I been trying to read through all this info and I have seen both suggested. Are the Hards on the rear meant to last longer? I want to order tires and so far i got the soft fronts shimizu's and both med and Soft rears in the cart? Do I really want the hards in the rear, I know there is a thread that talks more about this- so I'm off to find it. Any help / advice / links are appreciated by this rookie- Thanks!
For the F104 Pit Shimizu 0571 and 0572. Yes it says "hard" on the package/description, but it is still softer than the "soft" front.
For the F103 Pit Shimizu 0541 and 0542. See above.
For the FGX Pit Shimizu 0561 and 0565. With this series of tires, the rears really are harder than the fronts.
80% of your problems are solved by getting these tires. Full sauce on the rears, start with none at the front and slowly add compound to the width of the front tire to get the desired balance.
As a fellow newbie F1 driver that has progressed quickly, my impressions of the F104 are listed below:
In my experience, tuning the diff so it is just on the verge of slipping from a standstill launch will also help the car be easier to drive.
If upgrading, I recommend the High Traction T-Bar to get even more rear grip under acceleration. Getting even a Tamiya CVA shock and M-Chassis gold spring(and adjusting the length for droop), can make the car feel more "locked" down and easier to correct.
More subtle changes can be made by changing the front spring stiffness, adding the heavy pivot post and/or rear counter-weight and adding/subtracting posts between the upper/lower chassis.
