Thanks.
Yes, the gold is the medium spring. The silvers are soft (super thin wire), then gold is medium (a little thicker wire), and black is the hard (the thickest wire).

By rolling you mean the rear want's to pass the front?
If so see above.
With the F104 it acts a bit like a roll bar.

Thanks Roy,

Sorry that I did not make it clear, rolling I mean the car rolling left and right

Also can I assume that the middle shock govern the weight transfer of front and back?

The reason I ask is that my 104 keep on over steer even i use the soft rear and hard front rubber tires, and been reading this great thread that having a soft T bar helps this problems, but just want to know what is actually going on

Regards

Hey all!

Any good carpet setups for f104 using rubber tires?

My dad will be racing his at the IIC race in Vegas! We don't run rubber normally so just looking for a decent starting point so the car doesn't do donuts.

Thanks!

I wouldn't plan on it doin donuts, more like traction rollin especially after the groove gets sauced up.
When I ran at TQ here in So Cal, had to stiffen it up, grease on the damper plates and upright pins and stiffer T plate tightened up.
Also lowered the ride height a bunch.
Others will probably have a super dialed carpet setup to chime in with but that was my limited experience on rubber with the 104.

Hi,

Is it possible to mount Shimizu rubber tires on Tamiya chrome rims for rubber? RcMart says they fit only on the foam rims.

#1- remove center screw from Tbar, use a shock rebound foam glued to the top of the t bar to maintain ride height

#2 Glue sidewalls of front tires

#3 start with 60,000 wt oil on front kingpins...go up or down from there depending on feel

I would start with the soft tbar, the green one with no cut out. Without the center screw, that's pretty soft. The black stock one may be good as traction comes up- at least it was good with foam. I would still run the red mini spring or red spring from the black set. 30 wt/3 hole. Slam the car as much as possible. Drop the camber plate (no spacers, directly on lower arms) so you can get the exact camber gain you want with shimming. Same with upper arms, you can raise or lower the upper arm with spacers on the kingpins.

If you have time, you can also try an upper arm setup like this:

What are the red couplers from? I'd like to do my suspension like that as well, not so much for adjust ability but for durability as the upper arms bend all the time. Part # would be helpful

Thanks

Someone here has done it with lots of careful trimming of the ribs to make them resemble the foam type rims.
Just easier to get the foam type rims and save the headaches.

*Xpress (#968-104) Metal Upper Arm Joint Set For Xpress Series

Rcmart carries the parts...also use titanium for the camber links, the aluminum parts bend easily.

Yes it is easily done. I find it a little easier and the tires turn out truer then ones mounted on foam rims. Although with practice they would turn out the same. You just need to sand down the outer rib on the wheel. The inner rib then provides good support for the inner bead of the tire.
their procedure also gives you the addeed bonus of naturally providing about 1/2 degree of- camber. Nice for the rear tires where you don't have any camber adj

Hi F1 fans,

I have my new F104W almost ready to maiden, but would like some suggestions on adding ride height. I have Shimizu rubbers , on the kit foam rims , with which I only have 3mm ride height.
I was going to swap the rear axle holders for the tallest one (#1 I think), but I need to get the front up as well. Do I need to shave the steering block and and shim it down to raise the front up ??
Or do I just add preload shims to the front kingpin springs (making for less travel) ???
I will be running outdoors on dusty asphalt + bumps. I have a HW s/less 13t onboard + 2S stick pack lipo.
