NISSAN’S R89C was a Group C sports racer. It campaigned in the All Japan Sports Prototype Championship series and LeMans during the 1989 season.
This is a curbside kit, with no engine but it does have the transaxle assembly and downforce venturis molded into the underpan. The result is a two-piece body.
Instructions feature exploded views with callout numbers and letters for parts and colors. However the assembly sequence is fairly vague.

Component areas like the interior and transaxle/wing assembly are more detailed. The instrument panel and wheels also have their own insets showing paint detail.
The interior consists of a tub, seat, shift linkage, two-piece instrument panel and steering wheel. There is not a driver’s harness.
The front axle, radiators, front spoiler and transaxle all mount to the underpan. Take care when mounting the front axle and rear transaxle as this determines if the tires will touch at all four corners.

The rear wing bracing, a multi-piece ladder assembly mounts to the end of the transalxe. Test fit the wing to the bracing to make sure it sits level and parallel to the end of the car’s body.
To ease laying out the paint scheme,  the body was glued together and the seam reinforced with Evergreen plastic. Parts D3 and D4 help form the front air intake tunnels and were glued to the body.

Mold lines, running full length atop the fenders, need to be removed on both sides of the body. The windows and headlight covers fit perfectly with minimal flash cleanup.
Rubber tires fit to well-molded wheels and the rotors have cooling holes, but no calipers. Vinyl bushings are to be trapped between the wheels and rotors. Push-mount the tire assembly in as far as it will go to prevent a clearance issue when mounting the body.
Now for the most challenging (or fun, if you choose) part- paint and decals. More than half the build time was spent here. The white and blue are done with paint, the red with decals. Get ready- there are more than 60 decals.

Where the blue parallels the red, copy the red decals and use the cut-out copies as guidelines for taping-off the blue area. The red decals have a white separation line to help, but the blue still needs to be close.

Decals 35, 41 and 43 are used to create a white background for additional decals, but weren’t opaque enough to hide the blue and red.

Two additional layers of white decal stock were used but were not effective. Testors offers white decal sheets that fixed the problem.

A better alternative though is masking the white before applying the blue, trim the red decal to fit and completely forget the white decals.

Some areas require three layers of separate decals, each sealed with Pledge FloorCare Multi-Surface Finish to protect the prior decal. The decals don’t respond well to

Micro Sol and if using Solvaset, leave it on the problem area for one minute and then wick off.

A hair dryer was used extensively on the red decals to get them to follow the body’s roof and nose contours.
With a great deal of patience and precision this can be made into an attractive and accurate representation of a Nissan R89C.
