Lexus ES300 Big Brake Kit Upgrade / TTSPORT Classic 9200
The Lexus ES300 sells on comfort and quiet composure, not raw stopping power — and the stock brakes reflect that. To back up the car's looks with brake performance that can actually keep up, this owner went with a full front-and-rear TTSPORT big brake kit rather than just swapping pads.
Behind the 17-inch factory wheels, TTSPORT installed a TT9200 split forged four-piston caliper on the front axle and a TT7609 split cast four-piston caliper on the rear, both paired with 330x28mm high-carbon heat-treated curved rotors and finished off with TTSPORT stainless steel brake lines.

Why It Works
The forged TT9200 caliper body is one piece, so there's less flex under pedal load than you get from a stock single- or dual-piston floating caliper — that translates to a firmer, more predictable pedal. The curved, slotted rotor face clears debris and gas better than a solid disc, which helps keep pad contact consistent under repeated stops.
- Forged front caliper adds rigidity for a firmer pedal feel
- 330x28mm curved, slotted rotors both axles for better heat and debris management
- Compact TT7609 rear caliper sized to clear the ES300's 17-inch wheels
Adding the rear TT7609 four-piston caliper alongside the front kit rounds out the brake bias front to rear, so the upgrade isn't just about a bigger front rotor — it's a matched system. The forged and cast caliper bodies are also lighter than they look, which helps limit the added unsprung weight at each corner.
