The performance of compact segment cars improved dramatically due to the technical innovations of each car manufacturers. Tire grips are increased, and “mechanical grips” are also improved by higher performance suspension systems. These factors increases the compact segment car’s bottom speed, and the input value to the wheel became similar to racing cars from one generation ago. The TE37 15inch size has been on the racing field since it released in 1996. In order to surpass the performance of the TE37, the new TE37 was necessary. Therefore, everything is redesigned. [TE37 SONIC] was made as the new TE37 to match the high performance of compact cars. The strength and rigidity are enforced by creating the spokes wider than before and moving the mounting surface of the spoke end to the rim.
The TE37 SONIC exceeds the TE37 to create the new racing scene.
