do the Subaru 4 pots use the same size/thread pitch banjo bolts as the stock WRX calipers? i'm looking pretty hard at a set of these, and need to know if i can run my current stainless lines with them (Goodridge lines).

also, will they accept the same speed bleeders as the stock 2 pots? if not, is there a speed bleeder that is compatible?

 

Yes on the brake lines and no on the speedbleeders. AFAIK they use the 'other' Subaru size(there are 2 sizes)bleeders.
Call Dave at Oaoks, he has both sizes of the bleeders, and can confirm the banjo sizes.
Remember that the calipers have to be mounted so that the bleeders are 'UP'.
