The Princess-style brake caliper is a kitcar favourite. There are some companies producing upgraded versions including Hi Spec Motorsport 

The standard Princess caliper is designed to use 245mm brake discs (or ‘rotors’ for our North American readers), which can cause dreaded ‘overlap’ issues with performance brake pads. I know I’m definitely not alone in experiencing this issue.

Rally Design has just launched a potential saviour of this issue with their 257mm discs available in plain face or performance cross-drilled and grooved. They are available now from £91.73 inc VAT per pair.
