The special specification car 990S is a hot topic ND Roadster, but about 7 years have already passed since its appearance, and it seems that the deterioration of each part is worrisome in the initial model that has been running repeatedly.

When it comes to refreshing the suspension, which is the lifeline of ND, it is common to replace shock absorbers and tires, but I would also like you to pay attention to the "rubber bush of suspension" at the joints in humans.
Bushes are scattered in various places that support suspension arms (more than 30 places in ND!), And are very important parts for suppressing vibration from the road surface and moving the suspension smoothly.

If the bush is cut or cracked hard, even if you replace it with a new suspension or tire, the mounting part will move steadily while driving, causing symptoms such as wobbling of the car body and increased vibration.Especially when cornering, where the load on the car is heavy, the behavior tends to be disturbed, and the handling performance that is characteristic of ND cannot be demonstrated.

If you replace it, the whole car will look crispy!Mass-produced products that are comfortable to ride are safe for many users, but if you prefer a crisp handling that is stiff but has little play, our concept is "more than a sports car, less than a racing car".Suspension bush setIs recommended.By making the rubber 110% to 140% harder, you can polish the agile movement of ND.

It takes a lot of time and effort to install the suspension, such as disassembling the suspension and pressing the bush into the arm. It is difficult to work unless it is a special shop, and the labor cost is high. Great.To all ND enthusiasts who are particular about driving, I would be grateful if you could take this into consideration when refreshing the suspension.
