi i got the above to fit to a trackcar car that i was told would be able to run these but they dont fit

The disc's have been test fitted nothing else and sell have the stickers on them the pads are still in the box! They are for a 2wd Cosworth so 283mm by 24mm using the 4 pot calipers, had them to long to send back so anyone like to make a fair offer before i Ebay them. The clutch isnt for sale tho as its a Escort RS2000 unit
