they are 324x28mm discs, ive been told i need different caliper brackets, anyone got any info on fitting etc?

Thanks, Joe

 

i've got 300mm st discs they just fit with a few mods to the calipers, so i don't think the rs ones will fit

 

What did you have to change on the calipers?

 

grinder only needed for 15's

 

ive got st170 300 millers and they just fit behind the 16's on mine so i doubt that the focus rs ones will fit behind 15's

 

you will need 17s to cover 324mm discs, however some 16" comps may squeeze over them!

 

Mmm I'm not looking to get new alloys at the moment so I'm trying to find the biggest size discs that will fit under 15's!

 

300mm is your biggest ,i cant get 16" comps over my frs set up on my s2 so have to run 17"

 

As said above, 300mm ST170 with a slight "skim" seem to be the best bet... They go under 16s with no probs!

Why not look into a brembo 4pot setup using the 300mm discs? For instance a Peugeot 406coupe uses 305mm discs with 4pot brembos...

 

i have cossie 4 pots to go on but they seem to much hassel at the minute, im going round silverston so need a quick replacement for the time being!

P.s what do you mean by a slight skim?

Joe

 

just have the 4 pots machined shouldn't cost that much

 

i have fitted 309mm discs and ap calipers under 15" wheels.

 

Didn't realise the 300s would fit under rs turbo 15s,
Deffo going for them if they do.

 

So to get this straight, Do focus st170 discs fit straight on without any modding? i take it i can use erst calipers or do i need st170 ones aswell?

Thanks, Joe

P.s what make discs and pads?

 

Under 17 inch Imola's

 

st170 discs

st170 calipers or any mk3 mondeo calipers (pads are different tho)

brackets and bolts from ebay Ł15 i think

 

I'm selling Mk3 Mondeo ST220 calipers if your interested..

 

But do 300 and calipers fit under 15s. If they do I'm selling my brembos and going for them.

 

Here's a pic of my 285mm cossie setup:



You'll see there is plenty of room for the disks, the issue you'll have with anything bigger than this is clearance for the caliper. As luke19790_3 said though, you can skim some Mondeo calipers to fit, up to you if it's worth the hassle. I'd just fit the cossie 4 pots if you already plan to fit them.

The 300mm's need a mm or 2 taken off the caliper, you'll see once you get the wheel on or try to get the wheel on, just grind back where it rubs...
