Hello everyone, this is going to be somewhat of a compilation of several posts from the old forum in combination with some information I've gathered. Acknowledgements and credit to Scooter1640 and Madskillz for their pioneer mods!
It is no secret that Suzuki skimped on a couple components of the 750 to keep costs down, namely the brakes. The stock two-piston sliding calipers work but it takes a bit of a lever pull to get some more results. For anyone who has ridden a proper supersport, the difference is night and day. Here are a couple ways to spruce up the budget brakes for an improved braking experience.
Stainless Steel Braided Brake Lines
Stainless braided lines will decrease the amount that the lever has to travel to apply the same amount of force on the brakes. This is because normal rubber brake lines expand to a small degree, which partly causes the mushy lever feel. SS lines make the brake lever pull stiffer and are a good place to start. I bought only the front lines because I lock the rear under hard braking easily enough. It's up to how you like your brakes to feel.

Caliper Swap
With the use of a bracket, caliper swaps are very easy. Luckily for us, we are able to use brackets made for SV650s to fit a wide range of Nissin and Tokico four-piston calipers onto our bikes.
Nissin Caliper Brackets Direct bolt-on options: CBR 600 F4 - F4i All Model Years, 2000-2001 CBR 929, 2002-2003 CBR 954, 2003-2004 CBR 600RR, RC-52 2001 SP2 and up. These are all relatively the same caliper- pick your favorite color. (Note- CBR600RR calipers from 2003-2004 are gold, CBR600F4i all years have a nice OEM dark gray.)
Tokico Caliper Brackets Direct bolt-on options: 2001-2003 GSXR 600, 2000-2003 GSXR 750, All model years of SV1000. Again, all relatively the same calipers.
These calipers are readily found on eBay. Depending on the age and condition, you may want to buy new seals and refurbish the calipers to prevent sticking pistons. A new set of all of the seals on two CBR600RR calipers cost me about $50. Your best bet would be to buy as new of a caliper as you can find (F4i calipers will go up to 2006).
Check the second post for a writeup on how to replace the calipers!
Master Cylinder
This is still uncharted territory. Currently with SS lines and CBR calipers, the brake lever still does not provide a huge punch-in-the-gut initial grab like my buddy's ZX-6R, though the brake performance has increased substantially. Stoppies and locking the front are very easy. I'm assuming a master cylinder with a bigger bore will help get the braking to the next level. It should be pretty straight forward- find something that the banjo bolt will thread into that also fits onto the bar, then find a way to remount the mirror or go to a different mirror setup. Something radial would be a plus! Stay tuned.

. When I happened to notice that the calipers on both bikes where the same. So at first I was angry. Why would Suzuki make such a brand new bike and put 10+ year old calipers on the bike!!! Then it hit me, this was a blessing in disguise, so if the caliper and rotor setup on both bikes is essentially the same, then it would figure that aftermarket mods for my older era Suzuki's should also fit the GSXS! So I did my research and came across a thread for a 4 pot conversion for the
