I am currently looking to upgrade my brakes on ym mk4 fiesta, i was wondering if the mk5 zetec s callipers will fit? if so how easy is it?

 

Hello and welcome to pf. What size wheels do you have on your car. Ive got a ford puma and have 300mm ford focus st170 front discs and mk3 mondeo brake calipers which fit under my 15inch wheels. I had to trim the calipers with a grinder though.

Fiesta zetec s brakes will fit. You could also fit fiesta st 280mm beakes without any mods.
