Larger rear brake disks

Just wondering how I can increase the size of my rear disks for under £150 using stock callipers

If anyone has any brackets or a kit or can point me in the right direction I would appreciate it

some used hispec or godspeed kits or DIY 278mm discs & brackets.
have look at thread below ...

for the price you have quoted indy best bet is to find someone with brackets find someone who will copy a set or a few sets then source a 280-300 x 10 disc to use and offer a group buy. is it looks or stopping power your looking for ?

Thanks johnny just looks at the mo

fabrication can be expensive but once one is made say five sets is just a fraction of the price. Trouble is most places need point to point measurements to copy a set
