braking options?

what other options are there for front brake discs/calipers and rear handbrake calipers as sierra seem quite heavy but others like wilwood seem good quality but expensive.
could honda s2000 brakes be used/modified to fit or are they also quite large? thanks

was un sure what would fit with alloy upright and ford hub? was un sure of wheel size i would need to accomodate caliper?
ideally if i broke an s2000 i would like to fit them but i would imagine discs and calipers are large and heavy! it may be better to sell the s2k brake package (not sure what they are worth) and fit wilwoods with a lighter disc

personally i wouldn't bother with the coupe brembo callipers they are huge weigh a tone and are pretty prone to sticking pistons. you will also need a minimum of 16inch wheels with quite a large of offset as they stick out quite far from the discs and hit the wheel spokes oh and you will need 305mm discs 28mm wide which also weigh loads.

how do i know all this? lets just say i have been down that road.

Daniel, what about MNR's R16 replacements.
They are light, and work.

personally i would go with wilwoods all the parts and brackets are off the shelf items.

your looking at £250ish for a wilwood kit from rally design. you can prob make that selling the honda items on the bay.

i would only use the honda brakes if i was using the s2000 front uprights

MX5s, although they are 4 x 100 studs not 114 like the Fords, which are actually 108 (Thank you!). . The cable handbrake works very well too.

ps My god, I can't know everything!

I wouldn't worry about disks, go to your local motor factors and ask to look through the QR catalogue and select the size, offset PCD you want.

108mm PCD makes and models include

Pug/CitroŽn 4 stud
Audi 80 4 stud
Ford 4 stud.........

The disks do not have to match the original size exactly although thickness is a little more important, they have a range:

Saying that, by the time you have messed about the Wilwood option will have seemed cheap!

Wilwood at the front makes for a very good value and competent package.

The rear is more difficult. People have tried:
Sierra calipers. Popular for all obvious reasons, despised for all the obvious reasons (weight, rubbish handbrake, weight). Use with Escort Mk3 front disks if you want to fit under 13inch wheels.

VW Golf mk4 style (also on Audi's) alloy caliper. Similar geometry to Sierra, but a bit lighter.

Rallydesign VW Golf "equivalent". Not clear to me whether this is the same or slightly different. Some listings on here mention this.

Peugoet 205 (and other models ). Nice and light especially when used with Fiesta 1.1 (i.e. early) disks. Also mentioned on here. Sounds like a light package.

BMW Mini



There are also after market options:
Hi-spec, nice design, reasonably price. UK made. Poor customer service.

Wilwood by Rallydesign. Poor handbrake, not cheap for what it is.


The other problem with disks is fitting it all under 13inch wheels. But if you are going 15 then most of these problems go away.


http://www.brakesint.co.uk/ is a good site for investigating disk sizes and dimensions.


There isn't an easily implemented, cheap, light rear braking solution out there. In my view. I have Sierra because I haven't upgraded yet!

I'm using (bought from MNR) Raceleda uprights + R16 willwoods + R888... incredible stopping power.
In both Algarve International Circuit and Estoril GP Circuit I'm braking in 100 - 90 meters mark... very impressive!!! You have to break really hard, so mass goes to front and wheels won't lock.
Balance bar is set 75% to front (well... al this in dry weather, of course...)

Regards,
Joao

Once there on your really not going to notice the weight especially with the rears id leave them with brackets made to fit the job making it simpler and cheaper to look after. For the front i have the wilwood calipers with MNRs vented and drilled discs although i am sure how easy these get upto temp. The pads however i would avoid the smart pads, many seem to opt for the mintex 1144's which il be trying soon.

yes for solid discs, MNR ones are drilled & grooved.

Don't need anything more, they won't get up to temp.

if they don't get up to temp then why have them drilled?

How about sierra drums? Light, cheap and makes you stands out from all the rear-overbraked sevens
