Are there brake booster & master upgrades for our cars? I know most of the better braking will be with the pads, rotors, calipers, stainless lines, but I want to further improve my whole system because my stock master is leaking at the seal in between the master and booster. Just wondering if I can upgrade rather than replace. Stock is not really made to handle road course racing.
No. Stock master and booster can handle c5 brakes so...
Money would be better spent on larger caliper and rotor hardware. If anything get some quality pads.
Oh ok thanks guys. ill take note. Should I replace just the seal or or replace 21 year old master?
If the master is not leaking then it's fine. If your brake pedal is hard to push and brakes do not engage then I'd suspect the booster or bad/glazed pads. Before I did my C5 brake conversion the brakes were really bad. Could not lock them up. Figured it was due to the pads. Did the conversion and they felt the same. Replaced booster and it was night/day difference.

Yeah I'm having the same issue even though I just replaced my pads & rotors last week with hawk pads & baer 1 piece slotted rotors and still my pedal is to the floor and can't lock brakes or even get the tires to faze. Braking seems the worst when the brakes are cold. Usually it's supposed to be the other way around. It's been acting like this for the past month but my master has been leaking alittle for the past few months. I've blead the system, topped off fluid, and got steel lines and the only thing left is booster or master?!
If your pedal is going to the floor then there is air in the system or you have a leak. Get a Motive power bleeder and it'll make your life easier. If it were your booster the brakes would be hard to press.
