Gentlemen, in my dark and distant kit car building and Escort tuning days a good way of upgrading the standard two pot caliper Ford front disc brakes was to purchase Leyland Princess 4 pots calipers,(exactly the same mounting position) modify them with the appropriate spacing kit and fit Capri vented discs. A very worthwhile, economical and practicle performance mod for a fraction of the cost the fancy aluminium jobbies that can be bought today for our Caterhams, that cost anywhere from £550.00 upwards.
I have been trawling the web trying to obtain said Princess calipers but to no avail. Seems they have died along with the ****ty car they were fitted to.
I have read on some sites that the MG Metro turbo calipers are the same type as the Princess, Can anyone out there verify this please. The deciding factor apparently is the centres distance of mounting bolts. A set of two calipers, the spacer kits and Capri vented discs can be purchased for around £260.00. Quite a saving, the only thing you dont get is the weight saving advantage of the ali ones. But I can live with that.
