September 28, 2025 – Fukushima, Japan — At the thrilling D1 Grand Prix double round (Rd.5 & Rd.6) held at Ebisu Circuit, SHIBATA RACING TEAM driver Koudai Sobagiri delivered an outstanding performance. After claiming the Solo Run Champion and Chase Battle Runner-Up on September 27, he continued his momentum and triumphed on September 28, taking home the overall victory. The competition gathered elite drift drivers from across Japan, with the Ebisu track demanding both precision and endurance. Sobagiri’s consistency and aggressive yet controlled driving won cheers from fans and proved once again the unmatched performance of Rydanz tyres in professional motorsport. The Champion’s Tyres: Rydanz R23 & R31 On the Ebisu circuit, Sobagiri relied on the Rydanz R23 and Rydanz R31, two high-performance racing tyres that became his ultimate winning tools. Rydanz R31 Engineered for drifting, with reinforced outer tread blocks and serrated edges that deliver exceptional lateral grip and stability during extreme cornering. Wide longitudinal grooves paired with auxiliary drainage channels create an efficient 3D drainage system, ensuring confident wet performance. Its high-performance compound and strengthened shoulder design provide durability under intense heat and heavy racing loads. Rydanz R23 Developed for versatile driving needs with a racing compound that unleashes maximum grip and passion on the track. A zigzag groove design and 3D drainage network break through water films for reliable wet traction. Chamfered outer tread blocks “bite” the road during cornering, while continuous central ribs ensure stability under acceleration and braking. Variable pitch tread blocks and wear-resistant compound balance performance handling with extended tyre life. Proven on the Track At Rydanz, we live by our philosophy “ONLY FOR YOUR DRIVES” — from factory innovation to track competition, every tyre is crafted with precision engineering and validated through real racing. Sobagiri’s Ebisu victory is not only a driver’s triumph but also the ultimate proof of Rydanz racing tyres’ championship performance.

On September 13-14, 2025, the third round of the Xiaomi CEC China Endurance Championship (CEC) took place at the picturesque Pingtan Ruyi Lake International Circuit. The event brought together top racers from the CEC, CEC x GIC Pingtan Challenge, and Hong Kong MINI Series for intense competition on the streets of Lando Island. Rydanz Racing participated in the event, equipping their team with the R23 series tyres to tackle the challenging street endurance race. The Pingtan Ruyi Lake International City Circuit spans 2.937 km and features 14 corners, winding along the lake with stunning natural scenery and modern urban structures. As a street circuit, the track has minimal runoff areas and walls close to the road, demanding exceptional skill and courage from drivers. On this extreme track, Rydanz Racing relies on the high-performance R23 tyres to ensure precise handling, acceleration, and braking at every turn. R23 Tyres: Balance of Performance and Endurance The Rydanz R23 series is designed for diverse driving needs, offering specialised compounds for racing, endurance, and daily commuting. The racing compound delivers ultimate grip for confidence in high-speed corners, while the commuting compound balances comfort and reliability for everyday roads. Every journey provides a customised “drive value” experience. On wet surfaces, the R23’s drainage system—with precisely calculated main groove depth and width, along with serrated lateral grooves forming a 3D network—effectively disperses water, maintaining close tyre-to-road contact and reducing hydroplaning risk. The dry grip structure features large outer blocks with chamfered and raised edges, creating a “biting” effect during cornering for enhanced stability. Continuous central ribs ensure even ground contact during straight-line acceleration and braking. R23 tyres are also engineered for wear resistance: variable pitch tread block arrangements distribute pressure evenly, while wear-resistant agents slow shoulder wear without compromising grip, ensuring stable performance over long races. The Pingtan round serves not only as a stage for racing competition but also as a showcase for automotive aftermarket brands. Rydanz Racing aims to leverage the precise performance of R23 tyres to push forward in the championship standings and gain valuable experience toward season-long goals. As the second half of the season begins, Rydanz Racing looks forward to demonstrating both team and tyre capabilities, offering spectators an extraordinary blend of speed and scenic beauty.
