Other things to check for is your left to right balance and a rear axle that is too tight. If one side of the car is heavier than the other it will cause the car to act tweaked. And if your rear axle is too tight then you will have more drag on one side of the diff than the other which will also cause the car to feel tweaked. You need to have a slight bit of play in the rear axle to prevent it from binding.

When was the last time you changed your front springs? They will collapse over time, especially the left one on a counter clockwise track and vice versa. Also, are you gluing the side walls on the front tires? That will calm the car down. Are the tire sizes even left to right? How long is the sauce on for? At least 15 minutes?
What are you setting the ride height at? Sometimes a slightly higher front height can help if your car is not getting traction. Another part that might help you is the 3.5mm offset steering arms. They will help the car track straighter and take away a bit of steering.
Also, make sure your body is not fouling the wires or rear pod in any way. If you have to raise it up, do it.
Here is a setup for a VERY high bite track with A foams:

I will check the body height for clearance and then mess around with the support trays and see if there is an issue there. Heck, I might just strip the entire car and rebuild it again just to see if I missed something. Thanks for the suggestions so far.

Hi,
Some put 70grms weight at the rear diffuser.

Is mounting the servo with the output shaft up (a la robk) considered TCS legal?

Very true! I am realizing that the axle bearings are very fragile. Twice in the past month I have found a 'chattering bearing' on the axle. This was causing the axle to not be as free so it was making the diff uneven left to right causing erratic cornering until the bearing was replaced.

I too go thru bearings like dollar bills at the strip club.
Not sure if that would explain why the car is a bullet for about 4 or 5 minutes at the most.
Happens all the time for me with foams on asphalt.
Gotta figure how to get it better for when the "dope" is used up from the tires.

I have transformed my F104 pro to a F104w.
I think that the only differences between two models (F104 vs F104w) is that the F104w uses the F103 tires and F103 front arms. Rest of the cars are similar.
In my opinion, if there are no rules regarding the width of the models, I would prefer the F104w, my experience is that is more stable entering and exiting curves.

Does anyone know the part number for these bearings?

No...they are the same as the F103 arms and don't have any ride height spacers. At least on my Lotus F104W.

This has worked for me and allowed me to run more ride height for smaller diameter tires (foams) and lower ride heights when running taller rubber tires.
