Hi Da-Sarge, It is very difficult to get brake performance much better than stock. It is possible to delay the onset of brake fade, but it is because modern cars have “Anti-lock” and Hyundai have “Traction Control”. Also you have rubber isolation in the suspension, with anti-dive geometry and non-adjustable shocks.
To get racing performance brakes, too many non-recommended modifications must be done.
1). Light weight wheels and tires give the most performance in braking. Stock brakes can easilly lock the stock tires. Summer performance tires and light weight forged wheels can give you better braking performance but, ... it will cause havoc with Anti-lock, Traction Control, anti-dive equipped rubber suspension components and cause bottoming the shocks. The rubber suspension pieces will deform and typically cause toe-out condition under braking. This is the opposite of what you want if you are racing and diving into a corner. EST. Costs $3,000+
2). Second item to modify willl be fully adjustable (compression and rebound) shocks. You will need to increase the compression setting which will make your road ride harsh. With these mods, ...the rubber suspension components will yield and cause your tires to toe-out in braking. Fully Adjustable shocks, Multi-rate springs and Adjustable sway bars will set you back $3,500+.
3). Thirdly you will then have to change your suspension components to solid spherical joints to maintain control. You need to know a great suspension tuner. &$5,00+
3). Forth, you will need to (very not recommended) modification, ...get into your computer to disable the Anti-lock, Traction Control and install a tuneable manual brake bias valve.
All these mods will set you back $15K to $30K with the knowledge of a great mechanic, ...like Mike Kojima MOTOIQ or Stephen Popodopolus at Popodopolus Racing.
Must less work and cost effective would be to purchase the Hyundai N-sport with Brimbo Brakes, Turbo-engine, gummy tires, great suspension (tuned by former BMW M director and Lotus) and great transmission.
