CTCC Zhuzhou Finale: Chery Arrizo 8 Wins TCS Class on TTSPORT Brakes

On November 2, 2025, the CTCC (China Touring Car Championship) closed out its season at Zhuzhou International Circuit in Hunan. The Chery Arrizo 8, running a factory Kunpeng 2.0T engine and TTSPORT's TR65 one-piece forged six-piston big brake kit, came out of a rough opening day to take overall runner-up and the TCS class championship.

Three days of racing, changing weather, and a car pushed to its technical limit — that's what it took to get here. The finale was the last round of the CTCC China Cup season, and it came down to a full turnaround between Saturday and Sunday.

Round One Trouble, Round Two Redemption

A championship result rarely comes from a clean weekend. In the first heat, the Arrizo 8 was running at a strong pace, well inside podium contention, when a shifter paddle failure took the car out of contention. It was the kind of mechanical gremlin that ends a race in seconds, no matter how the car is handling.

The team didn't have much time to be disappointed. The crew pulled data off the car that night, tore into the mechanical fault, and rebuilt the setup so the Arrizo 8 could roll out the next morning at full strength.

By Sunday's main race, the car was a different animal. The driver kept his composure through a tricky, rain-affected track, hitting his marks corner after corner. With consistent braking and strong power delivery, the Arrizo 8 clawed back through the field and crossed the line first in class.

It's the kind of finish that sums up a season: a car and a team that can absorb a setback on Saturday and win on Sunday. That comeback drive is what turned into overall runner-up and the TCS class trophy.

Drivers Sun Zheng and Wang Wenbin shared the car across the weekend, and it was that pairing that carried the Arrizo 8 from mechanical trouble to a class title in less than 24 hours.

Chinese Power Meets Chinese Braking

The Arrizo 8 race car pairs a factory Kunpeng 2.0T engine with TTSPORT's TR65 one-piece forged six-piston brake caliper — a combination the team is calling out specifically because both parts are domestically engineered and built to race spec.

The engine side is straightforward: linear power delivery that holds up under sustained heat and load, which matters on a circuit like Zhuzhou where cars are on the throttle hard between braking zones. The braking side is where a lot of races are actually decided. Every time the car sheds speed for a corner, the caliper and pads convert kinetic energy into heat at the rotor face. Do that lap after lap and the system builds heat faster than it can shed it — that's fade, and it shows up as a soft pedal and a car that won't slow down where it used to.

A forged one-piece caliper body resists that heat-driven flex better than a bolted two-piece design, which keeps the pistons square to the rotor and the pedal feel consistent from the first lap to the last. That rigidity is what let the driver trust his braking points late in the race and again on a wet track after the rain — exactly the conditions where a driver needs to know the car will stop the same way every time he asks it to.

The TR65's forged construction is built for exactly this kind of repeated heat cycling — hard on the brakes into Zhuzhou's tighter corners, off again, over and over for the length of a race.

One system handles acceleration, the other handles deceleration — and on Sunday, both did their job well enough to turn a Saturday DNF into a Sunday championship.

The Team Behind the Trophy

No result like this comes from one part of the operation. From the pit box to race control, engineers, technicians, and strategists spent the weekend keeping the car ready — first through an overnight rebuild, then through a race-winning drive. The trophy belongs to that whole group, plus the Chery fans and TTSPORT customers who've backed the program all season.

China Speed: The Chapter Continues

From an earlier setback to standing on top of the podium, this finale was a good stand-in for the whole season — every repair, every strategy call, every braking point mattered. TTSPORT keeps building around the same idea: chase performance, never compromise on safety, and bring what's learned on track back to street cars. That's the same philosophy behind the TR65 kit that helped get the Arrizo 8 to Zhuzhou's finish line first in class.
