Default softer rear suspension = more traction 2wd

Pertaining to MM configuration. My track folks recommended me to soft up the rear suspension, such as larger pistons holes; lighter shock oil and basically try to softern up the rear end? Does it make sense to you? Thanks

Yes. Since the suspension is softer more weight transfers to the rear increasing traction.

Yes and more roll. I would go with 30w the 27w is to soft on high traction with MM3 or MM4.

Are you running Buggy or 2wd SC ?

Losi 22 1.0 MM. I even drill the holes bigger LOL. I spun out a lot during corner, kind of close to off power hair pin turn.... I also tone down the steering servo EPA and speed.

Generally, a softer rear suspension will give you more grip. But make it super soft and you'll just roll too much left to right and lose traction. This is usually more evident in SC where they have a large body throw the weight around. You'll see the body roll a lot and then start to spin out because there's no support.

Look at the car when you are spinning out. Is it when you brake or first let off the throttle? Or are you driving through the corner and you simply lose traction? The former is probably shocks, and the latter is probably camber links.

If it's when you first go off power you may be transferring too much weight to the front, and too quickly. You could try running a stiffer front if you think it's because you have too much steering. You may also take some droop out of the rear which won't allow you to transfer as much weight forward, it lets you drive more aggressive into a corner, and less aggressive out.

Less anti squat usually helps with this too in my experience. The car will want to sit more on the rear giving more traction. More anti squat will make the car sit more flat, even under hard acceleration. This will give more on power steering and generally makes it feel like the car puts the weight on the front much quicker under braking or just without power applied. I'd go to 1 degree unless you're running a high bite track, and just leave it there.

What kind of shock setup are you running? I'm pretty sure that's where your problems are.

Great lesson, glad i asked. BTW, "Less anti squat" mean more shims or less shims in front of the transmission? Thx again.

On the 22 it'll be a thinner shim. They're marked with "slots" cut into the front. Each slot is 1 degree and each half slot is half a degree.

What oil and piston setup are you running?
