As above you could use GREENSTUFF, but may not want to!!
The current greenstuff is V7, and is crap IMO, V4 was ace, depends how you like your brakes as the cossie will easily overheat/fade greenstuff, unless a very normal spped driver.
I have greenstuff on me other halfs astra 1.4(auto)mk3 and they oiver heat all the time as they just get too hot.
On my cossie I have Yellowstuff, which works from cold perfectly, as does Redstuff Ceramic, and these would be much more suited to "spirited" driving, but still perfectly useable on a cold winters day in the snow.
I use el cheapo discs and change them every year as mine are warped by then, which ever make I use.
