Good but I have the two-stage pistons. Stock I like 32.5/27.5.
I know I know stay AE but the 2-stage pistons really helped on my bumpy track.

Not sure bout the piston , but the rear spring seems awfully stiff .
Do you still have good grip & steering ?

I actually still push a little, but it jumps and accelerates amazing. I did some math and found a couple balanced spring combos:
Yellow outside/ FBlue inside
Blue outside/ FWhite inside
White outside/ FGreen inside (way to soft but you get the idea)

I feel a balanced spring makes the car overall just better.

It should take away steering in the front and calm it down. You are also running the short camber link in the front right? That servo is not quite as fast as mine, but still plenty fast, might wanna try to slow it down. It made a massive difference for me.

Never heard of balancing the springs....:confused:
Do know what a stiffer rear spring will do though .

If I use that combo my ride would have mass wheel spin & a lot less steering on the corner.


Mostly because the chassis would not roll enough in the corner...

yeah, same my rear is loose. But keep in mind, when you take away steering it makes the rear more easily controlled. I see a lot of people complaining about most of the SC trucks in sweepers. SC's IMO dont like high speed sweepers. I dont have to deal with high speed sweepers, just a lot of 180 and 90 deg turns. My plans this week are to try.

Short Front links
5mm camber washers
yellow spring
middle top and outside bottom shock
option rack with rear position hole.
32.5 AE oil 7k diff
2.2 sway

rear inside tower and middle hub for the camber link with zero washers
middle top and inside bottom on the shocks.
27.5 AE oil
5k rear diff oil.
extorek clutch with VTS slipper
Battery stick middle
2.0 sway
yellow rear spring but will also try blue fronts
hub back ( I will play with hubs middle and hubs front also)


I will also be playing with front tires. I think a less grippy tire up front might be of help.

yes, I want this, a lot less steering.

I actually tested my truck for balanced springs and those are not even close to what I got. I dumped my shock oil and dropped the truck from about 3" and video taped it, found combos that were spot on.

Front yellow-Fgreen in rear
Front Blue-Rear Red

Truck jumps level and does not chassis slap on anything. Before I did it I was having issues with the front end bouncing, rear was too soft switching springs helped. I dont think it is the end all be all though, I am going to experiment with a softer rear spring maybe Red with yellow fronts see how that does.

one thing I was not really messing with too much and I might start is the tensioners. If they are too tight it causes too much drag when you let off. If it is too loose the belt skips. I probably need to find the sweat spot.

short camber link? im running whatever they gave me in the kit.. by slowing down the servo? on the return or overall speed? i have the mt4 airtronics transmitter.. i was messing with the dual rate last night but couldnt find a controllable feel. or what feels comfortable for my driving style..

+1 on that... if too tight it seems like theres something binding.. seems like my tensioners are right in the middle

short link = outside on the tower lol. As in the shortest camber positions. I would slow the over all. Slowing one way and not the other seems like it would be goofy. The MT4 has a steering speed adjustment i think. DR is what I use because I dont have a servo speed setting. Try playing with the servo speed settings. I have my DR at 60% . Once I get my expo fixed, I might play with that to reduce steering around center also.

ooppps lol sorry bro! i will try that for sure.. probably try in the rear first then the front
