GT-1 Motor Sports Type N Wide Tread Spacer exclusively for Nissan cars

It is a wide tread spacer using pure domestic high strength duralumin A2017S.
This type N is a type exclusively for Nissan cars, with a hub center diameter of Φ66 on the vehicle side and a hub diameter of Φ73 on the wheel side.
For example, if a Nissan car is equipped with a non-genuine wheel, the car side hub diameter is Φ66 and the non-genuine wheel hub diameter is Φ73.
In addition, it is possible to install it on vehicles that had a grease cap on the front hub and could not install a spacer with a hub center, as long as it is equipped with an aftermarket wheel (φ73 hub diameter).
Our wide tread spacer increases the mounting accuracy of the wheel by press-fitting the hub bolt, but by installing this type N, the center can be put out, so the mounting accuracy is further improved.
The included special nut is designed so that it does not protrude from the spacer surface, but the vehicle side hub bolt may protrude from the spacer surface. In this case, please note that it cannot be installed if there is no relief on the wheel mounting surface. Also, please note that there are extremely rare wheels with a center hub diameter of Φ72.5.
