Popular community setups

Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.

17-inch grip setup

Front and rear: 17 × 9 inch, ET35 · 255/40 R17

Evo owners document 255/40 tyres with coilovers and increased negative camber. Arch clearance varies by tyre: one installation needed no rolling, but that is not universal.

18-inch road setup

Front and rear: 18 × 8.5 inch, ET31 · 235/40 R18

A documented Advan RS2 installation uses these tyres with Ohlins Road & Track coilovers. Check arch clearance at the intended ride height and confirm the brake-compatible wheel face.

Width and offset guidance

Offset range

Check the exact setup

There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.

Common width limit

Measure before ordering

A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.

These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.

Clearance notes

The Mitsubishi workshop specification is 98 ±10 Nm for wheel nuts. The nominal 98 Nm value is shown above; do not confuse this with hub-nut torque.
The original Enkei wheel listing identifies ET38. One tuning reference gives ET35 for stock wheels, so use the original-wheel specification and check the casting when identifying a used set.
Factory alloy-wheel nuts and replacement wheel seats must match. Confirm Brembo spoke clearance with the wheel supplier.
Japanese RS competition and small-brake wheel packages are not fully verified here and are omitted. Keep all four tyres matched on the four-wheel-drive system.
Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
