Well, getting a few comments below that this is "All of this is completely wrong." But most of it matches what I found on my own. Or I didn't properly use the tool - It was a deep dive and took over 45 minutes, but then again, I'm not an expert like those commenting below.

It's hard to imagine that is it all wrong...


? Introduction

This guide compares popular aftermarket brake pads for the 2020 Toyota GR Supra (A90 Premium) to the OEM factory pads, specifically for stock calipers and rotors.


It’s designed to help Supra owners choose the right pads for mixed street driving with occasional track use.


It covers:


  • ✅ Stopping Power
  • ✅ Heat/Fade Resistance
  • ✅ Street Comfort (Noise/Dust)
  • ✅ Longevity & Rotor Wear
  • ✅ Value for Money

? Pads Compared

  • OEM Supra (Stock)
  • CSG Spec CP
  • Endless MX72
  • Project Mu Club Racer RC09
  • EBC RP-X
  • Carbotech XP8

CSG Spec CP⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ (quiet, low dust)⭐⭐⭐⭐ (pad + rotor friendly)⭐⭐⭐⭐ (premium but saves hassle)

Project Mu RC09⭐⭐⭐⭐⭐ (when hot)⭐⭐⭐⭐⭐ (track-only)⭐⭐ (noisy, dusty, cold bite poor)⭐⭐ (high wear on street)⭐⭐⭐ (cheap but needs swaps)
EBC RP-X⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ (noisy/dusty)⭐⭐ (rotor wear higher)⭐⭐⭐⭐ (great track value)
Carbotech XP8⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ (squeal/dust)⭐⭐⭐⭐ (pad softer, rotor friendly)⭐⭐⭐⭐ (strong dual-use value)


? Detailed Comparison
✅ 1. Stopping Power

  • OEM: Good for street. Moderate friction. Fades when pushed hard.
  • CSG Spec CP: Higher bite, progressive, confident even cold. Better than OEM.
  • Endless MX72: Strong, linear, better than OEM cold/hot. Excellent street feel.
  • Project Mu RC09: Extremely high bite hot, needs heat. Cold = weak. Best on track.
  • EBC RP-X: High friction even cold. Very aggressive. Outstanding on street & track.
  • Carbotech XP8: Big upgrade. High friction, progressive. Great once warm.

✅ 2. Heat / Fade Resistance

  • OEM: Fades quickly on track.
  • CSG Spec CP: Track-ready fade resistance. No fade in typical HPDE.
  • Endless MX72: Excellent for occasional track. Handles multiple hot laps.
  • Project Mu RC09: Race-grade. Zero fade even extreme. Best here.
  • EBC RP-X: No fade even 20–30 min sessions. Outstanding.
  • Carbotech XP8: Very strong fade resistance. No fade in typical track use.

✅ 3. Street Comfort (Noise/Dust/Cold)

  • OEM: Very quiet. Low dust. Great cold bite.
  • CSG Spec CP: Nearly OEM-like. Minimal squeal/dust. Street-friendly.
  • Endless MX72: Quiet, slight increase in dust (~1.5× OEM). Excellent cold bite.
  • Project Mu RC09: Noisy. Dusty. Cold bite poor. Not recommended for daily.
  • EBC RP-X: Squeal/dust on street. Strong cold bite. Track bias but streetable.
  • Carbotech XP8: Squeals. Heavy dust. Cold bite OK. Noisy but effective.

✅ 4. Longevity & Rotor Wear

  • OEM: Long pad life on street. Fails quickly on track. Gentle on rotors.
  • CSG Spec CP: Long pad life. Rotor-friendly. Better than OEM for track.
  • Endless MX72: Long life. Very rotor-friendly. Top-tier here.
  • Project Mu RC09: High wear if street driven. Rotor abrasive if cold. Race pad trade-off.
  • EBC RP-X: Decent pad life on track. Accelerates rotor wear. Monitor rotors.
  • Carbotech XP8: Softer pad wears faster, but very gentle on rotors.

✅ 5. Value for Money

  • OEM: Cheap to buy. Bad for track. Fade = risk.
  • CSG Spec CP: Premium cost. Saves on swaps/rotors. Excellent if budget allows.
  • Endless MX72: Premium price. Hassle-free for street/track. Excellent overall.
  • Project Mu RC09: Cheap per set. Needs separate street pads. High performance per $ for track.
  • EBC RP-X: Mid-priced. Strong track performance. Higher rotor costs. Great for track-focused users.
  • Carbotech XP8: Mid-priced. Saves rotors. No swap needed if you can tolerate noise. High value.

? Recommendations

✔ Best All-Round (Street + Track):


  • CSG Spec CP
  • Endless MX72

Great performance + OEM-like comfort.
✔ Budget-Friendly Track-Focused:


  • Carbotech XP8
  • EBC RP-X

Big bite, no pad swaps. Accept noise/dust.
✔ Serious Track Weapon:


  • Project Mu RC09

Swap for track days. Unbeatable fade resistance.
? Notes for SupraMKV Readers

✅ Stock calipers & rotors tested.
✅ All pads require proper bedding for best performance.
✅ Brake fluid upgrade recommended for track use.
✅ Price ranges vary ($400–$900/set), always check vendors for latest deals.
✅ This guide is not sponsored – just a Supra owner helping others choose the right pads!

No this is exactly what will happen. Some idiot doesn't know how to use AI properly, and equips it with munitions
Please. I for one have rewatched Terminator enough to know how to handle the end.

Now gotta ask it which one it wants, and which one is more likely!
Ouuuuu… lemme guess. If AI becomes autonomous & self thinking, eventually smarter than us... I’m sure it will see us as worth keeping. As pets to build grunts for it ? Until we’re fully assassinated ?What could possibly go wrong?
