So I recently installed an exedy twin with my trans rebuild and started to have issues after 150 miles that may be related to the master cylinder. So I ordered a new oem master and slave from STM, but I also decided to do a little research in the meantime. I was looking at rockauto and they have a clutch master that is manufactured by exedy which is a quality brand (pn#mc520) which is listed to fit our car. Problem is it's only $20 compared to the $120 for the oem which makes me question the quality/compatability with our cars. I wanted to know if anyone had tried this master as $100 is quite a price difference and if it's just as good as oem I would rather have an extra on hand for 20 instead of paying 120 for an extra oem one.
