I will be running my oldskool F103 at TITC next month, (wish me luck )

http://www.titc.in.th/titc/

most other guys are running F104 and FGX's so I thought I will see what the old girl can do, (plus the F103 still seems to kick the F104/FGX on local tracks anyway)

as this has a 20min final which requires one pitstop and tyre change the standard F103 Diff will not be very suitable (it may fall apart and need to be re-tightened correctly etc etc)

I heard the F104 diff may be the solution, can I get this verified as well as what partnumbers would be needed to swap them over,

I am guessing just the diff housing set? or is there anything else?

54158 F104 Aluminum Diff Housing Set

Use the complete rear axle from the F104PRO.
Swap the ballbearing in the diffhousing for your F103 trustbearing and mount the springwashers like this )(
It will result in a very smooth diff(if you have ceramic balls in it and sanded the diffrings down offcourse )
I use that also on my F103.
Have run the car for a whole season without maintenance and still runs smooth.

Thanks for the response Roy.

so I would need to get both the "54158 F104 Aluminum Diff Housing Set" and "54162 F104 Carbon Rear Shaft" ?

Yes and yes.
Loose the ballbearing tho and use the one piece trustbearing what is in your rear wheel of the F103 Tamiya 53136

Gotta love the f103! 15+ year old car with old t-plate and damper disc setup and she's still the queen of f1!

More 103's should be seen racing!

Why not?
You need the F104 axle to use the F104 pro dif parts.
You can use the steel,alloy and carbon axle.
As long as it is from the F104
If you want to use the F103 axle, you need to shorten it.

Problem is that more and more official races are dominated by rules using the 180MM cars.
You can try to convert the F103 to 180MM but that would take out it's charm and handling.
They need to do so as in the states.
Run a 180MM and 200MM F1 class.
This will sort all rules out so everybody has fun.
I still drive the F103 with great plessure and also converted a F104Pro to 200MM.
The F104 is a lot more fun at 200MM

I did it to mine, but decided i wanted to use the steel shaft since carbon is easy to crack. Cut down the orginal one to size and works perfect. So you only need 54158.

I understand that we have to run F104 tyres/Rims, have you any experience with this?
