Havejust purchased some Focus RS Brembo setup with ST170 adaptor plates. The pads are brand new so I'm thinking of bedding them in by doing a track day on them, but my track car (Focus) runs 17s. Before I go to the hassle of trying to fit them has anybody else already tried.

Is it a case of

Yes they fit

They fit, but depends what wheels (would be ST170 wheels or OZ F1s)

No chance, you need 18s.

Ta in advance, any help appreciated.

 

I had them under 17s on a sierra so cant see why not

 

i had them on my RS2000 with OZ's and no spacers before chanced to 6 pots

 

Don't see why they wouldn't unless the wheels are totally oddball size.

 

i've had them on an xr2 under 16" rota competition wheels, bloody tight, should be better on 17's i'd have thought.

 

Under 16's!!! Jesus!

I've got 300mm ST170 discs with Mk3 Mondeo calipers already fitted, I fit a set of 16s for general moving around and loading/unloading off the trailer and the current brakes look pretty tight under those, couldn't imagine another 30mm of disc size PLUS big 4-pot Brembos under there.

Great that they should fit under 17s though, would make my life significantly easier! Will post up some pics once they're on.

 

17's are fine,
Had mine under 16 comps just to test,

 

I have them under 17,s on my s2

 

Ive got 300mm brakes under 15inch alloys lol so I would defo say they would fit.

 

They do fit under my OZ wheels!!!

Unfortunately, having spent about 5-6 hours fettling them to fit (I think the adaptor brackets I've got with this kit are absolutely shit!!! MDA Motorsport ones apparently) I've gone to refit the wheels only to find I need spacers to clear the calipers now!

They need around 10mm of spacing, which means I need longer wheel studs as well!

Gutted!

 

Hopefully you will get it sorted matey.
