I'm not sure... Cass sent me a new master cylinder. Although better, it's still not great. My car isn't driving yet though. So I'm not really sure. It'd be nice to drive it and rebleed after it's had some heat and drive time on em.
You have 4 wheel disc brakes and a 15/16" master cyl, although it gives you more stopping power it takes more travel to move all the pistons. I think you would be better off with the 1 1/32" master cyl as it will move more fluid and not travel as far. Power booster would help a lot, the ratio is different and you can use a bigger master cyl.
