320mm brake wheel size?
 

I'm really confuzzled. I'm thinking of doing a focus ST brake swap on my c30, now i know all the componants will fit, but i'm courious about the wheels, as internet is giving very conflicting information, basiclaly i want to know if 17 inch wheels will fit over the 320mm dics's calipers. These were fitted to the s40 and v50 AWD T5 variants, now if you check an US site it says the 17inch wheels will fit, but on a few Euro ones they say you need 18 inch ones. I know the The focus ST's have 18 inch wheels standard, and funnily no one in the ford forums knows if 17s fit as they go up wheel sizes now down and assume ford have fitted the minimum size required.

does any one have access to some specs that can confirm what wheels are required.

thanks

My D5 has 18in wheels and 320mm discs & to be honest just looking at the front brakes I would say there is room to go down to 17 inch wheels.

I have just checked the sales bumf I have that states that D5 & T5 have 320mm discs upfront regardless of which spec of trim the car is, so I can gather that most D5 & T5 will be fitted with 17in wheels as only the R-Design SE Sport & it’s predecessor the SE Sport came with 18in wheels standard.

Hope this helps.

I'm assuming that my 2.0d Se Sport doesn't have 320mm discs then? Thats the info on the ST brake conversion as i have 18 inch wheels?

humm, perhaps i'll see if i can chuck a 17 on an ST at work and see if its fits. i will get beiiger wheels at some point but i cant afford the ones i want right now, i do need bigger brakes as the ones fitted ate wholy inadequate., and tyres really need tyres lol.

basically because the c30 etc have the same front suspension as a mk2 focus anything that bolts onto them bolts onto ours, so i needs calipers, discs, pads, braided lines ( might as well it'd be daft not too) and the backing plates. I'm saying ST but volvo use the same caliper/parts on the variants with the 320mm discs, i work for a ford garage so i can get what i need pretty cheaply.

I'm assuming the V50 has the same suspension as the C30 unless they changed it somewhere ?

should be but possibly heavier load springs.

My D5 is currently on 17" wheels with the big brakes.

What the V50 has heavier load springs ?

I would have thought that if any of the suspension was uprated it would be the rear on the V50 to componsate for heavy loads to be caried, I know that this is the case with many estate's over their saloon / hatchback siblings.

As far as I am aware their would only be three suspension set ups for the front for the whole C30, S40, V50 range.

S SE SE-LUX standard set up suspension
Drive Models have a lower more aerodynamic set up
R Design, R-Design SE have a stiffer sports suspension set up.

What are the 320mm brake calipers like on an ST and T5 2/4 pot ect.
