you didn't mention where the car was twitchy, was it too loose on power and/or off power? also how much steering travel do you have, does it turn in 1meter or closer to 2meters?

i have the s120l OP tubes not the s120lt, but i looked at the 'default' setup on the serpent website and it has some settings that you might want to adjust. (i put my preference in parenthesis)

upper arm insert outside. ( inside for the longer upper arm)
0 toe ( a little toe out like 1 degree total)
track width 198, (a typo, i presume you are in the 171 to 172 range?)
pod droop 1.5mm ( 0.5mm droop with a little sag)
there is not tube damping specified ( 10k to 15k is a good start)
0 caster blocks (is this what you really have? and not the 9degree blocks)
caster shims centered (this may depend on which caster block you have)
no mention of front droop ( near 0)
no mention of side spring preload( near 0)

you might try these changes one at a time: (so you can tell us what mattered)
0) set front droop and side spring preload to 0
1) set steering to 2meter circle and reduce to get around the tightest corner
2) reduce rear droop to 0.5mm
3) longer upper arm
4) more tube damping if car rolling too much in chicanes, less if the rear axle is lifting
5) more caster if it turns in too hard

none of this matters if there is binding in the suspension or some other mechanical problem.

i also noticed, you stated tire size at 42 is that front and rear? you might try a 2mm stagger, leave the front at 42 and add a 44 to 45 rear. does DP mean double purple? you didn't mention if this was a stock motor or mod.

My motor suggested 31,5mm and tyre diameter is 47mm.

Other question: have you got a good setup for hi traction carpet with mod?
Thank you!
with a D3 motor can i can fit from 112 to 129 teeth (pinion+spur)

so a 20/92 is 112 so it would put the motor near rearmost location, and so you would have room to increase pinion size with tire wear, but a larger tire would require a larger spur. i think 96 tooth is popular for mod.

DP- dbl pink

It seems like there is no rear grip, as if it's sliding or tail whipping when I turn in to a corner. I know it's my set up because when I switch to my crc car it's totally different.

shock oil I'm using is 500
side tube is 15000 wt.
black spring on center shocks
.50 front spring
side springs are what ever that came with the kit

I will check on my droop when I get back home, but what it says on the default set up sheet is 3.5 droop setting (maybe I'm wrong) so that's prolly what I have it at. Oh running blinky 17.5.

are you using 2xpink/magenta on both cars?

on turn in, extra droop lets the rear lift more, putting more weight forward. i think the genxl has about 0.5mm drooop built into to it. 1.5mm is a lot and 3.5mm sounds undrivable. i forget now, but i recall having to trim the ball ends to get the droop adjustment in the ballpark.

i have been using 12R5 side springs, silver or blue, and 12R5 .020 front springs.

i had forgotten where it was, but check post 112 of this thread for a good starting point, i have made very few changes, just silver side springs

This maybe a dumb question, but how do you set your suspension insert to wide? Do you have to buy the wide insert?

Remove hinge pin holder and flip it so that the hinge pin is closer to the center of the car. Instant "long upper arm." Remember to adjust camber setting via pivot ball to compensate for longer upper arm.

If you want the wide front, you have to have the offset inserts for the lower arms.

I thought that would make it shorter.

These:

Notice how the holes are off center, you can make the front wider or narrower.
