Infiniti Q50 (V37) Upgraded with TTSPORT Classic 7640 Big Brake Kit
Let's be honest. You bought your Infiniti Q50, and one of the first modifications was likely a set of 19-inch or 20-inch wheels to get the stance just right. But now, every time you look at your car, you see the problem: that tiny, ugly, two-piston floating caliper sitting in a sea of empty space. It ruins the aesthetic.
It gets worse when you drive. If you have tuned your 3.0t (VR30DDTT) engine or simply drive aggressively, you know the stock brakes fade to a soft, mushy pedal after just one or two hard stops. They simply cannot keep up with the car's potential.
The solution is an upgrade that fixes both problems simultaneously: the TTSPORT 7640 Six-Piston Big Brake Kit. It is the visual and performance transformation your Q50 deserves.

This isn't just a replacement part; it is a complete front-axle solution engineered for the Q50 platform. It is designed to perfectly fill the barrel of 19-inch wheels, giving your car the aggressive, high-performance look to match its horsepower.

The Tech: Classic Series 7640 Caliper
The heart of this kit is our Classic 7640 caliper. It’s not just for show—it is a serious performance tool designed to handle the weight and speed of a modern sport sedan.
1. Forged & Lightweight
Unlike stock cast iron calipers, the 7640 is forged from aluminum alloy. This process aligns the metal grain structure for incredible strength, allowing us to "skeletonize" the body. This reduces unsprung weight, leading to sharper steering response and better suspension performance.
2. Progressive Piston Layout
The six pistons are arranged in a specific sequence (Small -> Medium -> Large). This progressive layout ensures a smooth, linear pedal feel—perfect for daily driving—while delivering massive clamping force when you dive deep into the brakes.
3. Heat Management
The caliper is built with vented stainless steel pistons. Stainless steel transfers heat much slower than aluminum, preventing brake fluid boil during spirited driving sessions.
Infiniti Q50 Upgrade FAQ
1. How does this compare to the factory "Akebono" Sport Brakes?
While the factory Sport (Akebono) brakes are decent, the TTSPORT 7640 kit offers significant advantages. Our 6-piston design provides better pad pressure distribution than the factory 4-piston setup. Additionally, our 380mm (15.0") 2-piece rotors are lighter and dissipate heat faster than the heavy 1-piece factory sport rotors.
2. Will this fit behind my 19-inch wheels?
Yes, this kit is engineered specifically for 19-inch wheels. However, wheel spoke designs vary (especially with aftermarket wheels). We strongly recommend using our fitment template to check for spoke clearance before ordering.
3. Is this a direct bolt-on installation?
Yes. The kit includes custom steel brackets designed specifically for the Infiniti Q50 knuckle. No cutting or drilling is required. It installs just like a factory component.
