what options do i have for my braking as i no alot of ppl have said stick to the pagid discs with ds2500s or mintex 1144 but i have been considering the black diamond drilled and grooved or possibly just drilled with the predator pads and standard pagid pads and discs on rear  but need 2 rear calipers aswell and with a max budget of 450-500 what would the rest of u do with my budget any and all help much appreciated

Get your rear calipers from eBay from this seller. It's our lass's dad who owns the shop, they are genuine items and fast delivery.

If you contact them through eBay they may be able to sort out the discs and pads for you but I can't remember which the stock. They would have to order performance pads and discs in as they arent standard stuff which they mainly deal with.

Large anchor? Parachute? All viable options surely...
