Vehicle
Nissan Skyline R34 sedan in silver, on white RAYS forged monoblock wheels. The front axle now carries a four-piston monoblock caliper and a 330 × 28 mm slotted rotor.
Selected setup
| Axle | Caliper | Rotor |
|---|---|---|
| Front | GT40-MONO — 4-piston, forged monoblock | 330 × 28 mm, slotted |
Why a competition caliper fits a 17-inch wheel
GT40-MONO is the lightest caliper TEi builds, at 2.76 kg. That matters inside a small wheel: less unsprung mass, and less of the barrel taken up by hardware. The body is a single forged monoblock rather than two halves bolted together, so it can be made narrow without giving up stiffness.
Four opposed pistons spread 49.47 cm² of clamping area across the pad. Fluid runs through internal passages instead of an external crossover tube, which keeps the line clear of kerbs and debris. Pads come in M2 metallic for the street and R1/R2 track compounds for lapping days, so one caliper covers both without a second purchase.
Fitment
GT40-MONO is offered in 15-, 16- and 17-inch rotor sizes, from 290 × 24 mm to 330 × 28 mm. Clearance depends on spoke profile as much as on diameter, so send us the model, year, trim and wheel specification and we will confirm rotor size and clearance before you order.
