Want to improve the front brakes of our Starlet, but retain existing struts and 13" wheels. Have slightly larger Corolla discs which fit straight onto Starlet stubs, but the 4-pot Austin Princess calipers I have are way too wide. Can anyone suggest suitable 2-pot calipers (both pistons on inside rather than opposed to each other) or alternative that will suit the narrow un-vented Corolla discs, stub mounting and disc offset. Any suggestions would be appreciated.
