418 mounts further in on the arm which makes the sway bar softer. I've been running the atomic sway bar mounts for a while which are similar to what Joey has done and I can't tell the difference from kit

I'm pretty sure they are 1mm taller than the 417 and 417x bulkheads but others will be along to confirm or deny this.

If you was very happy with your setup but just wanted a bit more mid corner / exit what would you change

Depends on the rest of your setup, but arm sweep or lowering the front camber link would be the most obvious changes

Ok I'm going to try the camber link by removing 0.5 mm shim first
Thanks Craig

Hello Craig, could you please elaborate on why lowing the camber links would give the desired results?
I'm guessing its not due to a higher front roll center but rather a different camber gain rate?

Thanks, just trying to learn from your experience.

Increasing the camber link angle (at either end) increases camber gain which provides more traction grip as the car rolls. It's most noticeable from mid corner to exit when the car is rolling the most.

I think the effect of the roll centre change is negligible when we're talking about 0.5mm-1mm difference on the camber link. If I want to change RC I always use shims under the suspension blocks.

Perfect, thanks for replying Craig. The additional camber gain was what I thought would provide the desired results mid corner/exit.

And yes I agree the lower shim affects roll center much much more than angling the upper link the same amount.

Put shims in or take out
I currently have 1 mm under mine
Remember I need more mid to exit
Cheers dude

How can I get my car to have more initial steering, if that is the proper description? My car pushes on corner entry when on power. And it pushes on corner exit when on power as well.

417v5
Sorex 32
TRF dampers with 32.5
HPI silver springs
5.5 ride height
4.5 droop measured with under the arm
.5 under suspension blocks
b/split b (front)
xb/c rear (2.5 rear toe in)
.5 front toe in per side
roughly 25 degrees of steering throw
Tamiya aluminum servo saver horn using kit springs (link)
shocks are in hole 4
-1.5 front camber
-2.0 rear camber
no wheel spacers
stock sway bars
3k diff oil
front spool
3mm shim under inside front camber link
All other settings per the manual

Airtronics MT-4 with 92524
Tekin 17.5 Gen2 blinky
Tekin RS Gen2

Things I've tried with no real success:
- changed Savox 1251 to 1258
- took sway bars off
- turned the steering expo all the way up
- v5 shocks with Tamiya springs (front 32.5/white) (rear 25/white/yellow)
- stood front shocks up to hole 6
- removed 4 screws (inside) from the top deck
- drag brake between 0 and 30%

A friend has a v5 that has incredible steering with a mostly stock setup (no sway bars) but for the life of me, I can't get mine to turn like his does. I even put his RX in and tried it with his TX (different brand).

The strange thing is I rebuilt the car and went to Tamiya in LA 2 weeks ago for the Speedtech race and the car ran awesome. Ran the next week at home on our sealed parking lot track and it was back to usual; push monster.

Could you fill out a setup sheet? They are available on petit rc.
Do you mean corner entry understeer? Also,is this on carpet or asphalt?
