Is there a secret to getting more steering consistency on an F1? I am running a CRC WTF1 FC16. I feel like I fight the car down the back stretch just to keep it straight. I've upgraded my servo to a standard size servo and changed the mounting of it which changed the servo saver orientation from perpendicular to horizontal. It just feels like it wants to drift, like it has a mind of its own. I've checked my alignment. I've set my end points. I'm turning fast laps but feel like I am losing some time simply because I just can't "drive it". I have to fight it.
Running on black carpet, btw.

Shimizu tires. I am running friction pegs in the diff as I was trying to combat riffing out.

The pegs are way stiff when you first run then for the 1-2 minutes. then one heated or warmed up your car stabilizes doesn't it. If so hold one wheel and lightly hit your throttle to warm the diff action. see if this helps you. I haven't run Pit tires in years now. I found I like the CRC premounts and have also been running the Gravity premounts.

It doesn't seem to lessen over a run. I can attempt to do as you say. Maybe I need to try without the pegs, just go back to ball diff, to see if I get the same steering inconsistency. At least then I can rule out the diff or confirm it is the diff pegs.

I'd have to measure my toe out but it is not excessive.

You need pretty good traction to run pegs.
The rear end should not be a spool unless you have a smooth track and crazy grip . You should also be running diff balls and pegs in the spur unless the grip is crazy so you can have some adjustability. You can go from lock to "normal" diff action this way.
I would also start by making sure the football pivot is 100% free. Run 1.5 to 2* toe out as well.

On the diff prep I too am looking for answers on how to prep the pegs since they seem to be more than the diff ball height. Somewhere on this forum I read about someone making a jig to cut the pegs to a specified length so they would work in conjunction with the balls as opposed to replacing them.

i do think warming certain tires might be needed to have enough grip to support pegs or spools
i needed to run a MASSIVE amount of laps w/ CRC pre-mounts to get my car "working" at Snowbirds. same car - different track (360v2) - CRC tires had the same issue, but my freshly mounted gravities did not (after the 1st scary run, all other runs yielded super fast runs).
when doing this be careful... you car might start hopping down the straightaway (this happened to me at 2017 IIC .. )

Edit: Never mind. I was thinking of the Ride tires.

Has anyone tried the Gravity premounts on gray carpet?
I'll be giving my personal car a shakedown run on Wednesday with them, but wanted to hear from some of you guys as well.
