First Corally car! This Asuga is tons of fun but it tips over too often during turns in grass. Stock tires and suspension.

Any tips for reducing the rollovers?
 
Traction rolling always an issue when running on grass, if it’s your property get the lawnmower out cut it short lol but If not an option I have my buggy setup pretty low & stiff helps prevent it some but not ideal if gonna be running off road bumpy conditions or jumping but I'm more of a ground basher don’t often bring the ramps out. But I still traction roll plenty & pull of some spectacular cartwheels at times, how my buggy still on its original arms I do not know 😂. Tire choice can also make a big difference. On grass probably better with a pin or spike style tire.

Try adjusting the suspension first don't just start cutting things. Moving the shocks in on the towers will improve resistance to rolling and cornering while reducing traction a little. It'll also make the suspension a little less bouncy. With the stock position the Asuga almost but not quite stands on it's suspension with the shocks moved in on the towers it hangs a little more. You can also try leaving the shocks in the stock position in the rear and moving them in on the front tower and maybe moving the rear lower suspension arm up one hole on the hub block to lower it in the rear slightly.
 
No it doesn’t. What you’re saying doesn’t even make sense. If you want to reduce droop, use the droop screws or shock limiters, don’t change shock angles or roll centers.


The primary problem is way too much edge grip tires for grass, which is a design issue for the tires. They’re great for dirt, but not right for grass
 
Correct, moving the shocks in on the towers doesn't change the droop it causes the chassis to sit a bit lower on the suspension because the shocks have less leverage in the vertical direction and more leverage in the horizontal direction. So they resist rolling more but resist bouncing less.

Many people simply put truggy tires on it for grass, skeeter tires work well. Mojave 6S short course truck tires will fit too.

The horizontal/vertical thing is a complete myth. Watch the video.

Try laying your shocks down a bit and running less preload to allow the car to sit lower. It makes the suspension more progressive.

For a detailed explanation on the subject:

Shock angles

With spike tyres, we used to cut every other spike on the outside edge of the tyre to reduce grip roll. Not sure if this is an option with stock Asuga tyres though! 😅

With the stock out of the box setup the Asuga practically stands on it's suspension which works fine on pavement and hard dirt but on grass I prefer to move the shocks to the inside hole on the tower. But I'm also no longer running the stock tires either.

Well for typical bashing types, it's all about the ground clearance. 🤭

However, when cars are standing on tip toes - they're going to fall over.

It's all down to what people want to do. Here in the UK, we have a lot of grass, so off road racing usually occurs on grass or astro surface. These are high drag, high traction surfaces.

For racing, high amounts of traction are desirable for getting the power down, but lateral grip has to be managed to get a balanced handling car.

I literally used to take a box of 1/10th buggy wheels for meetings outdoors, because you never knew if it was going to rain, or dry up and get dusty.

I had Yellow, Green, Pink (now long out of production - rare even back then U6565H and U6565L) and Blue compound mini pins and mini spikes

Then, if it was wet - full spike in Yellow compound:

These worked very well - too well sometimes. If conditions were wet but the tyres resulted in traction rolling - the cutters came out and it was time to start cutting every other spike. 😅

Dry and worn - Proline Holeshot tyres:

I had great results with these in the summer on the hottest days when the grass was worn out and a groove developed on what is essentially a clay/mud track. The more generous side walls made the car less responsive, but greatly helped the smaller 1/10th scale buggies float over developing ruts. My Cat 3000 especially liked these.

Or when it's mildly moist - in a yellow compound:

Schumacher spiral mini spikes.

In 1/8th, whilst there's a lot of choice when it comes to tyres now, it was much more limited at one time - Turbo Rats in a pink compound for every occasion! 😅

In MT racing, it had to be Proline 40 series bowties on grass:

Simply no other tyre offered the same levels of traction, progressiveness and responsiveness. Downside - use them on hard areas - they would be bald in under 5 minutes. These Integy clones are much harder wearing yet still offer great traction.

90% of a good setup - for an off road car especially - comes from tyres. Get that bit wrong, and the car's handling will be sub-optimal no matter what you do. No amount of chassis tuning, geometry adjustment, shock absorber wizardry etc will mitigate it.

Agree 100%. Unfortunately the Asuga has a weird tire/wheel size, so you have to make do with what’s available.

If you figure that the Asuga is 15% larger than a standard 1/8 buggy then 120mm + 15% is 138mm, a bit larger than the stock 130mm tires and that gives you some more wiggle room. There are more options in 135mm~140mm than at 130mm like the 140x70mm aliexpress Phaltlyne clones. Also basically any tire that fits a Mojave 6S will fit the Asuga.
