That size should fit the Focus ST without any issues. I'll need a total of 3 people to place a $200 deposit to get this going. All orders will need to be identical in size color and offset. It will be $999+shipping for a set.I was wondering if the 18x8.5 with a +40 offset fit the focus st and also interested in a price for the hyper black with royal lip in the rota mxr-f. Plz pm me. Looking to buy in the spring.
