i think ej9 has same cylinder as ek4 but i could probably sell you ek4 brake master if it wasnt
if you can wait a while i could also supply rear pipes (so you get pipes, discs, pads and carriers but no calipers for £40 + postage)
if you want ek4 fronts (calipers, carriers, pads and discs) yours for £50
so for £100 youd have everything execpt rear calipers posted
