I have a setup sheet filled out at home. I'll post it tonight.

Yes, understeer on corner entry and corner exit.

Sealed asphalt parking lot track. Sprayed with a soda/water mixture on race days.

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.
Why so narrow? B/B XB/C with no wheel shims is too narrow. C/C XA/E with 0.5mm wheel shims should be the starting setup for all tracks. You've also got about 1mm too much front droop which also causes push on power

Because that's what came with the kit. And at some point, taking the wheel shims off seemed to help another steering issue so I assumed making it narrower helped. I will get some blocks to widen it up and test this weekend.

In this case, would it be okay to make both changes at once (widen and reduce droop)?

Thanks Craig.

Yep I'd try both changes and tune from there

Question for people: would it help if I post a base set up along with some tuning tips? if so, what 417 version are most people running?

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.

Sorry to be a pain in the ass
So you are saying that it's best to reduce shim size from under the block ???
I do have a 1mm under the. F/f & f/r

Sounds good, I'll swap things around tonight. I have 1XA in 1-piece and separate, which would you recommend?

dizope,
Toe that sucker out too if you want more initial steering. That's probably what you're missing.

Most setup guides say no more than 1 degree in either direction. I would start by going to 0 at each wheel, then .5 and then 1 degree. Good luck.

I'm at .5 per side now and I believe I have tried 1 per side but will try again this weekend.

That would be great Iam still running the 417x and I have a hard time getting rid of traction roll in high grip carpet conditions.
Thanks

I didn't say anything about under the blocks. Your original question is what should you change if you are happy with your setup but you need more mid-exit steering, and I said to increase the angle of the front camber link. You can either remove shims from the bulkhead or add shims on the c-hub

1mm is a lot under the blocks but if your setup works then don't change it

I always run split because it's easier to drive. 1pc can give a bit more rotation/corner speed
