Just replaced the arms with RPMs, rebuilt the shocks with 60 weight, and it bottoms out with a small drop. Does this seem right to you all?

Thanks Kla912000 for the info.I'm not at home to measure them but looking at the specs of the Team Associated RC8B3 shocks it seems that the ID is 19mm-20mm. But don't take my word for it as I'm not 100% sure. Do some more research to be sure.
Did some more research and found an answer for you. The ID of the Team Associated RC8B3 springs is 20mm.View attachment 151049
I’ll do the same and it would be cool if we can compare results.Thanks Kla912000 for the info.
Will order them with my next repair parts order and see how they perform to the stock.
The Typhon 6s shock springs are considerably less stiff than the 3s shocks. You'll bottom out more with Typhon 6s shocks than stock 3s shocks unless you also get stiffer springs. Kraton and Mojave shocks are also a good fit AND they already come with stiffer springs.Instead of having to buy Kraton or Mojo shocks, just get Typhon 6s shocks. They are an almost perfect fit. I have seen somewhere on this forum saying Kraton shocks don't work. Don't quote me on that!
Depends on your priority. Yes my stiffer springs make the car bounce more on bumpy terrain. But I primarily jump. Once you're jumping high enough, softer springs suited for bumpy terrain will chassis slap so hard you can crack a chassis, trash an ESC, and bend motor mounts even when landing on all four wheels.It's good for the car to slap the ground on landings, If you'll try to "fix" it then the suspension will be so stiff that the car will just bounce around on every bump, making it much worse.
I was referring to oil viscosity, as i said, stiffer springs as nothing to do with chassis slap.Depends on your priority. Yes my stiffer springs make the car bounce more on bumpy terrain.

Sorry, I have to disagree. Of course do the springs affect the behavior upon landing.I was referring to oil viscosity, as i said, stiffer springs as nothing to do with chassis slap.
Of course, but you have to understand that the difference between the spring rates are so small it has really negelible effect. You cannot use springs that are so stiff so the car will not sag from it own weight. so you're left with really small range of spring stiffness.Sorry, I have to disagree.

The higher the spring rating (force required per displacement), the bigger the drop needs to be before full compression of the spring.
Imaging you have a spring with a rating like a real car on your RC. You would need to drop your RC from space before it would be able to compress that thing.
Springs have a huge effect. I have videos to prove it. I make videos of my jump sessions primarily to check the chassis slap and bounce and adjust accordingly. A single turn of pre-load on the springs makes a difference. Oil also makes a difference, but not as much as springs. Despite what you may have read, have you thoroughly tested it with hundreds of jumps on video and spring/oil/pinion adjustments? I have.Of course, but you have to understand that the difference between the spring rates are so small it has really negelible effect.

Oil viscosity on the other hand have way more effect on landings.
I know they do, because they also run high speed over bumpy terrain. Plus they have $1200 6s rigs with all the M2C upgrades so their rigs can take the hard chassis slaps. The OP started this thread because he was concerned about bottoming out. Telling him to have sag in his setup is simply the wrong advice. You won't see me suggesting my stiff setup to someone looking to setup their 3s for the track.You Think rcdude81 and rich duperbash rigs have no sag? Watch their videos and see

Sag has no place in a basher prioritized for jumping. Sag is for racing rigs or running fast on bumpy terrain. It's totally different and OPPOSITE from a jumping setup. Many have repeated suspension advice they saw from racers in this forum. But racers have super light rigs, groomed tracks and smooth downside landings. In general, they NEVER thump landings. If they make a mistake and thump a landing, THEY BOUNCE LIKE CRAZY. When you're stunt jumping, you don't have a groomed track with a nice downside landing. Racer suspension advice is NOT applicable to reducing chassis slap and bounce back in a stunt jumper.
Yes, we're getting off point. The thread was started about reducing chassis slap. Stiffer springs reduce chassis slap.
Again, be careful. That's racing rig advice. If you want to reduce chassis slap in a basher, it's really not the right advice. It says larger piston holes, lighter oil, and lighter springs are better for bumpy conditions. That's true for going over bumps fast while staying on the ground. But many misinterpret such advice to think these measures will reduce chassis slap from a jump/drop. All those measures will increase chassis slap from a jump/drop.This seems like a great resource:
