Hi, was looking at getting either the F-60 or the F104 Pro for racing. I really like the look of the F-60 but not sure if the pro would be a better option for asphalt?

any help greatly appreciated

I'm looking at trying the 103 arms on my 104.

From what I can see, the standard upright is held onto the kingpin with a grub screw, but the 3.5mm offset uprights don't have this. Because the 104 upper arm isn't attached to the bottom one, you still get the spring working as it should. However, on the 103 arms, they are connected to each other, so do I move the spring to above the upright? Otherwise, I can't see the spring serving any function.

Any comments or suggestions?

Postscript: I think I can answer my own question - the 103 kingpins have notches in them for c-clips to hold the upright in place. Is this correct?

The entire 103 front end is a direct fittment to the 104, ive just done it to get some extra front track width to match up to the rc10L3o rear pod I've fitted to the rear..works well too

For racing, you want the 104. A few pages back there's an actual list of the things you'd need to add to the F60 to bring it up to racing spec. By the time you do that, you're well past the price of a 104. I'll add that a popular mod for the 104 is to use the F60 body kit, mainly because of the better wings.

As said above the 103 front will be a direct bolt on.I am running that setup right now.
I would suggest running the 103 rear tires so you don't have a
crazy offset thing going on.
The 103 pins have notches to hold the knuckle in place and hold the spring at the bottom of the arm.

I've seen in these F-1 threads that lot's of people think the F 104 is the car to have---but in this SoCal series noted above--which has proven VERY competitive---the Tamiya F104---F103 and the 3 Racing F 109 ALL have victories to their credit. I think only the HPI F 10 has not won a race!! All other's have proven very equal in performance on both carpet and asphalt--with rubber OR foam tires. NO advantage to any car over the other---it's come down to driver and setup-- so pick your car--pick your poison on which one you like the best and go for it!!! Their ALL GOOD!!!
