Tamiya Direct Drive Touring Car

he actually mentioned that in his first post... he's trying to do it on his own w/o the conversion...
looks good so far... now you just need to check that rear axle... also... post more pics of what you did... (under, parts list, etc...)

I might not use mini tires for this project. Instead, got some 1/10 nitro foams here that are almost 60mm in dia. Those should fit perfectly.

Nice build up mailboxck 
Tamiya is releasing a 1/12 Tamiya Racing Master chassis, maybe the F103 GT 'touringcar' parts (ie the rear wheel hex mount and the front uprights) will fit this chassis given the 1/12 chassis the correct overall size for M bodies?
Just alter the wheelbase replacing the main chassis plate with a new one to accommendate the correct wheelbase.
Just a thought

Yep Field 1 does make a kit but the one they make is the short wheelbase. The one I made is med wheelbase (225mm). I also wanted to prove that you don't need all the parts in the Field 1 kit to make one.
I'm still waiting for a part I ordered from Tamiya to make the rear width correct. I need to replace the right side joint to an F104 diff joint found in the F104 PRO kit. Then, I have to cut down the shaft on both sides to make the width correct.
I'm looking at either an Fiat 500 Assetto Corse body or an MX-5.

The only other parts you need is the front knuckles if you run mini size wheels. BUt you said you are going to use 1/10 touring car wheels so you do not need them in for the front.

The F104 diff joint will not make the right side narrow,you need a narrow F103GT spacer,Its the F103GT spacer that causes the problems,you can get just the diff parts from Field one. Because you all ready made a main chassis,but the diff parts will also have to be made from something,There are no Tamiya parts at all to make the right side narrow.

You might be able to grind down the hub,I dont know where my field one kit is right now but both the the inside hub and the F103GT have to be very narrow. I am talking about the hub that is on the left side of the spur gear and the F013GT hub.Field one uses a different style of hub for both pieces.You might get into where the bearing sets in the inside hub before you get it small enough to fit the F103GT hub.
I am not try to discourage you at all,I know a guy that is did the same thing you are doing. But he used the rear hub parts from Field one, The Field one kit doesnt look like much,forget the main chassis,any monkey can cut one out, its the other small parts that make your project hard.
The Guy that makes the kits is a friend of mine so I know what you need to do to make a Mini GT
Good luck and if I find my Field One kit I can take some measurements off of it for you.

Thanks so much! I really appreciate it. I hope I can make it work. I'll give you an update when I get my parts. So far, things are looking ok.
For the diff halves on the right side of the chassis. When I grind it down, it looks like I will have to remove one bearing but I don't think it should affect performance that much.
I'm getting F104 front king pins so perhaps that should help.

F104 King pins are too long to fit Mini wheels,you have to look for something else.

Ran my F103GT and F103GT mini yesterday at a club race.
Surprisingly, the GT held up well against the F104's and F103's. Most were using foams except for the quickest F104 driver. I ran 38 shore Jaco Nitro Shoes at the back and 40 in front. It was quite twitchy in the chicanes but ran good.
The 15 minute mains was a bit of a killer. Others used tire compounds while I didnt. This meant that they got away quick off the starts, but after 5 minutes, I began to reel them in.
After the race, I ran the F103GT mini for fun. The front was 160mm wide, but the rear was still unchanged at 180mm. Amazingly, it ran as well as my F103. I can't wait to put a body on this one and narrow down the rear width.

Does anyone here know how to increase the downforce in the F103GT's Advan Courage body?

There's a small notch in the middle front splitter that can be cut away. Does this have any advantage?
Also, has anyone tried changing the angle of the rear wing to increase rear downforce?
Basically, the F1's are much more advantageous because of their larger front and rear wings. So I need to find a way to make the Courage body work.
