as far as i know russ they are only available in 18,s ,unless you can find an old set .

they are available in et 35 for saffs and 3drs and et 15 for escort cosworths

you will definatley need a a et35 on the front and maybe you could space them a little on the back.tyre size is a bigger problem on the 3dr s and you may need to go to a 215/35/18 which look a little stretched imo.
you could try a 225/35/18 but the tyre choice is limited
