In this one I’m getting into brake bias and a serious big brake setup for the MK4 Supra—PHR brake bias and the massive AIG big brakes. When you start leaning on these cars harder (more power, more speed, more grip), the stock-style braking balance and hardware can turn into the weak link fast. I’m walking through what I’m running, why I’m changing it, and what I’m looking for in terms of balance, pedal feel, and confidence when you’re actually driving the car like it’s meant to be driven. The big takeaway is that “bigger brakes” isn’t just a flex—there’s a real goal here: consistent braking, better heat management, and getting the front-to-rear balance where it needs to be so the car stays stable. I’m also keeping it real about fitment and planning, because on MK4s everything is connected—wheels, caliper clearance, lines, and how the chassis behaves under braking. If you’re building a street car that sees pulls, canyon runs, or track days, this is the kind of upgrade that makes the whole car feel more sorted.
