84 cgt brake conversions

[Alan Pritchard]

thinking about a big brake conversion, my options are this....

standard discs and pagid pads for 36 gbp new
cross drilled discs and pagid pads for 75 gbp
g60 corrado calipers, standard rotors and pagid pads for around 110gbp new

is there any other options, ive heard rumours of porsche conversions, whats
a good setup,  i dont think the cross drilled discs will benefit me much, i
think bigger rotors/ more pistons would benefit me more, whats the cheapest
way??  thanks
