I've read every post. Don't re-explain, just clarify a tad for me?
The truck needs more wheel rate, going to 3.5 from 3.4 is an improvment. IMO 4.8 isn't enough, but it's an improvement.

I ran red rears vs. green front this past Sunday and liked the greens still. Bench testing you can feel the difference and the truck feels better on our current layout. It has to do with coil bind and the distance the shock travels.

That's what I thought. Okay, Thanks Cameron.

Thanks. Trying to figure if the MMP and reciever will fit happily. Guess it's time to measure. Thanks for finding them Sal, and the pics for a base idea, Dan!

What shock pistons and oil are you using with the rear yellow springs?

Where do you put the speed control?

I ran 1.3 and 25 (too light), went to 1.2 and 25 (too light) and now I've moved to 35 and 1.2's. Haven't ran it yet so I can't say, my suspession is it's still not going to be enough. I have another set of shocks I'm going to build with 1.1s just in case. I have 37.5 and 1.2's in the front, but I was running 30/1.2's before. Air temps have been in the high 60's at race time around here lately, a month ago it was in the high 40's.

My theory is as we increase the rear wheel rate (to closer match the front wheel rate), we'll likely need shock valving/oil that is a lot closer. A common setup was yellow front/yellow rear (4.8/3.1, or about a third softer) and 32/30. If you crank up the rear spring rate 35-50%, I'd assume that would require a similar increase in damping. That's just a guess on my part, I don't have access to a shock dyno or a seven post machine so I don't have any way to measure/calculate it like I can with spring frequency or wheel rate.

I'm going to try the Spring deal tonight and race tomorrow probably. I don't think there's anymore input needed, but I'll voice my opinion about it. (hoping to drive tomorrow is more like it)


On that note, Does anyone have the page number any of the Center Mounted Setup Pics are on? I just want to ballpark idea my own Modification. Thread search failed me this time.
Mine is post #17669, or page 1178 I guess is better.

Wassup bro, glad to see you gave the sc10 4x4 another shot.......

Whens the next time you plan on going to coyote's, it'd be nice to race another sc10 4x4 and talk about setups etc.......

What do you guys think. Just seems weird that it went away then came back. btw I am running the factory battery tray and stock slipper, but have the brace and mantis center diff coming soon.
Thanks

Mine does the same thing. I haven't noticed if it's more prone to clicking when turning left or right. I did notice my top shaft was bent. I'm putting a new one in along with a new diff. I'll be curious to see if the clicking goes away.

The clicking when turning left on hard throttle is the front diff, i test by holding each front wheel one at a time and stabbing the throttle(be cautious of spinning rear wheels). It should make a bad clicking noise when you hold one wheel and not the other, so it's the diff. I used longer 2.5mmx12mm bolts on the diffs, takes a while to screw em in but the longer bolts along with 1 extra shim under each big diff gear and you're set for a long time. Less leaking too because the diff is assembled tight

EDIT: These are the screws i used, any brand will work, size is important

Is there a chance it may be turning to fast and I need to go up to reduce temps? I'm new to this but I know heat will kill a motor, so I would love to get this worked out. I don't mind going faster but can't go any lower than the 13. Thanks for your help.

I have the RTR (stock motor and ESC). I'm a newbie so I'm certainly not pushing it as hard as someone with a lot of racing experience, but I haven't seen my motor go over 165 degrees.
