ISC Performance

To ensure the IS Convertible delivered a high-performance driving experience—regardless of the position of the top—we started with the same suspension system as the IS sport sedan, then made adjustments where necessary. For instance, we reinforced the chassis' upper-support bracket for the rear shock absorbers and optimized the suspension bushings and the rear-suspension rubber mount. We also fine-tuned the front and rear springs, as well as the shock absorbers, all to provide the optimum balance between ride and handling.
