Following the soft top car (ND5RC) on sale, a sports damper for the Roadster RF (NDERC) will be released soon.
This product is premised on the combination with mass production springs.In addition, it is necessary to check the performance when combined with the low-down spring, so it is a part with many restrictions and consideration items unexpectedly.

For tuning dampers, it is common to increase the damping force at the same rate before and after mass production to increase the sportiness.
On the other hand, sports dampers are not reset based on mass production.Our ride taste recipeIt will be redesigned with a "damping ratio of 70%, 50%, 30%", and the ride quality will be adjusted by "whether to sprinkle salt" or "whether to sprinkle soy sauce" in the driver's sensitivity evaluation.In other words, since the specifications are decided without being aware of the specifications of the mass production damper, the damping force may be lower than that of mass production in some cases.

For reference, the final specifications of the sports damper and the damping force comparison diagram of the mass-produced damper are pasted.It can be read that the front is high and the rear is low for mass production.By the way, the graph is a plot of the damping force for each piston speed of 0.05 m / s for easy comparison, and is actually a smooth curve.

There is no "correct answer" for suspension tuning, and there are few opportunities to test drive and taste it, so basically, you should select each tuner's way of thinking, aim, and index as a hint.
With our unique recipe, we create a "common ride for Auto Exe" even for sports cars, SUVs, and compact cars.You will surely be able to experience a common taste that transcends the boundaries of vehicle types, such as a gentle roll feeling and how the shock is transmitted when climbing over steps such as manholes.

Designed exclusively for the Roadster RF, it is now in mass production!Scheduled to be released in mid-May after the Golden Week holidays.Please look forward to it.
