Ferrari 312B
Tamiya No. 12048
Model Type: Injection-molded styrene
Molded Colors: Red, black, white, gray, clear
Scale: 1/12
MSRP: $182.00
Pros: Decals; new photoetched parts; good detail
Cons: Instructions could use integrated updates; tricky exhaust
This modified reissue now includes a photoetched fret of detail parts with brake discs, seat belt hardware, radiator faces and wing end plates.

Beautifully printed decals by Cartograf and a set of diecut self-adhesive seat belts are also new.

Tamiya did not update the instruction booklet to include the photoetched parts; a supplemental instruction outlines just the affected steps.
Part of the rear wing is a stack of the photoetched parts, to make up the thickness that was part of the original plastic end plate. A piece of 1mm plastic rod fit in the holes of the pieces, and helped keep them aligned.  

Two wing endplate styles are offered, depending upon which driver version you select. There are etched grilles for the oil coolers, but the mesh appeared to be too large, so I left it off. The grille for the radiator looks much better.  

I filed two sides of the pin part of the shock that is inserted into the body so it looks more like an arrowhead than a cone. I filed a notch in the lip on the inside of the body to allow for the arrowhead to be inserted, making sure the notch was at 90 degrees to the final position. Then I placed the spring, inserted the pin, and turned it to lock the parts together.

The main engine block is divided into six pieces, and molded detail and fit is excellent. Plumbing the fuel distributor is a bit of a tangled mess. The tubing is too thick, and doesn’t bend well without kinking, but after the engine is installed in the chassis it’s not that visible anyway.  

The individual exhaust pipes are a little tricky to deal with; use glue that will give you some “fiddle time.” Wait to attach them to the engine until near final assembly, so they can be positioned to fit through the rear suspension.

The interior has the seat/tub, a cross-member, shift gate, shifter, dash, and steering wheel. Decals are provided for the instruments and steering wheel hub.  

The functional front and rear suspension is faithful to the 1:1 car. The front wheels steer; there are working shocks and universal joints in the half-shafts.  

The instructions show the addition of a spacer to the brake calipers to allow for the increased thickness of the brake discs with their etched faces. I found it better to use two spacers instead of just one as shown.  

The rubber tires have excellent tread and sidewall detail but look to be a little too wide and too square in profile.
