C30 Brake upgrade

[m1nky]

Hi,

I've just submitted a post in the 'brakes & suspension' forum but thought I may get a response here too.

have a Volvo C30 which is the same hub as the Focus ST 225. I'm looking to upgrade the brakes and from what I can find out many calipers will fit, for example the Renault Sport Brembo's. I would however need brackets fabricating for fitment to my car.
Can anyone recommend somebody that either could machine these or has some expert advice. Thanks!

the calipers and discs off c30 d5 or t5 will fit and are 320mm discs and huge calipers.

My car is a D5 and I believe the discs are approximately 300mm. The brakes are OK although I think they could be better. The main reason for the upgrade is since fitting 19" wheels the standard brakes look far to small. A ridiculous reason for upgrading I know!

I know this is an old thread, but m1nky, did you ever installed the Brembo kit on your C30? Any issues with the install?

[m1nky]

I haven't yet though after months of research and weighing up the options I'm just going to bite the bullet and go with a new AP package with 350mm discs.
I've tried to find used options but its been complicated and hard work!!

I`m sure people fit the brakes from an xc90 on these. Otherwise surely focus RS brakes would fit.

AP`s are amazing but very very expensive.

AP's are indeed excellent but costly

Focus ST discs, pads and calipers (not sure how much the differ from the D5's) would be a good upgrade along with braided hoses and nice fresh fluid.

m1nky, are you on c30crew? I know Shark Performance just posted a SBK for the C30 what utilizes a 4-pot Brembo caliper and AP rotors. It's only for the fronts as our rears have a complicated e-brake system. AFAIK, only Ceika and PB Brakes offers complete BBK set for both fronts and rears.

AP Racing offer a big brake kit for the Focus ST that also fits all the smaller T5s that were built on the previous Focus platform.

This kit will not fit into standard 18" wheels on either the ST or the small Volvos so you do have to buy aftermarket wheels with an offset that allows the accommodation of the bigger AP callipers.

I already have aftermarket wheels with an offset of +38. I guess the question now is if the mounting brackets for the Focus ST can be used on the Volvo C30.

[norchi]

They are the same...... if you are anywhere near Chesham, Bucks you can call in and try one of your wheels over my set-up.

Thanks for the offer Don, but I'm actually in Texas

I have the 18" OZ Ultraleggera wheels which should clear pretty much any 6-pot calipers.

I've been told that the XC90 336mm setup will fit but you'll need to drill the stub axle to 14mm for the hangers.
I fitted this kit to my V70 and it's brilliant and you can pick up the calipers, disks and brackets for peanuts.

I know this is an old thread, but I was just wondering if anyone would be able to tell me what modifications would be needed to fit xc90 callipers to a C30 T5. Or Could the brackets from another similar calliper like the s40 awd be used?

[norchi]

The Focus RS has XC90 callipers, but you might have a problem fitting them on your C30 as the RS has the 'revoknuckle' front hubs that might have different calliper location points to the hubs of the C30/ST...might be worth checking though...

Thanks for the info. So do you know if the st225 320mm brakes would bolt straight up to the c30?

I believe the ST doesn't have the Revo knuckle, which would mean XC calipers are a fair bit more likely to fit.

You can also get the 336 disks under 17" wheels if you need to (see above picture)
