i have a legacy twin turbo. it is for sale. no interest though. looks like i'll be keeping it. i was thinking of uprating the front calipers to 4pot impreza type can anyone tell me whether the 4pots will bolt straight on or will i have to modify or change the plate at the back of the discs?
i'm also thinking of converting from auto to manual does anyone know if i would need a new ECU to completethe conversion?
