LACK shelving unit - Type of bolts, or screws for mounting

[enigmatic]

http://www.ikea.com/gb/en/catalog/products/00045560 i have this to put up into a 12m thick plasterboard, which type of bolts or screws would be best to support the load of about 15kg? id prefer to fix into the brick behind as i wouldnt trust the board to take the load

would these be sufficent for the depth into the cavity to wall?

,but make sure you get the ones with the open end do you can use any screw and not just the ones that come with the fixing.but it also depends on how much weight is going to be put in the shevles??

I've used those anchors before, and wasn't pleased with the results. Obviously you can only use the bolts that come with it which can cause problems but sometimes the anchor doesn't anchor at all and will keep spinning when you try to tighten it leaving a big mess in your wall.
