Which big brakes for GBS zero
Hi All,
I currently have standard ford sierra 240mm front disks and calipers up front in my GBS zero and i want to upgrade them to Willwood or HiSpec
My car is running 15" alloys with around 180hp now with a view to go to around 200-240 over the winter with an engine swap and i want to take
this down time to address the front brakes.
There are many kits of various sizes i can see on the internet and it has me wondering which will be the most efficient, im also wondering if someone
can help out with the ease of getting replacement discs for in the future. Im worried that if i go for some kits with odd size discs that if they
discontinue the range i will be stuck. I see one of the HiSpec kits on burton power use 260mm 24mm vented discs and im wondering if that would mean i
could use over the counter oem/aftermarket sierra discs from any motor factors if i needed to get replacements rather than having to buy direct from
HiSpec.
I did contact burton power asking about how future proof the rangers where and if any of the setups shared standard sized discs that are manufactured
by a number of companies instead of just the caliper makers but they could not or would not answer the question.
Thanks in advance
Andy

Most of the conversion use a standard disk and pads from a normal production car it just a case of working out what car

standard questions first:
whats wrong with the brakes you've got now ?
do you feel you want more power, less weight, better bite/feel or just better looking brakes ?
followed by: which brake pads and master cylinder(s) are you using just now ?
(as these will have a massive impact on the bite and feel of the brakes)
if you want easily available spare then you'd best stick to OE spec stuff
not that the 260mm discs should be an issue - even if the kits don't use the stock disc all it sould take is the radial mount calipers and a
custom mounting bracket to make the OE 260mm discs work instead 
the bigger sierra caliper that matches the 260mm discs are a cheap but heavy option (bigger disc and a 60mm piston instead of 54mm)
Dax used to offer an upgrade that took your current 240mm calipers and relocated them over cossie 4x4 discs (278x24mm) - I think someone on here was
talking about changing a set of these for 4 pots (a very cost effective upgrade)

Stick with the standard OE stuff. Remember, these were designed to stop a car twice the weight of your application now, if not 3 times fully laden.
Other aspect to consider, if you upgrade the brakes, you may find yourself worse off as you can't get the brake temps up. I've just
switched to OE 1.8 MX5 discs on my Zero (slightly bigger than the 1.6) and they are far too easy to lock up.
If you can lock up easily then you need to look at the tyres you're using too.
