Hi Everyone,

Iv been looking into fitting a set of st170 front brakes to my frst,

I have been getting a range of answers so thought id ask the people in the know.

Im aware you have to drill out the holes on the hub to 12mm, but i am unsure about the offset of the disks and weather the calliper will need spacing?? I know the Mondeo ones do but I want st170 as I have the rears on a mk5 beam ready to bolt on.

Is there anything else I have to consider?

I have 16`s and coilovers so clearance isnt a problem.

Hopefully this will put the issue to bed once and for all.

Cheers

Can't remember but be very cautious with rear discs as without bias valves the rear is vastly over braked. To be brutal I would say keep the drums.

I did Fiesta ST150 brakes on my old Fiesta RST and pretty sure it was a bolt on conversion.

Thanks,

Iv just brought a bias valve the other day so hopefully itll be ok.

st170's should just bolt on after enlarging the bolt holes..

Chrisfrs

Cool thanks.

Now I just need to find out about plumbing it all in. I think a couple of T pieces are in order

Cheers

sorry to revive this near 6 year old thread but i suppose thats what the search button is for.

im looking at upgrading the brakes on my fiesta rs turbo to the st170 set up and just want to clarify whats needed

obviously calipers/carriers/pads and discs, then iv read above about enlarging the bolt holes, Any idea of what size the bolt holes are drilled out to?

also are there any other bits n bobs needed for this conversion as when i do it i want to make sure to have everything at hand to sort it in one go

any help/advice much appreciated

holes are 10mm at moment need drilling to 12mm, apart from what you have listed thats about it apart from upgrading to braided hoses

Thanks for the reply mate

That's great I was actually looking at getting a set of braided hoses. I take it just get normal rs turbo ones?

the fitment on the 170 calipers is nothing special so most hoses fit, not sure what fitment connectors the frst use tbh as some years since I had one, but I do sell a lot of 170 calipers

brilliant thanks for your help mate much appreciated

Are you fitting the rear discs aswell? I've fitted st170 all round mine but I must say that rear discs are more of a visual thing rather than better braking if you don't mind the look of drums I'd just keep them on the rear

I've got st170 brakes all round, I fitted a mk5 rear axle to my fez and the rear st170 brakes bolt straight on to it, and the mk5 is a lot stronger
