Tamiya F104 Pro!
#4773

Still having issues with the back end being quite loose and I'm quite sure its the tamiya rubber tires are the issue. The rears are about as hard as the fronts. Even though they are sticky as hell the back end comes around pretty easy. Its like one of you said, I can get about 3 or 4 laps in before the tires pick up track crap and then they glaze over and its sh!t. Have to find some foams, my buddy had foams on his last friday and he drove his car up the rear of my 12 scale!! Other tuning settings are for not until I get some decent tires.

If you want to drive on rubber and you have to use Tamiya then type A slicks for the rear and type B slicks at the front.
If you want to try foams the HBR soft for the rear and HBR medium at the front is a good starting point.
And yes the HBR tires are stil out there on e-bay.
Or if you can get your hands on foams with a shore indication,start with 40 shore at the front and 36 or 30 for the rear.

Do all the traction adding tips for the rear end, T bar, spring, shock oil and damper plate all super lite/free.
Stiff springs up front and raise the front ride height, lower the rear.
Make it push then start to dial in more steering by lowering the front height little at a time.
Only sauce the rears at first.

Then again, maybe just adding fatty 103 rears will get the rear stuck?
With the 103 front end and tires, it will be converted to the new F104W configuration which is not a bad thing either but the F103 is still, arguably (or not), better.

Having both is cool but the 103 is surely the race car.
Our Ultimate F1 series is off and running again and we have classes for Open which is anything goes and Realistic which is current F104 specs with 21.5 motor and rubber tires.
For the Open class it is without a doubt the 103 on foam with 13.5 (or even faster
) motors settin the pace for as long as you can keep a handle on em. Braaaaaaaap
