only dumb answers
Here is how i have setup my F103.
Remember tho this is a foam setup or a Pits tire setup for rain.
Front springs Tamiya black,10.000 oil on the kingpins(some use AW grease).
I dremeled about 2MM in totall of the steeringbloks(top and bottum) to have me setup the rideheight a bit(safes on truing the tires).
Front is 5MM rideheight.
Front tires and this differs on track, 40 or 45SH foam or Pits PS-0543 for rain.
Rear i have 25or 30SH foam depending on grip(we got a track that generates a lot of front grip) and Pits PS-0545 for rain.
When having a really grippy track go for 36SH rears)
Centre shock 400 Tamiya oil and red Tamiya spring,Tamiya flex T-bar(the one with the S in it) and rideheight 5.5 to 6MM.
The T-bar is mounted at the front battery holder with the old type like you have but without the rubber O-ring but a spacer ring.
The rear battery holder is the pivot ball type.
This will give you a really soft rear setup and it won't wear out the holes on the T-bar.
I use the normall type front suspension arms but at the centre i cut off some material to get a bit of play with camber settings.
It isn't much but i can help to stop the uneven wear on your front tires.
Diff setup is from the F104 Pro but loose the ballbearing in it and use instead the 1 piece trust bearing(and offcourse ceramic balls).
Remember to put the spring washers like this----> )( and not like it states in the F104Pro manual.
It gives you a super smooth working diff that i didn't have to rebuild the whole season.
I use to run this setup with Tamiya A slicks rear and B up front and did have a well balanced car with normall temps.
When hotter i lost a bit of rear grip(tires getting to soft)
Hope you can use this setup where your driving.
Ps i drive mostly on unprepaired nitro tarmac tracks
PS ps i also use shorty lipo's the get the weight more centred
