I can lock up my brakes also and my car now stops beautifully, so my setup is now working better than ever. I had that same problem described by the original poster with my previous brake system. Had 13" discs with Baer 4-piston calipers up front with 1-piston 13" setup in the back and could never get enough braking power no matter which MC I tried. When I upgraded the fronts to the 14" 6-piston Wilwood setup with BP-10 pads, it was a huge improvement. The BP-10 pads are grippy when they get warmed up, and that's a big contributing factor. My first response was geared towards the actual pedal feeling slightly spongy. I agree with everything Ron wrote, which is why I like the manual setup and the extra control, but I also feel a little 'sponginess' in mine, and I know there's no air in the system and I'm using stainless lines(flex and hard) all around. I read a post somewhere, I think it was a Wilwood rep or someone extremely familiar with Wilwood MC's and manual setups, that stated that you should expect a little more sponginess in a manual setup as you decrease bore size. Part of that 'sponginess' you're perceiving is just extra pedal travel which is expected(and desired by people who want that extra modulation). For me, the feel is not a problem, I was just trying to help the original poster with 'feel' expectations on his setup. (that he could have everything matched up perfectly, high grip pads, no air in the system, and might still have a slight 'spongy' feel). Now, if he needs more actual breaking power beyond just the spongy feel, then Ron's write-up is perfect for resolving that. I'd start with upgrading the pads first. And get some extra rags to wipe the extra brake dust off.
