youll need integra hubs to install the calipers, the civic hubs are too small and usually about 1/8" off fom both holes bolting up.
the only way theyd bolt diresctly on is if u had a 94-95 car with abs. but then youd already have an integra braking system
now if u already have the hub, what help do you really need a good mechanic can just tear anything apart and put it back together. its easy. just unbolt the factory hub, using a pickle fork to separate the joints, add the new peices put the nuts and bolts back on and hook up the brake lines, its really that easy.
