The rapid action of the 2 stage pistons I really liked on any rumble (indoor carpet) or rutted section of the track. smooth surfaces they performed pretty much like the stock pistons which makes sense as the benefit to them is on rough surfaces.

as a side note, I didn't run any additional weight on my sc10 4x4, and I was running a Pro4 4000Kv Tekin motor, before that a Tekin 5.5 SCX 550 2 Pole motor.

Found the setup sheet, for swaybars outdoors loose setup I was running 1.8mm up front, and 1.5mm in the rear.
This stuff really works on a tight indoor track I ran front yellows 35wht shock oil and 20k in the diff. In the rear I ran front blue (huge difference from rear yellow) 32.5 shock oil and 7k diff oil. I also had 4mm on the hub and 6mm on the tower. Now let me just say this was my second race with the truck so I still need some practice driving the truck. I did how ever have the fastest laps of the day by 4 1/10s which is great with the group of drivers we have.

^ I drove his truck. Other than some fine tuning and some practice, it'll be fast against two other guys that are crazy fast with a Tekno and an SCTE.

Stiffening the rear springs and getting the roll center correct seems to be the biggest things.

My new layout and body I jus got done painting. Ready for more racing on Wednesday. Going to do a few more mods... Dye the clicker gears black, cut more of the belt protection off to clean it up, and probably play with the wiring a bit to make it clean.

Yellow rear springs feel pretty darn good at my track. Going to a blue front on the rear seems like a drastic change. Yellow is 3.10 lbs vs the blue 4.30. That's more than a pound!
Even the lightest front spring 3.5 green is a bit stiff.

Better to use the red rear if you think a stiffer spring may perform .

If you test with a stop watch ?
The blue ft on the rear is very stiff , on the 180 they will steal to much roll and the truck will not steer as well .....Laps times slow down ...
Makes the truck looser and can step out unexpected .

Aren't the bronze springs the stiffest rc8 springs you can get. It's funny I run silvers all the way around on my Rc8Be and it's way heavier than a sc10 4x4. I also run silvers all the way around on my sc8be. I just don't get the stiffer springs certain people keep pushing, every time I've tried it turns my cars/trucks into drift kings. Different strokes I guess. I like a little chassis lean and some weight transfer. I usually go with a little softer springs and a little bit heavier oil. Then again im not the fastest driver but last week my fastest lap was 3 tenths slower than the fastest racers lap the night before so I must be doing something right. Weird. I'm still running blue fronts on the front and blue rears on the rear. My advise, tune your suspension for what feels good to you, there are just to many variables to say run this and it will be better. Know what I'm sayin player's. ..

Check the screw that mounts the skid plate to the chassis , should be a 8mm.
If you used a longer 14 mm it will lock the steering ..

Also check if you aline the servo correctly, the servo horn can bump into the chassis if not correct..


If the wheels will not turn ?

Check if the screws mounting the front transmission onto the chassis, if too long can lock transmission .
Also the ck the top screws use to mount the shock tower to the transmission if they are correct lenght.

last , check the transmission screws for the transmission case to the motor plate , if screwed in too much can stick though and bind the front pulley..

by turn do you mean from left to right, or, do you mean rotate?

So as I update my SC10 4x4 I am planning to remove the belt tunnel. Is there any reason to keep it? I am a racer and will be racing on all types of tracks from hard packed clay to soft loamy dirt. Should I be concerned?
