they are the same as megan coilovers which are all the rage for ae86's in the states but with the manufacturers name put on them. BC is trying to get regognised as a brand now and not just simply a manufacturer.
the reds have been out for awhile (megan's are reds) and have had awesome results with ae86's, evo's, wrx's and the list goes on. the new ones are the golds which are supposed to be better than the reds. the golds are available on ebay through a nz reseller.
i like the design of them which resembles blistein shocks with the monotube design.
there are rebuild kits readily available if they blow and they carry a 1 year rebuild or replacement warrenty. so in theory they should last years if you rebuild them.
i am going to buy some when i get on to doing my suspension.
