Got a question about the amount of torque twist on the rig.
I am very happy with the way it climbs,-even with rather light knuckle weights,-about 100 grams per side. So the Pneuma chassis do work well

I did a few one-handed driving video clips today,-climbing some quite steep lines.
My computer skill sucks,-and I see now that the phone should not have been held that way,-but here goes:

Have you tried the upper links on the outside of the chassis?

When you say torque twist are you meaning you lift the right front tire or the chassis is rolling back on the left rear shock?

I know its the same thing basically but for me I look at it two ways. If Im not lifting the tire then I may add a little preload to the left rear shock.

If Im lifting the tire then I try spacing my uppers out a little more at the chassis.

Mine does roll the chassis but i havent seen it lift any tires or loose any front traction when it does. Hope that makes sense.

So sorry,-I messed up my grammar here

What I mean is that I got a PM about how I find the amount of torque twist on the rig.
There is almost zero torque twist,-the rig drives very well
And the videos were an attempt to show how nice it does climbing

Yes,-there is a tiny bit of body roll,-but I do not think it is harming the performance

Sorry again

Hello! I have just started buildind a pneuma too. Do you get any tyre rub on your front shocks when you turn at full compression? I have been trying to fix it with wider hubs but cant get it to clear. Im using voodoo pins at stock width, but starting to think narrowing the tyres might be my only option.

Hello. My tires are just touching the springs on the shocks at full compression. But it is not a problem I think. I am running Shift hubs with CI Bolt wheels.

I had to much steering with aftermarket knuckles, stock knuckles solved the problem 👍

Second comp with the rig this Saturday,-and I really messed up the driving.
Ended up at 6. place out of 8 drivers
Car ran very well,-but this time I noticed that the sidehilling is slightly better with my old car,-but everything is give and take,-so this rig does better in other places
Just have to get used to the rig..............and finish the course in time

What foams you using?

I can see a little sag i the sidewall that looks good ..... curious how they feel on a sporty. Im still rocking lugs on mine but debating switching over, interested in what you feel with them on it.
