BMW M4 GT3 EVO in iRacing

Honestly, the M4 GT3 EVO might be the easiest GT3 to jump into on the service. I bought it a couple of seasons back for $11.95 and it slotted straight into my IMSA and GT Sprint rotation. BMW’s S58 twin-turbo straight-six has this meaty mid-range that pulls you out of corners, and the front-engine weight distribution gives you confidence the Porsche and Lambo lot simply do not get. Spa and Road America are where it clicks best for me. Technical circuits work too, but you’ll be fiddling with the setup more to get rotation through the tight stuff.

For a broader look at getting started with setups in iRacing, see our iRacing setup guide.

How the BMW M4 GT3 EVO Drives

Stability. That’s the first thing. Front-engine layout stacks the weight over the front axle, so the car hooks into corners and stays there. None of that rear-engine pendulum nonsense you get with the 992. You can brake later, carry more speed in, and the M4 just absorbs it. Trail-braking is how you drive this car. Drag the pedal deep into the apex and the back end swings round for you. Release the brake too early and the front washes wide. You learn that one fast.

Power delivery from the turbo six is smooth, no sudden spike catching you off-guard on exit. Traction out of hairpins is decent, though a Porsche with 600kg parked over the rear axle will still beat you there. What the BMW does brilliantly is mid-corner communication. You feel the grip through the front tyres, make corrections on the fly, and it doesn’t throw a tantrum about it.

Sausage kerbs are the weak spot. The M4 proper hates them. Spa’s Bus Stop chicane and the Suzuka hairpin entry will bite you if you ride the kerbs too hard. Stay tidy over the bumpy bits and the car is rapid everywhere else. TC and ABS live in the black box. Brake in a straight line, trail into the corner, and this thing will bang out consistent lap after consistent lap.

Setup Observations

Stock setup? Not terrible, actually. Better than the McLaren or Merc out of the box. But there’s a solid second hiding in the setup screen if you know where to look. Tyres first. 26 to 27 psi cold, targeting 27.5 to 28.5 psi once they’re up to temperature. Run them hotter than that and the rear goes greasy around lap 8. Colder and the front feels dead.

ARBs control your balance more than anything else on this car. The M4 understeers a bit from the factory, which keeps you safe but slow in tight corners. Click the front ARB stiffer one notch, do three laps, assess. If the back steps out on power, soften the rear bar instead of undoing your front change.

Brake bias sits at 52 to 54 percent front for most tracks I’ve raced. BMW gave this thing progressive brakes with solid ABS calibration, so you can really lean on them. Position 4 on ABS works for me at most circuits. Go lower for more pedal feel, but you’ll lock the rears more easily when you’re trail-braking hard.

Aero. Dead simple. Pull rear wing out for Monza and Spa, add a click or two back for Barcelona and Bathurst. Tiny adjustments shift the balance more than you’d think. TC at position 6 handles most tracks. Position 5 on high-grip days, 7 or 8 if it’s wet. The turbo motor takes to TC changes smoothly, none of that harsh on/off you get with naturally aspirated GT3s.
