it was a question asked by some but not answered , i tried googling and found nothing definite , for those interested , the 2001 to 2007 impreza Tegiwa brake stopper fits the the sg9 and therefore probably the sg5 forester and xt , plus it seems to make a big difference similar in feel to braided brake lines , i need to properly test it but initial braking is much firmer , a bit of a fiddle to fit bit for 43£ well worth doing
