Just picked up an F1R. When running on Med to High grip carpet, my inside rear wheel is picking up causing the car to "Diff" out. The car corners awesome but I can not get back on the power as soon as I would like. Any suggestions to help solve this issue.

Pits 571/572
RH 4.8mm
White/Red Tamiya center spring with Upgrade shock
Black Side springs - AE
Shorty towards the rear
Soft Tamiya Springs up front
Steel Axle
Roll tube, not shock. Tamiya upgraded version
2 Camber

Try heavier oil in the damper tube and stiffer side springs. I currently run Blue AE side springs and 80K in the tube. If the rear is still lifting/loose try a stiffer center spring.

Just moving the battery forward will help a lot with the problem. I run my pack full forward almost everywhere I've run.

Good luck!

Pretty common for the F104 Tamiya ball dif on high grip carpet. The F104 ball diff tends to be too free. Tighten it up or better yet install a F103 ball diff (still works with 104 wheels). F103 style thrust bearing doesnt counter spin so easily, when tightened, thus giving you better launch out of corners

I added the Thrust Bearing, and I am running it as tight as I can get it. I am still "diffing" out. Will continue to work on it.

With my 104v2, I had almost no steering even with the battery forward, with this F1r I am no traction rolling with the battery in the rear. What is the best way to tame the traction roll?

Battery forward glue outsides of front tires

Hello

I'm searching for the "EXOTEK F1R steering crank set [1178]"!
It's no more avaible here in Germany...
Anyone got one or better two for sell?
Please PM.

Regards, Gero

Moved Battery forward to gain in steering and reduce the traction roll. Running 571/572's which I have the front sidewall CA'd. Initial turn in is awesome, but at med to high speed middle off the steering goes away. If I run the non CA'd tires, car rolls over. Any suggestions how to pick up the steerng on the ed high speed corners? Maybe I am just over driving the car. I am about .4 off the really fast cars at my local track.

The diff still diffs out with the thrust bearing. I just got a new F103 setup and will swap out. Hopefully it is just worn spring washers.

Make sure you have the correct diff balls? Stock spur gear 3mm diff balls, Kimbrough spur 1/8 diff balls. I made this same mistake and it drove me crazy.
