TLR 22-4 carpet issues

[janisdaubergs]

Hey,

Had 2 races with my brand new 22-4, running it on carpet with minipins yellow and 8.5T SP combo, just converted to shorty and as most of you guys race on Astro/Carpet, would like to get advice:

Main issue for me is that car feels sleepy, and when try to get is cornering fast and tight than my inner front wheel is lifting and I loose steering;

I'm not newbie, race 1/8 for 3 years and I'm fighting for 3rd overall with my 22 2.0, problem is that I can't drive my 22-4 fast enough, as XB4 drivers drive ~ 2 secs faster on 13sec laps.

I tried different setups from petit, I use 500/500 oils, black springs in front and hardest low fr. springs in rear, car as low as it can be, but still seems, that it's not so competitive on carpet, I'm sure I didn't get right setup, so can anybody that had same problem had resolved it?

You need to try one or more of these changes.
Lower the inner rear ball stud
Shorten the rear link
Stiffer rear spring. The low freq springs are all designed for dirt not carpet. Something like a pink or red will be much better.
Rear roll bar may help
1mm limiter inside front shocks may help.
High rear roll centre blocks

Ok what about front sway, oils and ride hight? What about diff stiffness?
Intalled them as in tlr video - rear has full spin and front half spin. Slipper as hard as it can be.

Now shortened rear link, installed shorty as far to front as possible, black buggy spring in front red in rear, 500-500 oils, 1.5 cambers front shocks 1mm shim.
Have stiffest sways in both rear and front and about 19-21 height. Front can't be lower as sping than would be too short.

Wow. Not sure you will need all that. I would take off the roll bars. If the problem persists then start adding a rear roll bar. Start with a soft one and work up. Front roll bar will just reduce your steering feel.

Diffs will be fine like that. It's a fine adjustment that you tweak when you have got the balance of the chassis sorted.

Thanks for all the help!

All of that was added one by one in last event, when I was driving saddles and just couldn't get it right.
About diffs I asked, as guy with kyosho is driving ball diffs so free, that wheels can be spines easy, I just thought maybe mine are to tight, and that's why I can't get tight corners - because they are spinning in very equal speed, as as I thought maybe I can't do it as my wheel spins in more equal speed, than needed.

Have anyone tried to add some weights on front arms, if nothing helps?

Also I'm thinking maybe I got the driving wrong for 4WD, with 2WD all is clear for me - just give throttle when car is on straight and brake before corners and do them with small to none throttle applied as tight as possible, that takes me to 2nd/3rd places. What about 4WD, where you start to apply throttle - in middle of turn?
For now with intellect slim shorty 3500 I get my car at 1676 grams, seems as a good result. Yesterday also moved shorty to as much forward as it can be - till it hits belt cover screw mount.

What about flipped shocks - it it a must mod and what can I get from it?
