I prefer the F104 diff over the f103 actually. F104 diff is much smoother. F103 is easier to adjust but uses the rim as part of the diff so just not nearly as smooth and free as the F104 diff.

So,
F1Ultra
F103 rear pod
F104 ball dif
F103 tires
Shimizu (103) soft front, hard rear tires
= for the win!

Soft fronts and hard rears? Am I reading that right?

In the realm of F1 tires soft fronts are always harder then hard rears, so yes, it's the hot combo

The hard rears are not actually 'hard'. I think it's a mistranslation- Shimizu meant to say 'hot' I'm sure.

I need the turnbuckles and ball cups to complete the build. Does anyone have the correct part number for the blue tamiya turnbuckles and the appropriate ball cups?

Default springs

Setting one up for rubber.. are the side springs ok for rubber or more foam? Also what brand are the side springs if I wanted to go softer/harder? AE maybe?

I'm building my f1ultra at the moment and have the motor mount mentioned in your quote. Problem is there is no way to mount the damper perch to the motor mount as it has no screw holes. unless there is some other way to mount the damper perch this doesn't look useable for the f1ultra.

I have the Fr1 chassis and ran into the same problem on my F104 Pro. I was detirmened to use the new motor pod. So you have to drill two holes that match the OEM motor pod and thread them with a 3M tap. It works well!

Mike, how do you deal with a side damper?

maybe epoxy a set screw on the pod? there is nothing to grab onto without drilling.

Hi All,

Here is the Yeah pod fix as promised.
When I first got the Yeah R pod I quickly lined it up with my carbon parts and everything was seemingly ok. I totally forgot about the dampener mount though, sorry guys
The install was actually delayed because the Yeah racing pod I received was bent on one side. The side that the motor mounts to was totally concaved so there was no way I was keeping it. A quick email to TQ and another pod was on the way (great service as always).
On my 2nd attempt to install the pod I soon found that the 4 holes on the pod was not threaded! So I tapped some m3 threads and everything started to go into place but when I slid the axle onto the bearing cups I found that the ball diff rubs on the Yeah Racing axle height insert m2 screw heads Next step was to add countersinks and replaced the phllip head screws with countersunk screws. Once the screw heads are recessed they no longer rubbed on the ball diff.
Then I realized I needed to mount the side dampener Attached is my simple fix for it. I tapped a 3mm hole and assembled as shown.
Disclaimer- thread tapping- be careful not to rush the thread cutting or you will snap the bit. Turn 1/4 turn, remove bit, clean and repeat

The car is my UF1 LeMans entry. It won last weeks UF1 round. Super stable, maybe too stable. At high speed it wants to push. May have to remove the difuser as it is working way to well on high speed sweepers. Low speed steering was on point!

Edit #2. Nevermind. I'm ditching the yeah racing pod as it was issue upon issue with it (rear shaft bind was the last straw) and ordering the tamiya plastic and 3racing alloy one. Hopefully have less issues with those.

Should I be using the shimizu tyres with the standard inserts? Always heard the f104 ones with the thin inserts worked better than with thick yet the f103 rears come with thick inserts.

The one i purchased for my F103 was the same and no thread on the bottom holes, also the height adjusters were also way too tight fit, and will probably have to be sanded down, i couldnít even get the bearings in. I still havenít put it in the car yet. Poor product from Yeah Racing i would not recommend it.

Hence I'm leaving the rear end for last. Still deciding whether I'll use it or not as the bearings were looking to be another issue as well.
