ive got 15inch wheels on my escort ,it only wieghs just under a ton but with 6pots on front and singles on rear seem to work well,hi spec they are, but braided lines through out and the hi temp brake fluid,all helps but seem to do the job,oh and no servo so you can feel what there doing,
i know people prefer ap and brembo damm good brakes but its just the price that puts you off,plus not much available for my size wheels
